The 8-ST PTFE Kit includes 325 PTFE back-up rings in 36 popular sizes, sized to standard O-ring dash numbers. These rings prevent O-ring extrusion in high-pressure applications and enhance sealing performance. Made from chemically inert PTFE, they are compatible with all hydraulic fluids and perform well in high-temperature conditions. The scarf-cut design allows for easier installation and provides reliable support and extrusion resistance in demanding sealing environments.
