Rod Buffer Seal with Backup Ring

Series 124: Rod Buffer Seal with Backup Ring

The 124 Series rod seal is a buffer seal used in the Zero Leak Technology sealing systems and is ideal for high-performance applications. It offers a low-friction design, consisting of a polyurethane seal and a POM backup ring. The sealing lip design is optimized to ensure maximum sealing performance at both low and high pressures. The lip design features a “pump-back” capability, which eliminates pressure trapping.
