The Scubapro S600 old model cover tool is a professional-grade workshop instrument, custom-engineered to assist technicians with the safe removal and installation of the front cover on classic 1st- and 2nd-generation Scubapro S600 second-stage regulators. Servicing these iconic, legacy balanced demand valves requires specialized tools that align perfectly with early-generation casings. Using universal pliers or improper keys often slips, permanently scratching the vintage chrome finish or fracturing the delicate retaining ring threads.

This premium service tool guarantees an exact-fit connection by interlocking seamlessly with the factory notches of the early-style cover assembly. Precision CNC-machined from robust white Acetal (POM-C) engineering thermoplastic, it delivers a completely scratch-free performance that safeguards your delicate life-support equipment. Designed with a convenient, textured ribbed outer handle profile, it provides dive technicians and independent service centres with the necessary manual leverage to smoothly turn the retaining ring without risk of slipping or marring the gear.

How It Works:

Preparation: Ensure any vintage factory safety locking pins or side structural clips are fully removed from the regulator casing before attempting to rotate the faceplate.
Alignment: Place the white acetal tool completely level and perpendicular against the front face of the classic Scubapro S600 cover ring.
Seating: Apply gentle downward pressure so that the tool's integrated internal engagement profile recesses slot directly onto the matching teeth of the factory cover assembly ring.
Operation: Firmly grasp the ribbed manual handle to smoothly rotate and open the cover ring. When closing, turn gently to ensure the threads seat correctly without cross-threading or over-tightening.
