Part Number: 07-N03-4

  • Description

    Overtime you may find that you need to replace the o-rings inside the stainless steel rotor of your PSS Shaft Seal. This kit comes with everything you need to get the job done.


    • Allen wrench
    • Set screws x5
    • O-rings x2
    • Clamp Jackets x4
    • Thread lock

    Important Note: Be sure to never use the same set screw on the shaft twice. There are two set screws in each of the two holes in the stainless steel rotor. One is tightened onto the shaft, and the other is tightened onto the first lock it in place against the shaft. The set screws are made with a cup at the base that compresses into the shaft, ensuring a secure grip.
