Nine Piping Solutions

PTFE O ring is a highly resilient O-ring material unaffected by virtually all known acids, alkalis and solvents. It is tough, abrasion resistant and capable of withstanding temperatures between -200°C to +250°C. It also possesses outstanding weather, ozone and electrical resistance

NBR (Nitrile) is the most cost effective and commonly available O-ring material. Ideal for use as seals for pumps, drive belts, and other general engineering applications in the hydraulic and pneumatic industry. NBR is good for applications where the O-ring is exposed to fats, greases and animal or vegetable oils.

Quad o rings nearly have the same sealing principle as the O-ring sealing. However, they provide less friction than the conventional O-ring and there is no spiral twist. It eliminates the tendency to roll in the groove. The sealing is achieved by the diametrical squeeze in a right angled groove.

An encapsulated O-ring comprises an elastomer energising core, which has a seamless jacket made from fluoropolymer. The elastomeric core may be Fluorocarbon (Viton/FPM or Silicone). The jacket is made from Teflon® F.E.P. (Fluorinated - ethylemnbmbnne - propylene).

EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals.

Neoprene® o-rings is the first synthetic rubber developed commercially, in 1930 by a DuPont chemist, and exhibits generally good ozone, aging and chemical resistance. Chloroprene (CR) is a multi-purposed elastomer which yields a balanced combination of properties.

Silicone o-rings have excellent heat, ozone and corona resistance and have good dielectric stability and resistance to many oils, chemicals and solvents. Silicone o-rings maintain the best flexible property at low temperatures but have low tensile strength and low wear and tear resistance.

Viton® O-rings have excellent chemical resistance and can be used at temperature range of between 15°C and 200°C. Although generally more expensive than NBR (Nitrile) O rings, FKM has found wide acceptance in the aircraft, automotive and chemical industries.
