Description
Overview:
The Brass Lugged 3" BSP Female Thread Blanking Cap with Securing Chain (MPN 343 300) is a robust cap for sealing the ends of pipework, valves, and fittings with a 3" (76.2 mm) BSP male thread. Made from high-quality brass with a durable, corrosion-resistant finish, it helps prevent leaks and protects threads from damage and contamination when lines are out of service or under maintenance. The lugged body allows firm hand tightening and easy removal with common tools, while the supplied leather washer supports a tight, reliable seal. A fixed securing chain reduces the risk of misplacement. Suitable for a wide range of plant, plumbing, and industrial systems, including pumps, manifolds, and tanks often found on construction sites and in workshops.
