Small cross-section low-friction external swivel seal

R67R


Small cross-section low-friction external swivel seal

Composite seal for sealing the bore 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 bore.  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.
