This tool, made out of Acetal, is used to verify the lever height during the final set-up of Apeks AT, ATX and MTX-R second stages.

The tool - gauge - has 2 sides. Inside the recesses at the top and bottom of the gauge you will see the label FLOW or NO FLOW; the no flow side also has a small groove machined in the body to make the distinction more apparent.

By connecting the second stage to the in-line adjuster (if available) or LP hose and pressurizing it, the technician is required to place each of the side of the gauge squarely on the purge button and depressing it.

Starting with the NO FLOW side (the word FLOW will be visible), it should not initiate a flow. However, if a flow in initiated the lever height is set too high and needs to be adjusted accordingly and re-checked with the gauge. If the gauge doesn't initiate a flow, proceed to the FLOW side (the word NO FLOW will be visible). This should initiate a flow. If a flow is not initiated, the lever is set too low and needs to be adjusted accordingly. If the latter is the case, proceed again with the no flow side.

In order to obtain correct results, it is important to keep the tool properly aligned with the rim of the purge button.

In-line adjustment tool is sold separately.

Regulator and additional tools are not included.
