I know this is an old thread, but I just ordered some fittings and adapters for my ARB and I thought I'd share the info.
The fittings at the compressor to the air valves are
1/8" x 1/8" BSPP,
British Standard Pipe Parallel thread. The outlet at the airlines are also 1/8" BSPP. As stated above the plastic airline is 5mm.
BSPP/NPT pipe fittings, BSPP push in fitting (
Metric Acetal Instant Tube Fittings ) and couplers (for trail repairs).
I ordered the fittings from :link1:
McMaster Carr:link1: and all of these fittings are a stock item.
The push in fitting are on page 135.
BSPP threaded fitting are on page 20.
BSPP to NPT adapters are on page 21.
Other tubing and fittings (metal & plastic) are located between pg. 16 - 152.
These page numbers are from Catalog 110, the new catalog and their website are pretty much the same. For the website, use the terms listed in
GREEN from above for searching.
Search terms for Mod Tech:
ARB , hard line , air line , conversion , quick connect , where to buy , brass , compression , street , nipples , reducer , union , steel , female , male , thread , BSPT , size , street elbows , nickel plated , stainless steel , psi , tubing , zinc .
I hope this helps, trying to get individual fittings from ARB can be a PITA, not to mention
way over priced.
BTW, yes I am bored and I do need a life!
