Optimize your workshop efficiency and guarantee perfect regulator tuning with the Apeks XL4 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 compact Apeks XL4 second-stage regulator.

Essential Tooling for XL4 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, cold-water Apeks XL4 variants. It provides a reliable benchmark when matching standard manufacturing tolerances for these ultra-compact second stages, ensuring the demand valve is calibrated to factory specifications after a complete service.

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 steady free flow when positioned against the assembly.
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 barrel.

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 second-stage chrome threads, plastic housings, and purge components from accidental scratches during bench testing.
