Product Description
The galvanized king nipple with NPT thread is a specialized pipe fitting designed to connect threaded
pipes with secure, leak-proof joints. Featuring a hexagonal center
section for easy installation with standard wrenches, this king
nipple combines the corrosion protection of hot-dip galvanizing
with the reliability of precision-machined NPT threads.
Manufactured from high-grade carbon steel and finished with a
durable zinc coating, our king nipples withstand harsh
environmental conditions while maintaining structural integrity.
Available in sizes from 1/8" to 4" NPT, these fittings are
engineered for long-term performance in commercial, industrial, and
municipal applications where corrosion resistance and durability
are paramount.
