PSS O-ring kit for 28mm + 1 1/8' Shafts

If you find that you need to replace the O-rings in the stainless steel rotor of your PSS shaft seal, use this O-ring kit. This kit contains everything you need for this job. Important note: Use the locking screws only once. There are two locking screws in each of the two holes of the stainless steel rotor. One locking screw secures the rotor on the Shafts and the second secures the first locking screw. The locking screws are made with a pointed collar at the base. This ring presses into the Shafts and thus ensures a secure hold.
