Product Questions & Answers

does this nut work with half inch tube OD or is it sized different than that

Question by: Tommy R on Aug 12, 2025, 7:27 AM

Half-inch tube OD is exactly what this nut is built for. The 0.50-inch tube OD spec is the whole point of this part, so if your air brake line matches that dimension, you're in good shape. No flaring or tube prep required either, which makes getting it on the line a lot more straightforward than some other fittings out there.

got a half inch OD air brake line, is this the right nut for it or am i mixing sizes

Question by: Sherry W on Mar 14, 2026, 9:42 PM

For a 0.50 inch tube OD, this spare part nut is the correct size match. It is part of the 1461x series and is intended for use with NT100 Nylon Tubing that meets SAE J844 Type A and B.
