Quad Rings are used as low friction roll resistant seal in piston and dynamic sealing applications.
The Quad Lobe design holds the seal in place when moving and distributes the sealing surface amongst the 4 lobes of the seal.
Quad Rings, O-Rings or metal springs can be utilized within U Cups or other hydraulic seal shapes to energize the entire seal for superior performance.
