Scubatec FX3 / FX4 Second Stage Diaphragm
The second stage diaphragm is the original flexible Scubatec component designed for the FX3 and FX4 models. It is the sensitive element that reacts to the negative pressure created by the diver's inhalation, activating the supply lever to deliver air.
Key features:
-
Compatibility: Specifically designed for Scubatec FX3 and FX4 series second stages.
-
Material: Made of high-quality silicone, chosen for its high elasticity, chemical resistance, and durability.
-
Design: Features an integrated rigid central disc for precise contact with the regulator lever, optimizing breathing sensitivity.
-
Function: Acts as a barrier between the external environment and the interior of the regulator, allowing for the modulation of airflow based on breathing phases.
Maintenance advice: The diaphragm is a vital component subject to natural wear and aging. It should be checked periodically for cuts, holes, or loss of elasticity, and replaced during routine regulator servicing.
