17421 Part Number 17179-220 Kit TypeDescription 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
