Galvanized Nipples
A galvanized nipple is a short zinc-coated cast fitting with male threads on both ends that connects two female-threaded parts. In water lines it connects equipment such as valves, meters and filters to fittings without using pipe.
It is used in water meter groups, valve and check valve arrays, booster set and irrigation valve connections. It is supplied in 11 sizes from 1/4″ to 4″ and with a reducing nipple option.
Main Applications
- Valve groups before and after water meters
- Valve, check valve and strainer arrays
- Booster set and pump connections
- Irrigation valve and filter connections
- Equipment connections in sprinkler lines
- Valve arrays on manifolds

How to Choose?
- Measure the female threadsDetermine the female thread size of both parts; if they differ, choose a reducing nipple.
- Assess the distanceUse a nipple for short distances and a threaded pipe piece for longer ones.
- Confirm the mediumPrefer galvanized nipples for fresh water lines and black nipples for closed heating.
- Plan the sealingChoose a thread sealing material suitable for drinking water.
