Standard Galvanized Iron GI Plug 1/2 Inch, Threaded BSP

Galvanized Iron GI Plug

The Standard Galvanized Iron GI Plug 1/2 Inch provides a high-pressure seal for terminating pipe runs in residential, commercial, and industrial plumbing systems. This fitting features a heavy-duty malleable iron construction that withstands mechanical stress and thermal expansion. It is designed for compatibility with standard 15mm threaded pipes and manifold ports.

Built for the Job

Plumbers and site supervisors utilize this component to cap off water supply lines, gas conduits, and steam systems during both construction and maintenance phases. The hot-dip galvanized finish ensures the fitting resists oxidation when exposed to moisture or corrosive environments. This durability makes it a staple for outdoor irrigation setups and internal riser installations where longevity is non-negotiable. The robust thread profile allows for multiple installations and removals during pressure testing without stripping the grooves.

• Sealing unused outlets in galvanized steel manifolds and distribution headers.

• Temporary capping of water lines during building renovation projects.

• Permanent closure of drain points in low-pressure steam or air systems.

Product Highlights

Corrosion Resistance

The hot-dip galvanizing process creates a metallurgical bond between the zinc and the iron to prevent rust formation.

Square Head Design

• Provides a secure grip for pipe wrenches and adjustable spanners.
• Allows for high-torque application to ensure a leak-proof mechanical seal.
