Guide Rings & Wear Rings
PTFE Guide Ring (PTFE Backup Ring)
PTFE guide rings and backup rings provide extrusion resistance for elastomer seals in high-pressure applications. Made from pure PTFE or PTFE with fillers (bronze, carbon, glass), they maintain dimensional stability across a wide temperature range and offer outstanding chemical resistance. Available in flat, conical, or spiral configurations.
Dimensions, hardness, color, compound and packaging can be developed from your drawing or sample.
