We stock a large quantity of Standard O-rings and Specialised O-rings to suit any application and environment. Below is a listing of the materials available and their capabilities.

Material	Temperature	Suitable for
Nitrile	-40 to 110c	Most Commonly used for fuel & oil resistance
Viton®	-20 to 205c	Excellent Chemical resistance & high temp
Neoprene	-40 to 120c	Excellent resistance to polar solvents but petrol capabilities are poor
EPDM	-40 to 150c	Excellent thermal stability but poor mechanical properties
Silicone	-60 to 200c
Aflas®	0 to 200c
Kalrez®	-50 to 315c	Excellent heat and chemical resistance

We also carry a good range of back up rings and washers to suit most O-Ring applications.

PTFE O-Rings are generally made from 100% Virgin PTFE and fabricated to very close tolerances. PTFE can be used in environments where high temperatures and harsh chemicals, acids and gases are a problem. It can also be supplied with fillers such as carbon, graphite, glass and bronze.
