Master your classic regulator restorations with the professional Scubapro MK5 internal O-ring tool set. This highly specialized kit is custom-engineered to facilitate the flawless installation of hard-to-reach internal O-rings within the legendary Scubapro MK5 balanced piston first stage. Precision-machined from durable acetal, these non-marring service tools slide deep into the regulator body cavities without scratching the highly polished internal walls or critical sealing surfaces. Essential for vintage dive workshops and meticulous technicians, this tool set guarantees a seamless, leak-free overhaul of a legendary dive industry workhorse.
How It Works:
The Scubapro MK5 internal O-ring tool set features a dual-tool approach designed specifically for deep internal chambers. To extract a worn or compressed internal O-ring, use the carefully hooked hook tool to grip and lift the seal out of its internal dynamic recess without contacting the metal walls. When installing the replacement O-ring from your service kit, place the new, lightly lubricated O-ring onto the pilot guide or installation mandrel tool. Insert the tool smoothly straight down the center line of the MK5 body; the precision-tapered sleeve compresses and drives the O-ring down until it expands perfectly and seats evenly into its designated internal groove without twisting, pinching, or tearing.
