MTM Hydro Adapters are developed to convert one plug or coupler into another style of plug or coupler. This particular adapter has an M22 Twist Coupler (Black side) with 14mm stem converted into a standard 3/8" QC Plated Steel Plug. It can be found on Spray Gun inlets, Pump outlets, or even in conjunction with other adapters for a more complex change of fittings.
This item is commonly paired with the 24.0481 when converting a Sunjoe, AR, Ryobi or Greenworks machine into a QC setup at the gun-to-hose joint.
