Carlisle ST1 Spring 336735

The Carlisle ST1 is a spray foam gun that requires periodic maintenance to ensure optimal performance. One of the maintenance tasks is to replace the spring on the tool, which is a metal coil that provides tension and balance to the gun’s parts. The spring has the part number 336735 and can be found inside the gun, near the trigger. The spring can be purchased separately or as part of the ST1 complete o-ring kit, which contains all the necessary o-rings and side seals for the ST1 gun.
