Galvanized Iron (GI) Union – Durable Plumbing Pipe Connector

Introduction

A Galvanized Iron (GI) Union is a vital plumbing fitting designed to connect two pipes while allowing easy disconnection for maintenance or repairs. Unlike fixed fittings, a GI Union enables plumbers and engineers to assemble or disassemble pipelines without cutting or damaging the pipes.

At Tapmaster Kenya, we supply premium GI Unions that combine durability, corrosion resistance, and reliable performance for residential, commercial, and industrial plumbing systems.

What Is a GI Union?

A GI Union is a three-piece fitting that joins two pipes and includes a central nut that holds the connection together. This design allows the pipes to be disconnected quickly for repairs, maintenance, or system modifications.

Material & Features:

Material: High-grade galvanized iron
Coating: Zinc galvanization for corrosion protection
Thread Type: Standard BSP male/female threads
Design: Leak-proof and reusable for maintenance access

The zinc coating protects the union from rust, making it ideal for both indoor and outdoor plumbing applications.

Key Features of GI Unions

✅ Durable Construction: Made from heavy-duty galvanized iron for long-lasting use.
✅ Corrosion-Resistant: Zinc coating prevents rust and ensures long life.
✅ Reusable Design: Can be disassembled and reassembled without damaging pipes.
✅ Leak-Proof: Provides secure connections in water, gas, or air systems.
✅ Easy Installation: Compatible with standard threaded pipes and fittings.

Applications of GI Unions

GI Unions are used in various plumbing systems:

Domestic plumbing for connecting pipes while allowing easy maintenance.
Industrial piping systems carrying water, gas, or compressed air.
Irrigation and agricultural setups requiring flexible connections.
Construction projects where frequent maintenance or modifications are expected.

Their disassemblable design makes them perfect for systems that require occasional inspection or repair.

Leak Prevention: Ensures tight and secure connections.
