We manufacture a variety of plugs such as square head plugs, inside hex plugs, outside hex plugs, hex socket plugs, square socket plugs and slotted headless plugs. These pipe plugs are designed to insert into the end of tubing to dead-end the flow. These pipe plugs come in BSPP, BSPT, BSW, NPT & NPTF threads for connection to any regularly threaded pipe and are available in brass gunmetal and other alloys with nickel, chrome and other electroplating options.
