The bayonets I use have a 1/4" male thread. 1/4" x 1/2" brass or black iron bush does it nicely.

These are my gas rigs, one with bayonet.

i thought testing gas pipework with compressed air was a no no due to the water in the compressed air

Think that's only refrigerant pipework.

All the commercial books talk about performing strength tests using air.

But then you're not pumping it up to huge pressures, only a percentage above mip or mop so the moisture wouldn't be forced to condensate.
