Back-Up Ring 17421 is manufactured from PTFE (Teflon) to provide superior anti-extrusion support in high-pressure hydraulic systems. Its low-friction properties enhance dynamic sealing performance while maintaining chemical and temperature resistance. Designed to reinforce primary O-rings, it prevents deformation and extends seal life under fluctuating pressure conditions. Ideal for pumps, valves, and pressure control assemblies, this component contributes to improved system reliability and reduced maintenance requirements.
