The Rodaviss kit (High Temp PTFE) is a female threaded screw cap designed to thread with the externally threaded socket of a 45/50 joint. The 45mm joint threads with the Rodaviss for added reinforcement allowing for a vacuum-tight, greaseless seal that is easily separated, eliminating the risk of stuck joints.
