Charles Austen ET60

Its not a full size compressor ( by a long way) but it does blow air.
I was given it so dont have the original connector but the data sheet is a bit weird. It says it comes with 18mm and 10mm horizontal connections. BUT they cant be both of those as a thread.

Anyone know what fittings these are likely to be.

Takes me back a bit, 30-odd years or so.

I "think" these are probably linear piston pumps and we used to use the much smaller ones for gas sampling.

I "think" Charles Austen were/are the distributor for Nitto Kohki Medo pumps.

From (vague and distant) memory, they had threaded ports, at least in the smaller sizes we used, threaded BSP (though I couldn't rule our NPT). I think they came with either a barbed hose fitting for a specified hose id, or a fitting for a specified tube od in the threaded port, which we just removed and replaced with a fitting to suit our system.

I suspect the bigger ones may just have hose connections.

Looking at the online drawings for the Nitto Kohki LA60, it looks to have an 18mm od outlet, almost certainly suitable for a 3/4",19mm, bore hose and hose clip. I'm a luddite, currently on a tablet, and can't work out how to post links. Sorry.

Delivery pressures are very low: maybe up to 2 metres of water column (3 psi) and they are brilliant where that is what is needed: aerating a fish pond, for example.

It can be both sizes.
It'll be an 18mm parallel OD aka a straight pipe connection most likely so you can use an 18mm compression fitting, but also threaded to accept a supplied 12mm screw in hose barb, however the thread could be anything.

Thats what i am struggling with. I am trying to identify the thread..
