Terminology for 1/4" Quick Connect Air Couplers uses "industrial" and "automotive" labels common retail terms for two main styles of 1/4" NPT quick connects. They refer to the shape of the male plug (not the coupler itself), which determines compatibility.
Style Plug Tip Shape Coupler Sleeve Markings Common Colors Notes ----- -------------- ----------------------- ------------- ----- Industrial Outward bevel/ring (M-style) Two stripes Red Tighter seal; standard for tools; less leak-prone. Automotive Inward bevel (T-style/Tru-Flate) One stripe Blue Slightly looser fit; common in auto shops; may hiss if low-quality.
These are not interchangeable without adapters but can connect sometimes not well.
Industry Standards
Beyond retail names, manufacturers use standardized profiles (e.g., Milton, ARO) for catalogs and specs:
- Industrial: M-style (Type D/I/M), red, ~32 CFM flow.
- Automotive: T-style (Type C), blue, ~32 CFM flow.
- Others: A-style (ARO, green, ~28 CFM); V-style (high-flow, purple, ~70 CFM for HVLP).
