PSS PRO Shaft Seal for 2" Shaft & 3" Tube

The PSS PRO Shaft Seal is designed for maximum durability in harsh conditions, featuring a robust mechanical face seal with stainless steel and carbon components. Its reinforced silicone bellow provides enhanced resistance to corrosive environments. This advanced sealing solution includes external rings, a secondary shaft retention collar, and durable 316 stainless steel hose clamps, ensuring a secure fit. For applications that demand top performance, the optional Nitronic 50 rotor upgrade is available.

The sealing mechanism combines a stainless steel rotor and a stationary carbon flange to create an effective barrier against leaks, adapting to axial movements from propeller thrust while allowing for misalignment compensation. The design accommodates high RPMs, providing reliable operation under pressure.
