Galvanized Iron (GI) Hex Nipple – Strong and Reliable Pipe Connector

🔧 Introduction — What is a GI Hex Nipple?

A Galvanized Iron (GI) Hex Nipple is a short length of pipe with male threads on both ends and a hexagonal section in the middle that allows tightening with a wrench. It is used to connect two female-threaded fittings or pipes, making it a vital part of any plumbing or piping system.

At TapMaster Kenya, we supply premium-quality GI Hex Nipples designed for durability, corrosion resistance, and strength. Whether for domestic, industrial, or agricultural plumbing applications, our GI Hex Nipples deliver dependable performance and leak-free connections.

🧱 What is a GI Hex Nipple Made Of?

Material Composition & Design:

• Base Material: Malleable cast iron
• Coating: Hot-dip galvanized zinc
• Thread Type: BSP (British Standard Pipe) male threads
• Feature: Hexagonal center for wrench grip
• Finish: Smooth silver-grey zinc finish
