The PSS 02-85M-700 Dripless Shaft Seal is a mechanical face seal designed for marine use, featuring a stainless-steel rotor and carbon flange to create a sealing surface. The bellows maintain constant contact between the rotor and flange, compensating for shaft movement and misalignment. O-rings ensure no wear during operation, and the seal operates within temperature limits of 5°F to 225°F, pressure limits of 15 PSI, and shaft speeds up to 10,000 RPM. It is made from durable materials like carbon graphite, 316SS, Nitronic 50, and molded Nitrile-PVC, with a shaft diameter of 85 mm and stern tube diameter of 7" to 7 1/8".
