About these parts
Oil seals keep lubricant in and dirt out where a shaft turns. O-rings seal in a groove between two parts. Washers seal under a bolt, a valve seat or a gland. We make O-rings in standard and non-standard sizes, and seals and washers to your drawing or sample.

Common questions
Do you make O-rings in non-standard sizes?
Yes. Custom O-rings are moulded to the inside diameter and cross-section you need, as well as in standard sizes.
How do I measure an O-ring for a quote?
Measure the inside diameter and the cross-section in millimetres. If the old ring is stretched or flattened, measure the groove it sits in instead and tell us whether it seals on the inside or the outside.
Which rubber should an oil seal be?
Nitrile (NBR) is the usual choice for mineral oil. For hotter oil, fuel or chemicals, a fluoroelastomer (FKM) lasts longer. Tell us the oil and the running temperature.
