When your tire inflator thumb trigger starts to feel stiff and sticky or leaks it’s probably time for a rebuild.  This is a very simple task which involves removing the piston, replacing the o-rings on the piston, wiping off old grease and grime, re-lubing the piston with included silicone grease and re-installing the piston.  Don’t forget to put a dab of grease underneath the trigger where the piston rubs. 

Includes:

All new piston o-rings 

Silicone grease
