Standard 3/4 Inch GI Plug, Galvanized Iron Threaded Fitting

3/4 Inch GI Plug

The Standard 3/4 Inch GI Plug provides a heavy-duty solution for sealing threaded pipe ends in high-pressure water and gas systems. This fitting utilizes hot-dip galvanized malleable iron to ensure long-term resistance against oxidation and mechanical wear. It integrates seamlessly into any 20mm nominal bore piping network requiring a secure, leak-proof termination.

Built for the Job

Plumbers and facility managers rely on this component for both permanent and temporary pipe closures. The solid square-head or hex-head design allows for high-torque application using a standard pipe wrench or adjustable spanner without rounding the edges. On industrial sites, these fittings serve as essential blockers for manifold ports or as temporary caps during system pressure testing. The structural integrity of malleable iron ensures the fitting does not crack under the stress of thermal expansion or high-vibration environments common in pump rooms.

• Terminating dead-end runs in domestic and commercial galvanized steel plumbing.

• Sealing inspection ports in irrigation manifolds and water storage tanks.

• Temporary capping of gas lines during building renovations or extensions.

Product Highlights

Corrosion Protection

The hot-dip galvanizing process creates a thick zinc layer that protects the underlying iron from rust.

Precision Machining

• BSP (British Standard Pipe) tapered threads ensure a tight mechanical seal.
• Uniform wall thickness prevents weak points under high-pressure conditions.

Technical Specifications

What’s Included

• 1 x 3/4 Inch Galvanized Iron Threaded Plug

On-Site & Workshop Notes

• Apply PTFE thread seal tape or pipe dope to the male threads to ensure a watertight connection.

• Avoid over-tightening into PVC or plastic female fittings to prevent stress fractures in the softer material.

• Store in a dry area to maintain the integrity of the zinc coating before installation.

• This iron component is suitable for use in systems carrying water, air, or non-corrosive gas.
