Value Brand Steel Union 1 in NPT Class 3000

SKU CH-B82N-XB2N9

A 1-inch NPT steel union rated Class 3000 for Schedule 160 piping systems

  • Steel A105 construction resists corrosion in demanding piping systems
  • Class 3000 rating handles high-pressure applications up to schedule 160
  • 1 inch NPT threads connect directly to standard pipe fittings
  • Galvanised finish protects against rust for extended service life
  • Female threaded ends allow quick assembly without welding

1-Inch NPT Steel Union

This forged-steel union connects two 1-inch NPT threaded pipes in a straight line. The galvanised A105 body meets Class 3000 pressure rating for Schedule 160 piping systems. Both ends are female threaded with 11.5 threads per inch. The fitting is supplied new and ready for installation.

Suited for high-pressure pipe joins

Installers joining Schedule 160 pipe at Class 3000 rating will find the correct thread form and material here. The union allows easy disassembly for maintenance without cutting pipe. Buyers needing a different nominal size, a welded connection or a lower pressure class should select another fitting.

Class 3000 pressure rating

The Class 3000 designation confirms the fitting is manufactured for Schedule 160 service. This single rating determines whether the union matches the design pressure of the piping system. Verify the system pressure class before purchase.

Questions about this item

Which size and class of steel union matches my 1-inch Schedule 160 piping?

The 1-inch NPT union is rated Class 3000 and built for Schedule 160 pipe, so it matches that exact size and pressure class.

What does the Class 3000 rating mean when the union is installed in a live system?

Class 3000 indicates the design pressure envelope for galvanized A105 steel at standard temperatures; actual working pressure depends on temperature, fluid and applicable piping code.

How do the 11.5 threads per inch on the NPT ends affect sealing and compatibility?

The 11.5 TPI NPT threads create a tapered seal when tightened with proper sealant, and they mate only with other 1-inch NPT fittings — not with BSPT or straight-thread ports.
