Carlisle ST1 Grease Fitting 1/4 28 Sae Lt 336738

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 grease fitting on the tool, which is a small valve that allows lubrication of the gun’s moving parts. The grease fitting has the part number 336738 and the size 1/4-28 SAE-LT, which means it has a tapered thread that fits the standard hole size for the automotive industry. The grease fitting 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.
