PSS 07-N20-0 is a rotor O-ring service kit listed by PSS for 2" or 50mm shaft sizes. It renews the internal O-rings and set screws used to seal and secure the stainless-steel rotor to the shaft.
Specifications and Contents
- Listed shaft sizes: 2" or 50mm.
- Includes two O-rings, five set screws, one Allen wrench, thread lock, and four clamp jackets.
- Does not include a bellows, carbon stator, or stainless-steel rotor.
Fitment and Service Notes
Check the installed PSS rotor and shaft size before ordering. Never reuse a set screw that has already been tightened onto the shaft; follow the manufacturer’s rotor-setting and locking procedure when reinstalling it.
Parts Desk Insight
Select the kit by its exact PSS part number and the shaft size, rather than by stern-tube diameter. Where both imperial and metric sizes are listed, these are manufacturer-supported applications for the same service kit, not an exact unit conversion.
