Ground Joint Female Spud 3/4" NPT – Plated Steel

The Boss® Ground Joint Female Spud is a key component in high-performance hose coupling systems, designed for use in steam, air, water, petroleum-based fluids, and chemical transfer applications. This 3/4" NPT female spud is made of plated steel, offering enhanced corrosion resistance and long-lasting durability in industrial environments.

This spud is intended to be threaded onto fixed piping or equipment and paired with a ground joint stem on a hose end. Together with a wing nut, the two components create a secure, pressure-tight metal-to-polymer seat seal that prevents leaks and withstands vibration and thermal expansion.

The design allows for frequent connection and disconnection without compromising safety or efficiency. The polymer seat ensures superior sealing performance and protects against galling, making it suitable for repetitive use. Its wide compatibility with rubber, synthetic, plastic, or metal hoses adds to its versatility on job sites and in plant operations.
