Description

3/8" Male x 1/4" Male Brass Hexagon Nipple

Brief Overview

This brass hexagon nipple is a straightforward adapter fitting designed to connect two male-threaded components of different sizes in pneumatic and hydraulic systems. The 3/8" and 1/4" male threads allow you to join lines or equipment with mismatched port sizes, while the machined hexagonal body provides solid wrench flats for installation and removal. The brass construction offers corrosion resistance and durability in demanding shop environments. Consider pairing this with threaded male quick-connect couplings to expand your pneumatic connection options.
