Is there an adaptor for this guage to use with Oceanic XS2?
HANS G This gauge is simply to be connected to a low pressure connection hose and is designed to help measure the low pressure (second stage). Any regulator connected to the second stage can be tested, as long as you have two low pressure hoses connected to the first stage. One hose for the gauge and one for the second stage regulator.
Hope this makes sense.
GARY H I know of no such adapter.
GARY C The gauge plugs into the low-pressure hose. I suppose if the BCD had a non-standard connector, that particular LP hose would have to match the non-standard connector.
CHARLES S If you have an Air2 style hose attached to your regulator (larger opening), it is just as cheap to buy a standard LP inflator hose and attached it to the regulator first stage when you are testing the regulator while servicing it.
TUNGAN H I'm not sure. Typically, the quick release air connections are a large and small size. This is the small size. You can probably make it work if you change the hose rather than getting an adapter. This may be a cheaper option to trying to find an adapter. You may be able to find the large fitting at a hardware store. Take your XS2 hose to the hardware store and see if it fits the pneumatic tools. If it does, see if you can twist off the gage fitting and substitute the tool fitting. If not, just buy a hose from your local dive shop and save trouble. Good luck.
