Value Collection DXC.NSB Malleable Iron Pipe Bushing

Product Description

The VALUE COLLECTION DXC.NSB is a Class 150 malleable iron pipe bushing designed to reduce a 1/2-inch pipe fitting down to a 3/8-inch connection. Constructed from galvanized malleable iron, it delivers a pressure rating of 300 psi for liquid and gas service and 150 psi for steam service. This bushing is a standard threaded reducing fitting used in piping systems across HVAC, plumbing, and industrial gas applications. Licensed plumbers and pipefitters install this type of fitting during new construction and maintenance work where pipe diameter changes are required at a threaded connection point.

This fitting is suited for residential and light commercial piping systems carrying water, gas, or steam. It performs in applications such as gas supply lines, compressed air distribution, hot water heating systems, and general fluid conveyance where a threaded reducing connection is needed. The galvanized finish provides added corrosion resistance, making it appropriate for exposed or moderately humid environments. Its compact bushing profile allows it to thread directly into a female-threaded fitting or valve body without requiring a coupling or nipple in between.

Key Features

• Reduces 1/2-inch female thread to 3/8-inch male thread in a single fitting
• Rated at 300 psi for liquid and gas service
• Rated at 150 psi for steam service
• Class 150 malleable iron construction for ductility and impact resistance
• Galvanized finish for corrosion protection
• Compact bushing form installs directly into female-threaded openings

Compatibility

Designed as an OEM-style replacement or standard replacement fitting for Class 150 malleable iron threaded piping systems requiring a 1/2-inch to 3/8-inch reducing bushing.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code as relevant to the service medium. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded malleable iron fittings, as excessive torque can crack the fitting body.
