Value Collection 13383 3/4 Inch Malleable Iron Hex Plug

Product Description

The VALUE COLLECTION 13383 is a malleable iron countersunk hex plug designed to cap and seal threaded pipe ends in plumbing, HVAC, and industrial piping systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting handles a wide range of pressure and temperature conditions. The countersunk hex drive allows installation with a standard hex key or socket rather than a wrench on exposed flats, making it useful in tight or flush-mount applications. Licensed plumbers and pipefitters install this type of plug during system testing, capping unused outlets, or completing final rough-in work.

This plug fits 3/4 inch threaded pipe and is suited for residential and light commercial piping systems carrying water, gas, or steam. The countersunk hex head sits below the fitting face when installed, providing a low-profile seal. It is commonly used in gas distribution headers, hydronic heating systems, compressed air lines, and general plumbing rough-in where a flush or recessed cap is preferred over a standard square-head plug. Each order includes 5 pieces.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements. Shut off all fluid, gas, or steam supply and relieve system pressure completely before installing or removing any threaded pipe plug. Apply thread sealant or PTFE tape appropriate for the service medium before threading the plug into the fitting. Use a properly sized hex key or socket driver and avoid overtightening, which can crack the fitting or damage threads.
