Value Brand

Value Brand Hex Bushing 1 in x 1/2 in Class 150

SKU CH-JYCQ-PKSYJ

A malleable iron Class 150 hex bushing reducing 1 inch female NPT to 1/2 inch male NPT

  • Malleable iron construction resists corrosion
  • Class 150 rating handles standard pressure systems
  • 1 inch female NPT connects to larger pipes
  • 1/2 inch male NPT reduces to smaller lines
  • Hex design allows easy installation with standard wrenches

What this fitting is and who needs it

This hex bushing connects a 1 inch female NPT thread to a 1/2 inch male NPT thread. It is made from malleable iron rated for Class 150 service. Plumbers and maintenance technicians use it to reduce pipe size in water, air or gas lines where these thread dimensions match.

What the Class 150 rating changes

The Class 150 designation sets the pressure boundary for the fitting at the temperatures covered by that standard. It tells the installer the maximum non‑shock working pressure the bushing can handle in the intended piping system. Selecting a different class would change that pressure limit.

Practical limits of the NPT interface

National Pipe Taper threads seal by thread interference and require sealant or tape to prevent leaks. The 11 1/2 and 14 thread counts are fixed by the NPT standard for these nominal sizes. The taper angle and engagement length are also defined by that standard, so the joint cannot be tightened beyond the specified engagement without risk of cracking the iron.

Questions about this item

Does the malleable iron hex bushing need periodic replacement or maintenance after installation?

Malleable iron fittings are designed for permanent installation and do not require scheduled maintenance or replacement under normal service conditions.

What pressure limit applies to this Class 150 bushing during continuous operation?

The Class 150 rating defines the maximum allowable working pressure for sustained use in the piping system.

How much heat or noise does the fitting generate when the system runs all day?

As a passive pipe fitting with no moving parts or electrical components, it produces no heat or noise during continuous operation.
