RayburnGuy Posted November 30, 2009 Report Share Posted November 30, 2009 The threads on my regulator and airbrushes are all metric (British Pipe Threads) and the threads on the quick connects for my new compressor are NPT. (National Pipe Thread) Does anyone know where I can find an adapter that will allow me to hook up my NPT quick connects to the metric threads on my regulator? I've tried everything locally and haven't found anything. thanks guys, Ben Quote Link to comment Share on other sites More sharing options...

BobP Posted December 1, 2009 Report Share Posted December 1, 2009 I'd check with Coast Airbrush or Dixie Art. Dixie carries quite a few types of adapters and the ones I've gotten from them were good quality. Only problem with Dixie is their shipping, which is exorbitant on orders less than $50.

clemmy Posted December 1, 2009 Report Share Posted December 1, 2009 Sorry, unless you can supply a brand, I'm not familar with the British, unless it's simply metric??? The best source I know of is Chicago Airbrush, but even then, I'm not sure what your british measure is..i.e. there's U.S. 1/4", 1/8", Badger, Paasche, etc. Quote Link to comment Share on other sites More sharing options...
miragestalker Posted December 1, 2009 Report Share Posted December 1, 2009 (edited) My local dealer has a great selection of stuff. I don't know what you need but here is his hose and fittings page. Scroll completely as the fitting are all over the page. I see a few stuff labeled NPT to NOS to Quick Male to Quick Female etc etc. They are under the title AMFLO. I am in Los Angeles, he is in San Diego, but I get my stuff next day Good luck!

Frank Posted December 1, 2009 Report Share Posted December 1, 2009 If by chance your regulater is metric, get an npt one then go to the page that Miragestalker said and get the adapter from npt to your air brush. These guys are top notch as far as service goes. TCP Global I mean. Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted December 2, 2009 Author Report Share Posted December 2, 2009 I called TCP as that was where I ordered the brush and compressor kit from. They told me all their stuff was metric. (British Standard Pipe Thread) The literature that came with the compressor even states these are metric threads. He told me they have nothing that will convert BPT to NPT. Has anyone else had this problem and if so how did you solve it? Quote Link to comment Share on other sites More sharing options...
Frank Posted December 2, 2009 Report Share Posted December 2, 2009 What kind of brush do you have. Here is a thought cut the hose and put a barbed fitting on with npt threads and call it a day. I have not heard of this yet. Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted December 2, 2009 Author Report Share Posted December 2, 2009 I've gotten a bit of a "schooling" on different pipe threads in the last few days. Apparently the regulator that came with the airbrush kit was from overseas and was packaged in the kit by TCP. The regulator uses BSP threads. I confirmed this through a TCP technician. This is where it got confusing to me. BSP threads are a straight thread and sized in Imperial nomenclature the same as NPT threads. !/8".......1/4".........3/8" and so on. It is not considered a "metric" thread. The BSPT thread is a tapered thread like the NPT, but is sized differently. The difference in the BSP and NPT threads is in the degree of pitch the threads are cut on and the fact that the NPT thread is tapered and the BSP is not. I have found a supplier that has an adapter that converts BSP to NPT so here's hoping this problem is finally solved. If nothing else, maybe this will save someone some trouble down the road.
