Black acetal dual-sided lever height setting gauge tool for lightweight Apeks Flight regulators.

Optimize your workshop efficiency and guarantee perfect regulator tuning with the Apeks Flight 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 the ultra-lightweight Apeks Flight second-stage regulator.

Essential Tooling for Flight Regulators

Achieving the correct internal lever alignment is critical for preventing performance degradation or unwanted free flows. This specialized gauge serves as an exact equivalent to the factory Apeks AT75 tool. It provides a reliable benchmark when matching standard manufacturing tolerances for delicate Flight series second stages. Please note that this specific tool should not be used for servicing the Apeks XL4 second stage.

Smart Dual-Sided Go/No-Go Design

Tuning is simplified with a clear, functional visual testing approach:

Flow Side: Verifies that the internal demand valve cracks open exactly when specified, initiating a free flow when positioned.
No-Flow Side: Assures the technician that the lever height is not set too high, completely eliminating passive air leaks while pressurized.

For best results, pair this gauge with an inline second-stage adjustment tool to correctly dial in the assembly within minutes. During the fine-tuning process, it is essential to keep the tool straight and flush against the rim of the purge button cover while adjusting the internal orifice.

Industrial Grade Construction

Like all specialized equipment manufactured by Scuba Service Tools, this setting gauge is precision-machined from top-tier acetal (POM-C). This low-friction, heavy-duty material delivers exceptional dimensional stability and chemical resistance, protecting delicate lightweight second-stage plastics and components from accidental scratches during bench testing.
