Simplify your vintage regulator servicing with the professional Scubapro MK10 internal O-ring tool set. Anyone who has ever tried to manually seat a new O-ring deep inside the main body of a classic Scubapro MK10 balanced piston first stage knows how frustrating and time-consuming it can be. This highly specialized multi-piece kit makes the job effortless, allowing you to position the central dynamic body seal perfectly in a matter of seconds. Precision-machined from premium white acetal (POM-C), these non-marring tools guide components into place smoothly without scratching the highly polished internal cylinder walls or critical metal seating surfaces, eliminating intermediate pressure creep.
 
How It Works:
The Scubapro MK10 internal O-ring tool set uses an ingenious push-and-align mechanism to place deep internal seals. First, open the bottom of the MK10 first stage using a seat retainer socket and the top using a standard C-spanner. Position the two custom-fit outer alignment sleeves securely on the top and bottom openings of the exposed regulator body. Place your new, lightly lubricated replacement O-ring inside the guide channel, then use the small, specialized push rod included in the set to slide it smoothly through the sleeve. The internal geometry guides the O-ring directly to its dynamic recess, popping it perfectly into place without twisting, pinching, or tearing.
