Quality O-Ring Seals

Please wait while we load your selection

Help me decide which type I need

Each type of O-ring material has properties better in some way than the other, it may be that they are tolerant to higher or lower temperatures or resistant to different chemicals

There is no such thing as an all purpose O-ring.
The suitability of each type needs evaluating by its resistance to chemicals and the temperature range that it will be exposed to when it is used.
