The Aqualung Core cover tool opens and closes the delicate cover retaining ring even if it is tightly seized due to saltwater corrosion or over-tightening.
How It Works:
- Place the tool face down with the pins pointing toward the regulator assembly.
- Position it precisely over the Aqualung Core second stage cover.
- Slide all six hardened stainless steel pins inside the small corresponding holes on the cover surface.
- Apply a steady downward force and turn to loosen or lock the cover ring.
Key Features & Specifications:
- Designed strictly for servicing the Aqualung Core second stage regulator cover.
- Employs six pins to engage all holes, outperforming standard two-pin face spanners.
- Eliminates the risk of tools popping loose and gouging expensive regulator parts.
- Machined from non-marring Acetal (POM-C).
- Compatible with Aqualung part number RG912011.
