Quick-Connect Coupler for Automotive Air Lines
The SPEEDAIRE 30E743 is a female-threaded coupler body built for 3/8"-18 NPT connections on air supply lines. It uses an automotive interchange profile compatible with Tru-Flate-Automotive fittings. The steel body suits workshop air systems that require tool-free hose changes.
Steel Construction with Zinc-Plated Finish
The body is made from steel with a zinc-plated coating for surface protection. A sleeve locking mechanism allows one-handed connection and disconnection without tools. An integrated nitrile seal and poppet-type valve control air flow and provide sealing within rated pressure and temperature limits.
3/8"-18 NPT Female Thread Determines Fit
This coupler only fits ports or fittings with a matching 3/8"-18 NPT male thread. It will not work with other thread standards, different nominal sizes or proprietary quick-connect profiles. Buyers needing a larger body size, a male thread or a different interchange standard must select another part.

Questions about this item
What thread standard does the 3/8 NPT female connection follow and what does it seal against?
The coupler uses a 3/8"-18 NPT female thread and an integrated nitrile seal to seal against compatible fluid or air lines within rated pressure and temperature limits.
What are the physical dimensions and material of the coupler body?
The body is 3/8 inch nominal diameter, constructed from steel with a zinc-plated finish for surface protection.
How do you install this quick-connect coupler and which step is often missed?
Thread the female 3/8"-18 NPT end onto the male fitting, then pull back the sleeve to insert the plug until it locks; the step often missed is fully seating the plug so the poppet valve opens completely.
