The Apeks XL4 lever height setting tool ensures exact precision during the final set-up of the Apeks XL4 second-stage regulator.
 
Achieving the correct internal lever alignment is critical for preventing performance degradation or unwanted free flows.
 
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, eliminating passive air leaks while pressurised.
 
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 second stage with the cover removed while adjusting the internal orifice.
