TBE (Threaded Both Ends) nipples are the most widely used nipple type, featuring external threads on both ends with a plain unthreaded center section. Manufactured from black carbon steel to ASTM A733 standards, they are used across plumbing, fire protection, oil & gas, and industrial systems. Available in a wide range of sizes and thread standards including NPT, BSP, and BSPT.

A TBE pipe nipple, short for Threaded Both Ends pipe nipple, is a standard type of threaded pipe nipple.
Both threaded ends, while the center section remains plain, to ensure stable tightening.
TBE pipe nipples provide a clear center section, making them more practical for assembly with threaded fittings.
Our galvanized steel nipples have an electro-dipped surface, providing enhanced corrosion resistance.
As a China galvanized pipe nipples manufacturer, our products meet ASTM standards, NPT, BSP, and BSPT threads.
