Optimize your workshop efficiency and guarantee perfect regulator tuning with the Apeks ATX/MTX/MTX-R Lever Height Setting Tool. Specifically engineered for scuba service technicians and demanding dive centers, this premium tool ensures exact precision during the final set-up of Apeks ATX, MTX, and MTX-R second-stage regulators.
 
Essential Tooling for ATX & MTX Regulators
Achieving the correct internal lever alignment is critical for preventing performance degradation or unwanted free flows. This specialized gauge is perfectly configured for modern high-performance Apeks variants. It provides a reliable benchmark when matching standard manufacturing tolerances for second stages utilizing the Apeks AP0295 purge button assembly (found across the ATX, MTX, and MTX-R series).
 
Smart Dual-Sided Go/No-Go Design
Tuning is simplified with a clear, functional visual testing approach:
No-Flow Side (Shorter Side): Features no ring indicator. It assures the technician that the lever height is not set too high, eliminating passive air leaks while pressurized.
Flow Side (Longer Side): Verifies that the internal demand valve cracks open exactly when specified, initiating a steady flow when pressed against the assembly.
 
During the fine-tuning process, place the tool squarely and straight against the rim of the purge button cover while adjusting your inline adjustment tool. If one side stays perfectly silent and the opposing side initiates a flow, the regulator is tuned to optimal factory performance specifications.
 
Industrial Grade Construction
Like all specialized equipment manufactured by Scuba Service Tools, this setting gauge is precision-machined from top-tier white acetal. This low-friction, heavy-duty material delivers exceptional dimensional stability and chemical resistance, protecting delicate second-stage components from accidental scratches during bench testing.
