History

  • Foundation of company Albert Hiby (bronze foundry) in Plettenberg.

  • Enlargement / reconstruction of Albert Hiby manufacturing premises in Plettenberg.

  • Foundation of company Karl M.C. Ehlers by Karl Max Cäsar Ehlers in Hamburg -
    technical distributor to the Navy and shipyards.

  • Typical traded products of Karl M.C. Ehlers in the 1920s:
    rubber aprons, acid-resistant suits, rubber gloves and boots, industrial hoses and transmission belts.

    Typical products of company Hiby: gate valves and taps/valves for mining industry, fire estinguisher fittings like the adjustable estinguisher nozzle 'Primus'.

  • Elaflex joins the Federation of Technical Wholesalers VTH.

  • 'Contiflex' dispensing hose: electrically conductive, smooth Nitrile rubber as suggested by Ehlers; cotton cord reinforcements, interwoven copper strand, hose cover also available in colered versions. The first european dispensing hose with this construction and without metal lining. Flexible, good flow rate. Long lifetime as cars may run over the hose without destroying it - in these years that was the main reason for hose substitution.

    For the new hose type, traditional hose fittings are not optimally suitable any more, this leads to new constructions.

  • Hiby: production of locomotive fittings.

  • Destruction of offices and stocks of company Karl M.C. Ehlers in Hamburg due to bomb raids.

  • Resumtion of activity by Karl M.C. Ehlers as technical wholesaler

    Hiby: resumption of production, manufacturing fittings for locomotives and waggons.

  • Change of buisiness -
    First own developments of refuelling equipment for fluid hazardous cargo such as petrol and benzene.

  • The Hamburg office moves to a new address in Dornbusch 6: retail shop, stock, administration.

    Shortages in post-war economy lead to creative business ideas based on recycled materials, eg unused artillery cartridges are transformed to to insecticide spraying equipment to combat phyloxera in wine regions.

    Start of the contribution of Karlheinz Ehlers (son of Karl M.C. Ehlers) as commercial/technical employee.

  • Begin of Elaflex refuelling equipment buisiness:
    Aircraft refuelling hose assemblies for the 'Berlin Airlift'.

    The Royal Air Force required newly developed hose systems, on short-term notice. This was the beginning of our partnership with Continental, to mutually develop safe and well-performing refuelling hoses for petrol stations, road and rail tankers, tank ships and bunkering boats and aircrafts.

    Some details about the Berlin Airlift hose assembly: the previous size DN 32 had to be increased to DN 50, for a faster refuelling of the 'Rosinenbomber' aircraft. This made new hose couplings necessary - brass hose tails with chainsaw profile, and crimped brass ferrules. Traditional hose tail attachment with steel ferrules was dismissed due to danger of sparks, and the (then) common wire attachment was not suitable due to the steel helix embedded in the new DN 50 hose.

    Hiby: death of Albert Hiby in November 1948, son Hans Hiby takes over the company.

  • The company Karl M.C. Ehlers transforms to be a system provider/expert for hose assemblies. Own development, own know how. Hose and couplings are put together to well-balanced units, the philosophy is that self-assembly by the user (e.g. for repairs) should always be possible. The goal is production ond product range within a modular system, meaning that per DN size there should be only one hose clamp system - independent of the hose type (thick or thin, with or without helix. The new system to be developed must also avoid assembly errors and should lead to less stockkeeping.

    The production of large scale components is not done in-house any more but on exclusive basis for our company, by external suppliers. Ideas, construction, stockkeeping, assembling and logistics get core competence of our companies success.

    Hiby: production start of components for the transfer of petroleum products.

  • Hiby: Patent for easy operation petroleum valves.

  • Foundation of 'Gummi Ehlers GmbH' as sister company of Karl M.C. Ehlers:
    specialisation in the development and sales of rubber hoses for flammable fluids.

    Building up a new distribution system - OEM, reseller and repair & maintenance companies now have own intermediary stocks with products of Karl M.C. Ehlers.

