Scubapro Piston Bullet, Brass

The Peter Built Piston Bullet is designed to guide the piston easily into Scubapro® first stages without damaging the internal piston stem o'ring. The bullet is inserted into the end of the piston allowing the major diameter to completely cover the knife edge on the end of the piston. Once the piston is installed, the bullet can be removed from the opposite end of the first stage.
