The ST1 Side Seal Poly 50 Pk is a pack of 50 rubber seals that are used to seal the sides of the Carlisle ST1 spray gun, which is a device that applies spray foam insulation to various surfaces. The side seals prevent any leakage or contamination of the spray material from the gun and ensure a smooth and consistent application. The side seals are made of polyurethane material, which is resistant to abrasion and chemical corrosion. The ST1 Side Seal Poly 50 Pk is one of the parts included in the Carlisle ST1 O-Ring Kit Complete For Gun 336421, which contains all the necessary O-rings and wetted parts for the ST1 spray gun.
