STEEL HEX HEAD PLUG 1/4 MPT, 5000 PSI

SKU: 3351

A 1/4-inch MPT hex-head pipe plug in carbon steel, listed at 5,000 PSI. Steel handles high-pressure service that would exceed brass or low-class fittings, but it is less corrosion-resistant than stainless — protect it from standing moisture and harsh chemicals. The hex head takes a standard wrench or socket for positive tightening into pump, unloader, manifold, or hose-reel ports. Seal tapered pipe threads with PTFE tape or pipe thread compound, and do not overtighten. Listed as SKU 3351.
