DOT fitting Vacuum Line setup
Sorry, not done yet, what a let down. But has anyone else used DOT air brake/line fittings for vacuum lines before? here's what I'm talking about, the black plastic connectors.
vac lines Fastenal
They use hard line and are a push connect type. You just cut your line, push it in and pull and its all set. To remove you push them back in and hold the connector to remove. They are good to over 100psi, and pretty small and clean.

Anybody done that? I have them availiable to me at work, so with the whole 6 or 7 lines I need, I could make it look pretty damn good and build brackets to hold it all that would keep everything straight and linear. Much better than the rubber line mess.

I will see how many I can nab from work without getting bitched at. 830,000 in inventory, I'm sure 10 bucks of dot fittings won't be anything to cry over. I'm thinkg 90's, straights, and y's with a few 1/4 or 3/16in pipe thread fittings.

Those look like pretty standard QD fittings. Most of them get their seal from positive pressure. BUT really once you seat the seal with positive pressure the first time they typically dont leak under vac too badly. Course there might be more than meets the eye in the DOT fittings that makes them special, but I doubt it.
