X-Ring / Quad Ring / Nu-LIP

Less friction no twist – X-Ring / Quad Ring / Nu-LIP replacement for O-Rings

M Barnwell Services X-Ring / Quad Ring / Nu-LIP are double-acting pressure seals used an alternative to O Rings where spiral twisting and rolling is a problem and are available in a variety of materials.

They can be used in the same groove dimensions as O-Rings but because of the reduced friction resistance can result in longer service life in certain applications.
