304SS HEX HEAD PLUG 1/2 MPT 150#

SKU: 5219

A 1/2-inch MPT hex-head pipe plug in 304 stainless steel, marked 150#. The ‘150#’ denotes Class 150 threaded stainless fittings per ISO 4144, with a maximum working pressure around 300 PSI — these are low-pressure fittings for water, oil, and gas service, and must not be used on the high-pressure outlet side of a pressure washer. The 304 stainless body resists corrosion from water, heat, and minerals, and the hex head takes a standard wrench. Seal tapered pipe threads with PTFE tape or pipe thread compound, and do not overtighten. Listed as SKU 5219.
