Female Quick Release 'Snap' Coupling ¼"

An essential ¼" BSP threaded air line connecting component. It screws onto your air compressors outlet (or its' filter / regulator outlet) to facilitate a quick, secure and virtually air-tight connection between the air tool & air hose (when, of course, the hose fitted with a suitably BSP threaded snap coupling) to establishes a secure, positive and quick to use connection to the air line.
