The GC5 – Gas Connector is a large bore, full flow adaptor for attaching to the 9/16” UNF 2nd stage inlet. This allows the Auto Air type hose to be easily connected to APD’s OCB, ADV or any 2nd stage without impeding their performance.

The Auto Air female snap connector - the GC1A (shown right) that connects to the GC5 has a standard 2nd stage thread. Therefore, to convert your OCB to use the new GC5 fitting you simply screw the GC1A female snap connector onto the end of your existing OCB supply hose. The GC1A is available on this site.

Alternatively, complete AutoAir hose assemblies are available from APD (with the AutoAir snap connector and a standard 3/8" UNF first stage end) in various standard lengths, or in fact, any length you require.

Please order bespoke length hoses by telephone: 01274 307555

The standard length hose  IS

EV50/24 - 24" Auto Air hose
Note: These hoses utilise AP's re-usable fittings which means you can adjust the hose length exactly to suit your configuration and then refit the end.
