Midland Industries 28220 Reducing Hex Pipe Nipple Brass

Product Description

The MIDLAND INDUSTRIES 28220 is a reducing hex pipe nipple designed to connect two male NPTF threaded pipe ends of different sizes. It steps down from a 1/4-inch Male NPTF connection to a 1/8-inch Male NPTF connection, with a 1/4-18 x 1/8-27 thread specification. Constructed from brass, the fitting measures 1.19 inches in length with a 0.56-inch hex profile for wrench engagement. It is rated to 1200 psi and handles temperatures from -65 to 250 degrees F. Plumbers, HVAC technicians, and pipefitters install this type of fitting when transitioning between two different male-threaded pipe diameters in pressurized systems.

This fitting is suited for use in residential and light commercial plumbing, HVAC, and gas-line applications where a compact reducing connection is required between male-threaded pipe ends. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on sealant. Compatible pipe materials include aluminum, brass, bronze, copper, iron, and steel pipe, making it a versatile fitting across a range of system types and installation environments.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians. Depressurize and isolate the system before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the NPTF threads as required by the application and local code. Use a properly sized wrench on the hex body to avoid overtightening, which can crack brass fittings or distort the thread seal.
