1. SCOPE:

1.1 Form:

This specification covers a butadiene-acrylonitrile (NBR) rubber in the form of molded rings.

1.2 Application:

These rings have been used typically for sealing at temperatures as low as −55 °C (−67 °F) where resistance to hot petroleum-base lubricating oil is required, but usage is not limited to such applications.

1.2.1 The cross-section of such rings is usually not over 0.275 inch (6.98 mm) in diameter or thickness.

1.3 Safety - Hazardous Materials:

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
