Galvanized Iron (GI) Barrel Nipple

🔧 Introduction — What Is a GI Barrel Nipple?

A Galvanized Iron (GI) Barrel Nipple is a short length of pipe with male threads on both ends, used to connect two female-threaded fittings or extend pipe runs. It is made from malleable iron coated with zinc galvanization, which protects the fitting against rust and corrosion.

At TapMaster Kenya, we supply high-quality GI Barrel Nipples in various sizes for all your plumbing and piping projects — from domestic installations to commercial systems. Our fittings are tested, durable, and precisely threaded for leak-free performance.

💪 Key Benefits of GI Barrel Nipples

   The zinc galvanizing layer prevents rust, making it ideal for both indoor and outdoor plumbing.

   Malleable iron gives excellent tensile strength — built to withstand water pressure and mechanical stress.
3. Leak-Proof Connections:
   Precision threading ensures tight, secure joints between fittings and valves.
4. Easy Installation:
   The dual male-threaded design allows quick extension or joining of two fittings without welding or special tools.
5. Versatile Applications:
   Commonly used in water systems, irrigation, compressed air, and general plumbing setups.