    'Titania' crimped cone threaded fitting for electrically conductive rubber dispensing hoses. This is the predecessor of the ferrule coupling of today.

    Hiby: manual nozzle "Universal" for vehicle refuelling, licensed production for an important dispenser manufacturer. The product is manufactured in large amounts.

  • Start of the distribution of Elastic Bellows EMD for the installation in pipe systems - predecessor of our ERV Rubber Expansion Joints.

    The companies move to a new Hamburg office in Rothenbaumchaussee 140. Due to lack of space, soon many external storage rooms and workshops must be added.

  • Foundation of 'Elaflex GmbH' by Karlheinz Ehlers. First, the company is specialising into the distribution of special couplings for the petrochemical industries, later the scope is enlarged to Rubber Expansion Joints and nozzles.

    The changes are reflected in the modification of the company logo. Previously there was an anchor showing the close connection with the maritime sector, the new brand shows a refuelling hose assembly, stylised as large "E".

    Hiby: manual nozzles ZV-20 (wet hose) and ZL-20 (dry hose).

    Road tanker hoses, start with a new construction and a new brand: 'Yellow Band' TW hoses. As all Elaflex hoses in standard sizes with BRAIDED reinforcements. This is complex to manufacturer, but the resulting hose is lightweight, more flexible and resistant to higher pressure as conventional hoses with wrapped cord plies.

    The oil industry demands an automatic petrol station nozzle. This is the beginning of co-developments with Hiby.

    Elaflex is granted general distribution right for Hiby nozzles - during the first years with the exception of large OEM.

  • Combined cotton-copper strand to reach a safe and permanent electrical resistance of hoses -
    co-patented from Elaflex and Continental.

    'Titan 100' dispensing hose supersedes the old Titan type in sizes DN 20 and 25.

    The companies Karl M.C. Ehlers (father) and Elaflex GmbH (son) work closer together and slowly prepare a fusion.

    Lightweight drum dispensing hose FP for motor bike refuelling, oil filleng etc. - various types.

    Hiby: manufacturing start of the automatic nozzle 'Unimatic'.

  • Common new development with Hiby: manual nozzle DN 30 for flowrates up to 150 lit/min.

    'Blue Band' solvent hoses LM - based on HD and TW hoses. With the new combined cotton-copper strand, blue NBR special rubber linging, cover Neoprene grey (changed to black some years later).

    Elaflex supplies fist 'TW' couplings to the new 'Norm-Schnellschlußkupplung' standards of the Mineralölwirtschaftsverband (Association of German Oil Companies).

    General Utility Nozzles ZL in easy operation construction, with a packing gland that can be re-tightened.

    Hiby: construction of two new production halls, annex to office buildings. Apart of petrol station nozzles, nozzles and taps for beverages are manufactured (own patents), furthermore angle check valves and hose couplings.

  • 'NORM-AL' hose coupling system: TW 500 (DN 65/75) and TW 1500 (DN 40/50) with hose tails - one or two parts. Material initially hot stamped aluminium. With 'Double-V-Seal" of combined hard/soft Vulkollan (Polyurethane).

    Hoses can now be fitted with five different mounting systems: clamping rings, ferrules, band clamps and (new:) 'NORM-AL' clamps - the one-part predecessor of Spannfix, still without hinge.

    Stand pipes to TW standard as hose protecting connection between road tanker hose and dome filler inlet of the underground storage tank of petrol stations.

    TW Standard flanges TWF of aluminium and brass - with threaded nipple, or sight glass. An alternative to the classic welding flange.

    First versions of rail tanker couplings KWK and rail tanker adapters KWZ.

    Plastic sight glasses SG, threaded dust caps BK, dust plugs BS, reducing nipples RN, welding nipples AN, dip tube fittings.

    Firs pricelist for "Yellow Band" TW hoses and HD hoses. Maximum length 31 metres - 40 mtr. is still a special version.

    Manual wet hose nozzle ZV Universal ZVU (ZV 20) in licensed production - size DN 20, flow rate up to 80 l/min.; the first time with our (nowadays renown) closure principle against the flow ... but insted of a poppet still with a valve plate.

