Q: Can this coupler connect to automotive (T-style) plugs?
A: Yes — the S-1751 supports all five major coupling standards including T-style, so it works with automotive style plugs as well as industrial, ARO, Lincoln, and high flow types.

Q: What is the pressure rating?
A: The maximum working pressure is 120 psi, which is typical for general air tool systems.

Q: How does the safety exhaust function work?
A: When you begin to disconnect the plug, a sleeve mechanism first vents the trapped air pressure to atmosphere before fully releasing the plug — reducing the risk of hose whip or blow-back.
