ST-41 22mm x 1/2" FPT SCREW PLUG

SKU: 4640

This ST-41 screw plug adapts 22mm to 1/2-inch female pipe thread: the plug end carries the M22 x 1.5 metric thread that mates with a Suttner ST-41 coupler, while the 1/2-inch FPT end accepts a male-threaded American hose or accessory. European pressure washer guns commonly ship with 22mm outlets while American hoses and accessories use NPT, so this adapter plug is the standard bridge between the two systems. The 22mm screw connection is Suttner's metric standard: the plug half carries exposed M22 x 1.5 threads and locks into the ST-41 coupler half (the black-knob side) with a twist, a joint that resists vibration loosening better than a friction quick-connect.
