A guide to seal material selection
Nitrile (NBR)
Standard in our metal Cam and Groove couplings.
Nitrile is a synthetic rubber offering improved chemical resistance and temperature capabilities to neoprene. The material offers good resistance to oils and solvents, aromatic and aliphatic hydrocarbons, petroleum oils and gasoline's, animal fats and lacquer solvents. It offers poor resistance to strong oxidising agents, chlorinated hydrocarbons, ketones and esters.
Temperature range -50 to 120 Deg C (-60 to 250 Deg F)
EPDM
Standard in our polypropylene Cam and Groove couplings.
EPDM offers good resistance to ozone, heat, steam, strong acid and alkalines. It is not suitable for use in oils, solvents and aromatic hydrocarbons.
Temperature range -50 to 150 Deg C (-60 to 300 Deg F)
Viton
Viton (fluorinated hydrocarbon) offers excellent resistance to acid, altphatic hydrocarbons, oils, gasoline and many corrosive industrial applications. The materials offer excellent resistance to temperature, weathering and gas permeability.
It is not suitable for use against amines, esters, ketones, steam or low temperature service.
Temperature range -20 to 200 Deg C (-4 to 392 Deg F)
Neoprene
Neoprene offers excellent oil resistance, low permeability to gases and resistance to ozone, weathering and corrosion. The material is suitable for moderate acids, alkalines, salt solutions, petroleum and commercial oils and fuels.
It is considered unsuitable for use with strong acids, fats, greases, and most hydrocarbons.
Temperature range -50 to 110 Deg C (-60 to 230 Deg F)
Silicone
The silicone range of rubbers offers excellent high and low temperature properties, far superior to any other grade.
They are unsuitable for use against steam and many hydrocarbons.
Temperature range -70 to 250 Deg C (-95 to 480 Deg F)
PTFE / FEP
Resistant to nearly all chemicals, PTFE and FEP also have good temperature capabilities. They have very limited flow capabilities which makes the use of a rubber filler essential.
The choice of filler will be dictated by the application medium or temperature, as the PTFE / FEP is slightly porous.
Temperature range (PTFE ONLY) -54 to 232 Deg C (-65 to 450 Deg F)
