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.
Key Features & Specifications:
- Targeted Part Compatibility: Engineered for use with Apeks AP5202 (H.P. balance plug for TEK3, US4, US1, DS4, and DS1) and Apeks AP5309 (H.P. balance plug Extrair) components.
- Premium Acetal Build: Precision-machined entirely from robust white acetal (POM-C). This high-grade material is selected for its ultra-smooth surface finish, rigidity, and complete chemical resistance to scuba lubricants.
- Essential Shop Saver: A low-cost tool that prevents costly comebacks and ensures professional quality control on legendary Apeks workhorse regulators.
