Diaphragm Retainer for Second Stage Regulator
The diaphragm retainer (or locking ring) is the original internal component designed to ensure the stability of the main diaphragm inside the second stage housing. Its function is to keep the diaphragm perfectly in place, guaranteeing peripheral watertightness and correct alignment with the lever.
Key Features:
-
Compatibility: Designed for Scubatec second stages (such as FX3, FX4 models) and compatible with standard size housings.
-
Material: Made of high-strength, rigid, and corrosion-resistant technopolymer.
-
Mechanical Function: Evenly distributes pressure on the diaphragm flange when the cap or front ring is tightened.
-
Reliability: Prevents the diaphragm from shifting or deforming during inhalation and exhalation, avoiding water ingress.
Technical Note: During maintenance, it is essential to check that the diaphragm retainer is free of limescale deposits or plastic burrs that could damage the delicate surface of the silicone diaphragm.
