AirComParts Industrial Series Quick Coupler, 1/4 in. to 1/2 in. Body
Two numbers decide whether a coupler works for you, and only one of them is the pipe thread. Body size is the first: it sets which plugs will click into it. Thread size is the second: it sets what the coupler screws onto. A 3/8 in. body coupler on 1/2 in. female pipe thread is a normal, useful part, and it is not the same thing as a 1/2 in. coupler.
Everything on this page is the Industrial series. Industrial bodies accept Industrial plugs. They will not mate with the Automotive series, which we stock separately.
Available combinations
- 1/4 in. body: 1/4 in. FNPT (S1054), 1/4 in. MNPT (S1051), 3/8 in. FNPT (S1909), 3/8 in. hose barb (S1082)

- 1/2 in. body: 3/8 in. FNPT (S1914), 3/8 in. MNPT (S1920), 1/2 in. FNPT (S1915), 1/2 in. MNPT (S1921)
Sizing up is not always an upgrade
A bigger body flows more air, which matters for grinders, sandblasters and anything with a long duty cycle. It also means every plug in the shop has to match. If your drawer is full of 1/4 in. Industrial plugs, putting a 3/8 in. body on the wall just creates a connection nobody can use. Standardise on one body size across the shop and keep the odd sizes in a labelled box.
Hose barb versions terminate a length of hose directly. The thread versions take a fitting, and on vibrating equipment a short whip hose between the coupler and the tool will outlast a rigid connection every time.
Industrial interchange air line quick couplers in 1/4 in., 3/8 in. and 1/2 in. body sizes, with male NPT, female NPT and hose barb connections for shop air drops, tool whips and compressor outlets.
