1" x 3/8" Hex Bushing

This malleable iron hex bushing connects a 1 inch female NPT thread to a 3/8 inch female NPT thread. It is rated for Class 150 service and carries 11 1/2 and 18 threads per inch on the respective ends. The fitting is new and ready for installation in compatible piping systems.

Build integration

The bushing threads directly into a 1 inch female NPT port and accepts a 3/8 inch male NPT component, reducing the connection size without additional adapters. Its hex profile allows tightening with a standard wrench, and the malleable iron construction suits Class 150 pressure requirements. No seals or gaskets are included with the fitting itself.

Ideal use cases

Suited for plumbers and maintenance technicians reducing a 1 inch NPT line to a 3/8 inch branch in water, air or oil systems rated to Class 150. Not intended for applications requiring a male-to-male or female-to-female configuration, higher pressure classes, or different thread standards such as BSPT or compression fittings.

Questions about this item

What pressure ceiling does the Class 150 rating impose on this hex bushing?

Class 150 sets the maximum working pressure at 150 psi for the malleable-iron body, so sustained service above that limit is outside the design envelope.

How much heat or noise does the bushing generate when fluid runs through it continuously?

The fitting itself produces no noise or heat; any temperature rise comes from the conveyed fluid and the pipe system, not from the bushing.

What pipe sizes and thread types must already be in place for this 1 in x 3/8 in NPT bushing to install?

You need a 1 in female NPT port and a 3/8 in male NPT pipe end, both cut to the standard 11 1/2 and 18 threads per inch respectively.
