How to choose
- Match the interchange: the coupler and plug must be the same style — industrial (M-style), automotive (T-style/Tru-Flate) or ARO 210. Mixed styles leak or won’t lock. Universal couplers accept several plug styles.
- Body size: 1/4 in. body is the common size for most air tools; 3/8 in. body flows more air for high-demand tools.
- End connection: choose male or female NPT for threaded drops and tools, or hose barb / push-on ends to fit the hose ID directly.
- Material: steel plugs are hard-wearing for daily plant use; brass resists corrosion and won’t spark as easily.
- Standardize: pick one interchange for the whole plant and buy plugs in bulk for every tool so any hose fits any tool.
