P.S.S. Dripless Shaft Seals 1 1/2" & 1 9/16" Shaft Size
P.S.S. Dripless Shaft Seals are an ideal upgrade for power as well as sail boats. Constructed of long life marine materials. Shaft diameters 3/4" to 6". Please choose your stern tube and shaft size from the box above. The P.S.S. Shaft Seal is a mechanical face seal. The seal is created between the flat surfaces of the rotating stainless steel collar, the stationary carbon flange and rubber bellows. The bellows is attached to the vessels stern tube (note: Specify Stern tube diameter when ordering by selecting the apropriate radio button above). Compression (pre-load) maintains contact between the faces and allows the PSS to compensate for the thrust from the propeller. The carbon flange is bored larger than the shaft diameter, allowing it to "FLOAT" around the shaft and thus compensate for most misalignment and vibration problems. The stainless steel collar is sealed to the shaft by two O-rings that are recessed into the bore of the collar. These O-rings rotate with the shaft and stainless steel collar and do not experience wear during operation. Dripless, maintenance-free, stuffing box replacement shaft seal.Three year manufacturer guarantee A.B.S. approved Made in the USA Standard equipment on Alden Yachts, Wellcraft, Bayliner, Donzi Yachts, Ocean Alexander, and others
