The Brass Lugged 2.1/2" BSP Female Thread Blanking Cap with Securing Chain (MPN 343 250) is a heavy-duty cap for sealing and protecting male BSP threaded outlets. Made from solid brass for good corrosion resistance, it provides a reliable temporary closure to help prevent leaks and keep dirt, dust, and moisture out of pipework and equipment.
