Macdonald Couplings

The MacDonald Bayonet coupling is the recognised industry standard in industrial connections that is quick, safe and reliable, and allows effortless separation without the risk of accidental disconnection.

 The range is uniquely designed for high pressure compressed air or inert gas.  These items are widely used in oil refineries, chemical plants for nitrogen service and the engineering industry.  They are also used with pneumatic tools and for fire hose reel service where safety is a prime concern.

The male coupling has a sliding sleeve and is available with Hose End (HM) Inside Thread (IM) and Outside Thread (OM).  The Female coupling is available with Hose End (HF), Inside Thread (IF) and Outside Thread (OF).  The locking head is universal to all sizes.
