Cracked Pump Seal Repair

repair pump seal

This repair works best for pumps with rubber skirt seals. This type of pump is highly prevalent in CPS blasters.

You Will Need:

  • 3/8 od vinyl tube (or whatever size fits)

Simply take the 3/8 od vinyl tube (or whatever size fits) and jam it into the pump head face between the rod and the skirt. You can cut a second piece and get it behind the second flange as well. (you can see it in this picture). This will tighten up any pump that you put it into. And I have done this multiple times, and it works really well. There are a few more pics of this on my minus page.

Only other solution is to wrap it in etape and hope it lasts. –Soakinader
