CHECK valve for tank to compressor

[BobsterIT]

I have a Hill Ec-3000 and a 45min SCBA tank. I heard that you can connect a check valve between tank and compressor to help with filling tank

Can someone describe what I need and where I can get i?

Thanks again

Eaglebeak, a check valve not a fill valve.



PS, I can’t find a good one either.

Look again. There is a non-return or check valve inside the fitting. These can be combined with other fittings to suit just about any configuration for example.

That middle one is exactly what I need. Is that made up of both 1/8 NPT? I'm a bit tired of doing the frantic dance as I approach 4,100 psi lol.

These are all NPT threads but you can make them with 1/8 BSP or M10x1 fittings if you already have those types in your spares. The male to male can be used in both directions but the others will only flow in the direction from the foster end towards the threaded end.
