  • Galvanized steel resists corrosion for long service life
  • Class 300 rating handles up to 1500 psi at 150°F
  • Reduces 2-inch male thread to 1-1/4-inch female thread
  • Hex design allows secure installation with standard wrenches
  • Meets ASME B16.3 and ASTM A197 quality standards

Galvanized Hex Bushing 2" x 1-1/4

This galvanized steel hex bushing connects a 2-inch male NPT thread to a 1-1/4-inch female NPT thread. It is built for plumbing and industrial piping systems that require a durable, corrosion-resistant transition between different pipe sizes. The fitting meets ASME 16.3 and ASTM A-197 standards for material quality and dimensional accuracy. It suits installers who need a reliable reducer for water, oil, or gas lines.

Class 300 pressure rating and temperature limits

Rated for 1500 psi at 150 degrees Fahrenheit WOG and 300 psi for saturated steam, the bushing handles high-pressure fluid and steam service within Class 300 limits. The operating temperature range spans from -20 degrees to 150 degrees Fahrenheit. It is not suited for applications exceeding these pressure or temperature boundaries or for cryogenic service below -20 degrees Fahrenheit.

Hex profile and galvanized construction

The hexagonal exterior allows tightening with a standard wrench, providing secure engagement without damaging the fitting. Galvanized steel construction resists rust in damp or outdoor environments. With an outside diameter of 2 1/2 inches and two bolt holes, the fitting supports stable mounting where required. The NPT taper threads create a seal with thread tape or compound, so no separate gasket is needed.

Questions about this item

Will the 2" MNPT x 1-1/4" FNPT threads on this galvanized hex bushing match my existing Class 300 steel piping?

Yes, the bushing is built to ASME 16.3 and ASTM A-197 with a Class 300 rating, so the 2" male and 1-1/4" female NPT threads align with standard Class 300 galvanized steel pipe.

How can I verify the fitting is holding pressure after installation?

Pressurise the line up to the 1500 psi WOG rating at 150 °F, or 300 psi for saturated steam, and check for leaks at the 2-1/2" hex body and both thread joints.

Does the box include thread sealant or gaskets, or must I buy them separately?

Only the galvanized hex bushing is supplied; pipe thread sealant or PTFE tape for the NPT connections must be purchased separately.
