This is somewhat racing related (IMG:style_emoticons/default/smash.gif) I bought a new air pump for my old compressor but have to build a new manifold and re-plumb my air connections. Need some help. I'm using two lines, one is 1/2 steel and the other 1/4 copper. I'm using compression fittings on both. What tap size do I use on the 1/2" compression fitting to tap into my new manifold? On one side the compression fitting will be connected to the 1/2" pipe, the other side (minus the compression fitting) will be threaded into my new manifold. Both sides of the compression fitting are the same. Likewise for the 1/4" compression fitting, i.e., what tap size? Thanks. |

Copper is extensively used in applications like that. As long as it isn't in wetted with DI water (which is nasty corrosive stuff) it's not a bad deal. You might loose a bit because of the wet nature of your compressed gas, but not enough to hurt anything. Unless you go to 316 stainless, steel isn't a good choice because of its propensity to rust. Interestingly, alot of places are switching to stainless process gas piping now because brass and copper is geting so expensive.
Looks good. BTW: If I understood the question correctly, you can get fittings from Swagelok (the best) or cheaper ones from McMaster (they call them YurLok or something like that IIRC) and avoid having to use pipe nipples and things like that. They are a bit more expensive but are a very clean solution. |
