1 1/2 Inch Brass Threaded Flanged Plug – BSP Blanking Bung

1 1/2 Inch Brass Threaded Flanged Plug – BSP Blanking Bung

Features

The 1 1/2 inch brass threaded flanged plug provides a heavy-duty blanking solution designed to securely seal off unused 1 1/2 inch BSP female threaded ports, pipes, or manifolds. Built from solid, premium brass construction, it delivers exceptional strength, corrosion resistance, and long-term durability in both domestic and commercial plumbing applications. Furthermore, it features a convenient flanged head design that allows for easy tightening with standard spanners while preventing the plug from over-inserting into the fitting. Because it is machined to exact standard sizing with a 1.5-inch thread measuring 48mm in diameter, it ensures a precise, reliable fit when paired with a suitable sealing tape, compound, or washer.

• Solid Brass Construction: Manufactured from high-grade, heavy-duty brass. Therefore, it provides excellent resistance to corrosion, rust, and high temperatures.
• Precise 1 1/2″ BSP Thread: Engineered with a standard 1.5-inch thread diameter measuring approximately 48mm. Consequently, it screws smoothly into compatible female BSP fittings.
• Convenient Flanged Head: Features an integrated flat-faced flange edge. Moreover, it allows you to grip and torque the plug securely with a standard wrench while preventing over-tightening.
• Versatile Blanking Solution: Designed specifically to seal off spare ports on manifolds, valves, tanks, and pipe runs. As a result, it helps you manage custom plumbing layouts efficiently.
• Reliable Pressure Sealing: Forms a rock-solid mechanical stop when combined with traditional plumbing tape, jointing compound, or a matching washer. Furthermore, it ensures a completely leak-free seal under normal operating pressures.

Details

Leaving spare ports, unused manifold branches, or open pipe ends unsealed can lead to major water leaks, system pressure drops, and contamination in your plumbing network. Moreover, using low-quality plastic or poorly machined plugs often results in stripped threads and stubborn leaks that are difficult to fix.

Fortunately, this solid brass 1 1/2-inch flanged plug solves the problem completely. Because its precision-cut 48mm BSP threads and sturdy brass body screw securely into any standard 1.5-inch female port, it creates an impenetrable barrier. Consequently, you achieve a professional, long-lasting, and leak-free seal for your entire plumbing system.
