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
alkalis. 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, alkalies,
salt soloutions, 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 excllent 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)
