IMPORTANT SIZING NOTE - Most plumbing products are measured using BSP thread dimensions which measure 1/4 inch larger than that stated, therefore this 1/2 Inch BSP thread actually measures 3/4 Inch in diameter. If your thread measures 1/2 Inch in diameter then you require the 1/4 Inch version of this product This listing is for a Pack of 1 Screws directly into unused female ports on manifolds, boiler casings, radiators, pumps, and pipe fittings to create a flush, pressure-tight end point that stops leaks and blocks debris. Unlike female caps or extended stop ends, a plug sits mostly inside the female socket, leaving only the hex head or square drive exposed—making it ideal for tight spaces and recessed manifold blocks.
