Ground Joint Coupling for Steam Service

The ZORO SELECT 3LZ38 is a ground joint coupling designed for steam service applications. It connects hoses with a 1 inch interior diameter using a female NPT spud. The set includes a hose shank stem, female thread wing nut, male wing nut thread, and the spud itself. It suits maintenance teams and plant operators needing reliable steam connections.

Temperature Limit and Thread Standard

This coupling handles temperatures up to 450 degrees Fahrenheit, marking its practical ceiling for steam use. The wing nut uses a 1 inch NPT thread type, defining the pipe compatibility. Carbon steel construction on both spud and stem sets the material boundary for corrosion resistance and mechanical strength. No other thread standards or temperature ratings apply.

One Inch Capacity and Component Set

The 1 inch hose I.D. and matching pipe size determine the flow capacity for steam lines of that dimension. The included stem, wing nuts, and spud provide a complete assembly for immediate installation. It runs out when systems demand a different hose bore, a higher temperature rating, or a thread standard other than NPT.
