Help...finding the right piece

Unread postAuthor: achs_xc » Thu Feb 05, 2009 5:45 pm

I captured this from spike33127's youtube "making a QEV" video. Does anyone know what the three parts are that I labeled with arrows and where can I get them?

The big T thing is a brass female T, the long skinny object looks like a hose barb, and the other thing is the piston.

If I were to walk into Lowes, Home Depot, etc, what would look for. Is the "T" a compression fitting or something else? And what are the other bits called? I understand it is his piston.

You go to the (bathroom) plumbing area. Should be near the PVC isle.

That is a hose barb, and the piston is a brass piece of some sort, likely with a sealing face.

I have actually been thinking about those pieces myself, the T does not look like a regular NPT threaded T, I'm not sure why, but it really seems like a hose thread, those O rings also look like hose rings, I could be wrong, probably am... but oh well.

I have actually been thinking of building a QEV, since my last piston gun was a dud, so my next one will be modular so I can fix things easier...

Good luck!

Does any one speak french.... :lol: :lol: :lol: . also the lower piece looks like part of a compression fitting and so does the tee because look at the other two parts over on the top left, arent they the rest of the compression fitting.
