The ultimate protection sleeve for flawless, damage-free first-stage O-ring installation.
 
Ensure a perfect seal during regulator rebuilds with the specialized Apeks balance chamber O-ring tool. This precision bullet-style tool is an indispensable asset for scuba service technicians, designed to guide the high-pressure balance chamber O-ring into its exact position on Apeks first stages without structural compromise.
 
Attempting to slide a delicate O-ring over bare, exposed metal threads can easily result in microscopic cuts or tears, causing frustrating intermediate pressure creeps or leaks later on. This protective sleeve acts as a smooth bridge, guaranteeing a perfect seat every single time.
 
How It Works:
Cap It: Simply place the sleeve directly over the sharp external threads of the high-pressure balance chamber plug.
Slide It: Gently slide the replacement lubricated O-ring down the smooth, tapered body of the tool.
Seat It: The O-ring drops directly and flawlessly into its dedicated groove, completely bypassing the threat of sharp thread edges.
