Rubber Seals and Moulded Parts for Automotive and Vehicle Parts

• Home
• Industries

Vehicle circuits punish general purpose rubber. Fuel, engine oil, power steering fluid, coolant and brake systems each attack a different weakness, and a seal chosen on price alone usually fails on one of them.

Industry Pain Points

• Oil and fuel contact that hardens or swells a seal chosen without regard to the medium
• Cold medium sealing in power steering pipes and pumps where the compound has to stay flexible
• Suspension bushings that wear out early and take the whole damper assembly with them
• Rubber to metal parts bought from separate machine shops and moulders with no single owner of the bond
• Seal schedules that mix NBR, HNBR, FKM and EPDM across one vehicle programme

What Buyers Here Need

• Compounds selected against the actual fluid and temperature, not against a stock list
• One supplier able to cover the whole mixed material schedule
• Bushings and anti vibration parts where the metal and the rubber come from the same factory
• Repeatable cross sections batch after batch

What We Supply Into This Sector

NBR O-Rings

NBR is the working compound for anything that meets oil or fuel at moderate temperature.

HNBR O-Rings and HNBR Seals

HNBR is the compound we reach for when a nitrile seal has to stay reliable in cold medium service.

FKM and FFKM O-Rings

FKM and FFKM sit at the top of the seal material range and are frequently confused with each other.

Shock Absorber Bushings and Shocker Bushes

Bonded rubber to metal parts fail at the interface far more often than in the rubber, and split sourcing is why.

Y Seals and Y O-Rings

A plain O-ring is not the right answer for every dynamic duty, which is why the Y profile exists.

EPDM Seals and EPDM O-Rings

EPDM has good weather resistance and unusual versatility, which is why it appears across automotive, electrical and electronic products, daily necessities, sports equipment and mechanised industrial equipment, as well as in wires, cables and high voltage and ultra high voltage insulation materials.

Typical Application Scenarios

• Automotive oil seals and power steering pipe seals in HNBR for cold medium service
• Fuel system and high temperature engine seals in FKM and FFKM
• Brake and coolant circuit seals in EPDM
• Shock absorber bushings and shocker bushes with rubber moulded onto machined metal
• General oil resistant static and dynamic seals in NBR

Delivery Capability

• Mixed material schedules quoted on one purchase order
• Standard AS568 sizes without a tooling step
• Metal parts machined and rubber bonded in house for bushing type parts

Guides for This Sector

How to Choose a Rubber Seal Material in Six Questions

Six questions decide almost every seal material choice. Answer them before you ask for a price, and the quotation you get back will be worth comparing.

Why Rubber to Metal Bonded Parts Go Wrong and How to Buy Them

Bushings, mounts and anti vibration parts fail at the bond far more often than in the rubber. Split sourcing is the reason, and it is fixable at the purchase order stage.

Automotive and Vehicle Parts Questions

HNBR is what we use most for cold medium sealing, including power steering pipes and automotive oil seals. Send the fluid and temperature range and we will confirm.

Yes. We have our own machining workshop and coating workshop, so we machine the metal part and mould the rubber onto it rather than buying in a half finished part.

Yes. Twelve compounds are available from us, and consolidating a mixed schedule is the usual reason automotive buyers come to us.

To your drawing. Where the size happens to be a standard AS568 size we can also use the existing mould and skip tooling.