  • PHD as alternative to our TW hoses, for road tankers. Later, this type remains only to be used for special aircraft refuelling applications.

    An improved band clamp for simple applications SK hevy duty clamps for strong, uniform hose tail assembly, avoiding deformation of destruction of the rubber hose.

    The TW coupling programme is supplemented by TW-Norm connection clampsn TWV and adapters TWÜ.

    A range of reinforced, conical special couplings for hot bitumen is introduced - available connections TWN (TW-Norm) couplings, 51/2" rail tanker couplings, Witworth, flanges.

    ZV 20 is now available with guards adopted for dispensers of various brands.

    Hiby: after a series of modifications, the Unimatic Nozzle serial production is gaining importance, also being exported.

  • 'White Band' hoses for foodstuffs. Initially they have the type names HD-W (without helix) TW -W (with helix).

    Manual wet hose nozzle ZV 35 (100-250 l/min) with 2" male fixed hose inlet, optional with spout or MK coupling. Also as dry hose version ZV 354 without check valve.

  • Finally a proper company building in Gotenstraße 20, Hammerbrook/Hamburg. 2700 square metres, four levels. Gummi Ehlers takes 2000 m2 in the building, Elaflex 700 m2. The workflow improvement is phenomenal. Offices, production, stock and dispatch with modern ramps.

  • Female swiveling threaded hose couplings for Titan 100 dispensing hoses provide better protection against hose damage due to torsion.

    Manual wet hose nozzle ZV 50 with 2" male fixed hose inlet, optional with spout of MK coupling. Dry hose options without check valve also available.

  • Serial production of the automatic nozzle ZVA 20. Size DN 20. Glued-in, one piece stamped short length spout - suitable for the small dispenser nozzle boots which were still common in Germany. The spout already showed the characteristic notches. Fixed hose inlet male or female, three guard type options for all dispenser types, the grey scuffguard was still an option. Good minimum cut-off properties, proven lever sealing system. To-the-penny dispensing now was possible due to closure of the valve poppet against the flow. 2 speed lever latch for one hand operation, low pressure drop, robust, shockless closure. This was a revolutionary product.

    'Brown Band' hoses HB for hot bitumen in 3" and 4". Due to less inner friction and improved flexibility, this new type superseedes previously common metal hoses - handling of those types often was only possible by two persons.

  • TW couplings with special seals, for hot bitumen hoses are offered to the previous special conical couplings. In the following years these are preferred as they proove to be much safer in operation as the old Perrot/Kardan system.

    Our standard L.P. Gas hose is improved gets the type name 'Orange Band'. Burst tests confirm: more than the requested "factor 5", for maximum safety.

    Manual nozzlel ZV 25, size DN 25.

  • ELAPAC grey: new type flange sealing material, made of Perbunan-NBR and cork dust, initially also asbest fibres. Elapac superseedes the previous type FD 85 ab. It is available as punched seal, sheet or coil. Approved by the German military and German Rail DB.

    After years of effort, oil companies are being convinced to introduce standardised measurements for road tanker hoses and threaded fittings. There was a colourful mix leading to many practical compatibility problems R-threads (similar to BSP), WW- (Witworth), Rd- (Round) and special theads, e.g. 88x1/8. This is the beginning of Elaflex' participation in the creation of standards.

    Elastic Rubber Expansion Joints Type 'ERV' - a common development with Continental Hannover. Initially, ERV Yellow Band are offered in DN 80 / 100 - a short time later, DN 50 and 150 are added. The unified construction lengths, swiveling flanges with push-through holes for bolts, the flat shape of the ballows and other advantages make ERV the technical pioneer in the following years.

    ZVA 19
    : the export version of the automatic nozzle ZVA 20. With interchangeable long spout, new guard types, strainer, safety-cut-out ball valve and sealed diaphragm cap against non-authorised interventin. The beginning of the international success of Elaflex / Hiby forecourt products.
