The PSS 02-314-512 Dripless Shaft Seal is a mechanical face seal designed for marine applications, using a stainless-steel rotor and a carbon flange to create a reliable, leak-proof seal. The bellows compress to maintain consistent contact between the rotor and flange, compensating for propeller thrust, shaft misalignment, and vibration. It is built with durable materials, including molded nitrile-PVC for the bellows and precision-lapped carbon graphite, allowing it to perform efficiently under various temperature, pressure, and RPM limits.

PSS 02-314-512 - Dripless Shaft Seal 3 1/4" 5 1/2 Stern Tube

The PSS Type A Shaft Seal is a highly effective mechanical face seal designed for marine applications. It ensures a reliable and dripless seal around the shaft to prevent water ingress into the boat's stern tube. The precision-engineered design uses a combination of stainless steel and carbon components to deliver long-lasting performance and compensate for shaft misalignment and vibration.
- Stainless steel rotor and stationary carbon flange create a durable sealing surface.
- Compression of the bellows ensures consistent contact between the rotor and flange.
- Carbon flange “floats” around the shaft to handle misalignment and vibration issues.
- Sealed to the shaft by two O-rings that rotate with the stainless-steel rotor.
- Bellows made from molded nitrile-PVC for enhanced durability.
