Air Coupler 1/4in 5-in-1 Universal Safety Exhaust Quick Connect

A 5 in 1 universal air hose coupler for connecting compressed air tools and hoses across different plug types. The quick connect design makes airline changes simpler, while the built-in safety exhaust helps release pressure before disconnecting.

Used in garages, workshops and general compressed air setups, this coupler is handy when different air tools or existing hose fittings are already in use. It suits vehicle maintenance, servicing, DIY repairs and trade use where you want to swap between tools without stopping to change couplers. For mixed airline systems, it helps cut down the usual hassle of matching the right fitting each time.

The coupler accepts several common interchange standards, making it a practical option where more than one plug style is in circulation. A 1/4in BSP male thread gives a straightforward connection into an existing airline setup, and the 300 PSI maximum working pressure suits typical workshop air systems. The safety exhaust function bleeds off air before full release, helping make disconnection more controlled. That also makes it useful for regular maintenance where tools and hoses are connected and removed repeatedly through the day.
