Common O-Ring materials that are SUITABLE for dynamic and static seal in the environment containing MIL-H-7083 include

• Buna-N (Nitrile): Buna-N, also known as Nitrile rubber, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene.
• Butyl: Butyl (IIR) is a synthetic rubber, a copolymer of isobutylene and isoprene.
• Ethylene-Propylene: Ethylene-propylene (EP) is a copolymer of ethylene and propylene.
• Fluorosilicone: Fluorosilicone combines excellent low-temperature performance of silicone with improved chemical resistance.
• Silicone: Silicone is a semi-organic elastomer with outstanding resistance to extremes of temperature.

The O-Ring materials below are USUALLY SUITABLE for static seal in the environment containing MIL-H-7083.

• Fluorocarbon: Fluorocarbon elastomer (FKM) material is also known by its tradename VITON or Fluorel.
• Hypalon: Hypalon is the traenme of a clasof Chlorosulfonated Polyethylene (CSM).
• Natural Rubber: Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis.
• Neoprene: Neoprene is a homopolymer of chlorobutadiene (CR).
• Styrene Butadiene: Styrene-Butadiene rubber (SBR) has properties similar to those of natural rubber.

O-Ring materials that are NOT SUITABLE for using in the environment containing MIL-H-7083 include

• Polyacrylate: Polyacrylate (ACM) is a class of copolymer of ethyl and acrylates.
• Millable Polyurethane: Millable Polyurethane rubber is made from both polyester and polyether polyols.
