Product Description

Rubber O-ring

O-Rings are one of the most common seals used in seal design because they are relatively inexpensive and reliable. O Rings seals are available in various metric and standard sizes.

In general o-rings are specified by internal diameter and the cross section.

O Rings made to British Standard Imperial (BS) and British Metric (RM) sizes as well as Swedish, German, French and Japanese (JIS) metric sizes in Nitrile, Viton, Silicone, Flurosilicone, Ethylene Propylene (E.P.D.M.), Neoprene, NWC (National Water Council approved),FEP (Viton and Silicone encapsulated), High Nitrile and Food Grade materials in a variety of shore hardness`s, as well as in P.T.F.E. to suit both static and dynamic applications.

PTFE Encapsulation

Combines excellent chemical and temperature resistance of PTFE o-rings with elasticity of its core material of Viton or Silicone. PTFE FEP Encapsulates (encloses) the core material of either silicone or Viton elastomer.
These O-rings are oil resilient and heat resistant. The PTFE FEP encapsulation provides sealing effect, and the inner elastomer provides constant pressure of the encapsulation to the sealing surface. Good for sealing corrosive fluids. PTFE coating makes them virtually impervious to most solvents and chemicals.

Average total shore A hardness:
85-90 shore A silicone core
90-95 shore A Viton core
The PTFE FEP encapsulation complies with part 177 of Title 21 of the Food and Drug Administration's regulations for safe use as articles or components of articles for producing, manufacturing, processing , preparing, treating, packaging, transporting, or holding food in accordance with regulation 177.1550

PTFE Encapsulated Silicone Color is clear with a brick red inner ring.
PTFE Encapsulated Viton Offers greater chemical resistance than silicone. Color is clear with a black inner ring.
Temperature range: -75° F to +400° F.

Meets ASTM D2000 2BE720A14B14E14E34F17.
Temperature: -40° to 250° F
