This is the new style seal kit for all newer NorthStar pumps. Most of the time with NorthStar pumps, you typically won't need to change the valve discs as they are delrin, not rubber, so this is the standard replacement kit. Must have the new style U-cup retainer (FLP-38) Which is on all 2013 and newer pumps.
Includes:
- SHW-069 - polyurethane U-cup piston seal
- Rubber piston shaft u-cup seal
- Nynon liner for inside the brass nut.
