Niels Christensen invented the O-Rings, He invented the o-ring while working on the development of automotive braking systems. Christensen received a patent for his O-ring in 1937, however, manufacturers were not interested until World War II broke out. He sold his o-ring to the military. This “simple” O-ring ensured that the then still complex technology advanced rapidly. The O ring rubber epdm as a seal is indispensable in today’s technology.
The O Ring:
The O-ring is currently the most widely used seal in the world. They are fairly easy to make and assemble.
You indicate the size of an o ring rubber by means of the inner size (ID) and cord thickness (CS).
O-rings are available in different elastomers (rubber types) and hardnesses (Shore).
KTW, USP, NSF 51 61, WRC, WRAS, FDA, R67 01.
We also provide o-rings with a coating. An o-ring coating is used as an assembly aid or to reduce friction. Coating options: Silicone grease, ptfe, teflon, molykote, talc.
Also available: O-rings according to regulations such as; Rohs ( Restriction of Hazardous Substances ), Reach ( REACH: Registration, MIL R, NAS, Evaluation, Authorization and Restriction of CHemic substances: the new European regulation for chemicals)
We supply the following o-rings:
O-rings NBR ,O-rings FVMQ Fluor Silicone, O-ring Epdm, O-ring Hnbr, O-ring FKM / FPM Viton, O-ring MVQ Silicone, O-ring ACM Polyacrylate, O-ring FFKM ( Kalrez Chemras Parofluor ), O-ring IIR Butyl, O-ring CR Neoprene, O-rings AU Polyurethane. A common type are the epdm o rings. This is because o rings epdm have good properties.
Chemical resistance of o-rings:
The choice of the right o ring rubber also depends on what it comes into contact with. We help you with this choice. We also carry out research on the o-ring.
We supply the right o-ring that comes into contact with e.g. sunlight, ozone, uv radiation, fuel, gas, lpg r67, diesel, petrol, water, drinking water, oil, grease, kerosene, hydrocarbon, hydrogen, alcohol, acid, acids, alkalis, chlorine, fda foods, nutrient resistant o-ring . We also supply Silicone free (100% Silicone Free) o-rings for glass, glass industry, automotive, automotive industry.
