SKU CH-9N0K-33A66

Galvanized steel hex bushing reduces 1" male NPT to 3/4" female NPT for Schedule 160 pipe at Class 3000 rating

  • Reduces pipe size from 1 in MNPT to 3/4 in FNPT for flexible plumbing connections
  • Galvanized steel construction with A105 material resists corrosion in water and gas lines
  • Class 3000 rating supports high-pressure applications up to demanding system requirements
  • Schedule 160 wall thickness provides extra strength for heavy-duty industrial use
  • Precision NPT threads (11.5 and 14 TPI) ensure leak-free sealed joints

1 in MNPT x 3/4 in FNPT Galvanized Hex Bushing

This galvanized steel hex bushing connects a 1 inch male NPT thread to a 3/4 inch female NPT thread. It is rated for Class 3000 service and Schedule 160 pipe. The fitting meets ASTM A105 material specifications for forged carbon steel piping components.

Replaces worn or mismatched threaded reducers

Use this bushing when a straight-threaded reduction is required between dissimilar pipe sizes in high-pressure systems. The Class 3000 rating supports demanding applications where standard fittings may not hold. The jump is worth it when system pressure or schedule demands exceed lighter-duty alternatives.

Suits plumbers and maintenance crews working

This fitting is not for installers needing push-to-connect, compression, or flanged connections. It does not suit systems requiring stainless steel, brass, or plastic construction. Buyers needing different thread standards or pressure classes should look at other configurations.

Questions about this item

What size male and female threads does this 1 in MNPT x 3/4 in FNPT galvanized hex bushing use?

It has a 1 in MNPT male end with 11.5 threads per inch and a 3/4 in FNPT female end with 14 threads per inch.

How do I install the hex bushing without damaging the galvanized coating?

Use a wrench on the hex flats only, apply PTFE tape or pipe dope to the male threads, and tighten to the recommended torque for Schedule 160 pipe.

Will the galvanized finish hold up to the Class 3000 pressure rating over time?

The A105 steel body is rated for Class 3000 service; inspect threads periodically for corrosion or white rust and replace the fitting if the coating is breached.
