Plunger Kit 659569-00

This plunger kit is part of the push system inside a cordless caulking gun. It moves forward during use to press sealant or adhesive toward the nozzle. Replace the kit if the plunger is cracked, bent, worn, or no longer moves the material as it should. A damaged plunger may cause uneven flow or prevent material from coming out. Remove the battery and take out the sealant container before starting the repair. Clean away any dried material, then compare the new parts with the old ones to confirm their position and fit.
