ST1 O-Ring 2 Pk Air Piston

The ST1 O-Ring 2 Pk Air Piston is a pack of two rubber rings that are used to seal the air piston in the Carlisle ST1 spray gun. The air piston is a part that controls the movement of the spray material from the gun. The O-rings prevent any leakage or loss of pressure of the air and ensure a smooth and consistent operation. The O-rings are made of strong and flexible material that can resist high pressure and temperature. The ST1 O-Ring 2 Pk Air Piston is one of the parts included in the Carlisle ST1 O-Ring Kit Wetted Parts 336419, which contains all the necessary O-rings and wetted parts for the ST1 spray gun.
