Scubatec FX3 / FX4 Second Stage Purge Button
The purge button (or front cover) is the original external component designed for Scubatec FX3 and FX4 second stages. This element acts as a mechanical interface between the user and the internal regulator mechanism, allowing manual activation of the airflow.
Key Features:
-
Compatibility: Specifically designed for Scubatec FX3 and FX4 series models.
-
Material: Made of high-strength elastomer/polyurethane, designed to maintain flexibility even in very cold water and resist UV rays and salt water.
-
Function: Allows you to act on the internal lever to force air delivery, an operation necessary for draining water (flooding) or for pre-dive tests.
-
Protection and Design: Seals the front of the regulator case, protecting the internal diaphragm from debris and direct water flow that could cause free-flow.
Note: As this component is exposed to mechanical and environmental stress, it is recommended to check its integrity during routine maintenance, ensuring that it does not show cracks or signs of stiffening that could hinder purge activation.
