Brass Reducing Coupling 10 Pack

This pack contains ten brass reducing couplings built to Class 150 specification. Each fitting joins a 1/4 in Female NPT thread to an 1/8 in Female NPT thread. The brass construction resists corrosion in water and air lines. Plumbers and maintenance technicians use them to step down pipe sizes in residential and light commercial systems.

Replaces Mismatched Bushings

The coupling replaces improvised assemblies that combine separate bushings and nipples. Using a single purpose made fitting reduces potential leak paths and cuts installation time. The jump is worth it when a clean, code compliant reduction is required and when future disassembly must remain straightforward.

Simple Threaded Installation

Apply thread sealant to the male threads, then tighten each end to the recommended torque for the pipe material. The most common issue is over tightening brass into harder metals, which can split the female ports. Another frequent error is mixing NPT with other thread standards, which prevents a proper seal.
