ST-41 22mm x 1/4"MPT S.S. SCREW PLUG 5800 PSI

SKU: 6840

A stainless-steel ST-41 screw plug with a 1/4-inch male pipe thread outlet, rated 5,800 PSI. Choose the MPT version when the downstream component has a female port — it threads straight in with no additional adapter. Suttner rates the brass ST-41 family at 5,800 PSI and 300 degrees F maximum; match those limits to your machine before ordering. 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.
