STEEL ALLEN HEAD PLUG 3/8 MPT, 4000 PSI

SKU: 3353

A 3/8-inch MPT Allen-head pipe plug in carbon steel, listed at 4,000 PSI. It pairs the strength of steel for high-pressure service with a hex-socket head that sits low and near-flush where a standard hex head would interfere with guards or mounting. Steel is less corrosion-resistant than stainless, so keep it out of standing moisture and aggressive chemicals. Seal tapered pipe threads with PTFE tape or pipe thread compound, and do not overtighten. Listed as SKU 3353.
