Adds a gas level indicator and built-in leak detection to an existing W20 30mbar propane bulkhead regulator — single cylinder use, no changeover function. Screws onto the existing regulator's W20 inlet and reconnects the existing hose. For regulators not fitted upright in the middle of the gas locker. Butane only — propane version 01-1620 also available.
The 01-1615 is the single-cylinder version of the Gaslow W20 gauge range — where the changeover gauges (01-1630 and 01-1631 series) add twin-cylinder manual changeover capability, the 01-1615 is for single-cylinder systems where the only requirement is adding a gas level indicator and leak detection function to the existing setup. It fits onto the W20 inlet of the existing 30mbar bulkhead propane regulator and the existing hose reconnects to it — no other changes to the gas system are required.
This is the configuration for 30mbar regulators that are not fitted upright in the middle of the gas locker — i.e. regulators mounted sideways, in the corner, or in a non-upright orientation. If your regulator is fitted upright in the centre of the locker, confirm the correct version for your installation before ordering.
