Small cross-section low-friction internal swivel seal
Composite seal for sealing rod of swivel joints and rotary couplings.
This seal is designed to retrofit O-ring glands, to minimize system friction, and to provide a positive seal on the rod. It is used where radial grooves must be kept as small as possible. Up to 3,500*psi. Small quantities are available in 1 to 3 days.
Size Table (Inch)Standard sizes listed below are preferred sizes for new design applications; however, we offer any other seal size as required.Seals are available for any shaft diameter size in 0.001 inch increments without tooling charges, including Functional Range.
