Shaft Seal – Head Assembly (1 7⁄8), Kinney, Rotary Piston, KT300C, Part# 65114

This is a complete head assembly made specifically for the Kinney KT300C . It measures 1 7⁄8 inches.

Think of it as a barrier. It seals the space between the rotating shaft and the stationary pump head . This does two important things:

• Prevents oil leaks: It keeps vacuum pump oil inside the pump where it belongs.

• Keeps air out: It stops outside air from being drawn into the pump, which would ruin your vacuum.

The sealing faces are designed to stay smooth and cause very little wear over time .

You will also find this seal included as a standard component in factory maintenance kits for the KT300C:

• Minor Maintenance Kit (80941700BM) 

• Major Maintenance Kit (80970600BM) 

That tells you how essential this part is for proper pump maintenance.
