leeway, you have to give the part number, mcmaster links only take you to the main page of the item. Regaurdless, they probably are the fittings I have now, which still have the check valve. BUt, i drilled out the back and the spring and detent fall right out, so no worries about that anymore.

Mystichrome, thanks for the link. I may pick some of these up as my newest problem is trying to get the hose to stay on the fittings once i start moving things around.

I can almost see the light as the end of the tunnel!
