The PSS 02-38M-234 Dripless Shaft Seal features a mechanical face design that creates a watertight barrier using a stainless-steel rotor and a stationary carbon flange. The rotor compresses a bellows, maintaining constant contact to adapt to propeller thrust and shaft movement, while an over-bored carbon flange allows for compensation of misalignment and vibration. With a temperature range of 5°F to 225°F and a pressure limit of 15 PSI, this durable seal ensures reliable performance in marine applications.

PSS 02-38M-234 - Dripless Shaft Seal 38 mm, 2 3/4" Stern Tube

The PSS 02-38M-234 Dripless Shaft Seal is engineered for reliable performance in marine applications. This advanced seal uses a mechanical face design to create a watertight barrier between the rotating stainless-steel rotor and a stationary carbon flange. The carbon flange is secured to the bellows, which fits over the stern tube, ensuring a secure connection through hose clamps.

The stainless-steel rotor is mounted on the shaft and compresses the bellows, maintaining constant contact with the carbon flange. This compression allows the seal to adapt to any fore and aft movement caused by propeller thrust. Additionally, the carbon flange's over-bored design accommodates shaft misalignment and vibration, enhancing durability and performance.

Sealing is achieved through two O-rings situated in the collar bore, which rotate with the shaft and do not wear during operation, ensuring longevity.
