High-Speed Wear Rings


	Profile


Rod Installation	Piston Installation

Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.

Gap Size—Gap size is the maximum distance between the split ends of the ring while it is in use. Rings are closed when not in use.
