Value Brand 1-1/4" MNPT x 1" FNPT Galvanized Hex Bushing

SKU CH-JWGX-1BV3J

Connects 1-1/4" male NPT to 1" female NPT in galvanized steel for Schedule 160 piping

  • Reduces pipe size with 1-1/4" male to 1" female NPT threads
  • Galvanized steel resists corrosion in water and air systems
  • Hex body allows secure installation with standard wrenches
  • Class 3000 rating suits high-pressure Schedule 160 piping
  • Prop 65 warning notes chemical risk for California compliance

Product Identity

This galvanized steel hex bushing connects a 1-1/4 inch male NPT thread to a 1 inch female NPT thread. It is designed for plumbers and maintenance technicians joining dissimilar pipe sizes in high-pressure piping systems.

Sustained Load Behaviour

The Class 3000 rating supports continuous operation at elevated pressures without deformation. A105 steel construction resists mechanical stress and corrosion over long service intervals in Schedule 160 installations.

Decisive Specification

The 11.5 threads per inch on both male and female ends determine compatibility with existing NPT pipework. Buyers needing a different thread pitch or a non-threaded connection cannot use this fitting.

Questions about this item

How much heat does the galvanized steel generate when water flows through it continuously?

The steel fitting itself produces no heat; fluid temperature depends on the system, not the bushing.

What pipe schedule and thread standard must the existing piping match for this 1-1/4" MNPT x 1" FNPT bushing to seal correctly?

It requires Schedule 160 pipe with 11.5 threads per inch on both the 1-1/4" male and 1" female NPT ends.

Will this Class 3000 A105 hex bushing handle the pressure from my older steel pipework?

Yes, the Class 3000 rating suits high-pressure steel systems, and the galvanized A105 material matches legacy galvanized piping.
