Description

Brass Pipe Reduction Bushing, 1/2-Inch GZ Male to 3/8-Inch GW Female

Brief Overview

This brass reduction bushing provides a straightforward solution for connecting larger 1/2-inch GZ male threads to smaller 3/8-inch GW female ports in pneumatic systems, air lines, or plumbing applications. The solid yellow-brass construction ensures corrosion resistance and long service life in both wet and dry environments. For distributors stocking pneumatic components, this reducer fills a critical gap in system assembly—pair it with quick-connect fittings and complementary male-to-female adapters to offer customers complete line-fitting solutions.

Key Features

  • Solid Brass Construction: Yellow-brass material resists corrosion and oxidation; suitable for compressed air, inert gases, and water lines
  • Male-to-Female Thread Design: 1/2-inch GZ (male) external threads; 3/8-inch GW (female) internal threads
  • Hexagonal Shoulder: Wrench flats enable tool-assisted tightening without slipping or thread stripping
  • Machined Precision: Concentric bore with evenly cut internal threads; chamfered edges reduce assembly friction
  • No Markings: Clean, unmarked surface ready for white-label packaging and resale under your brand

Business Advantages for Distributors

  • High-Demand Connector: Reduction fittings are constant stock items for pneumatic shops, maintenance crews, and OEM assembly lines
  • Bulk-Order Friendly: Compact size and light weight reduce shipping costs; stock multiple thread combinations economically
  • Repeat Sales: Fittings wear or require replacement; customers return regularly for restocking
  • Premium Margin: Solid brass commands better pricing than plated steel alternatives; perceived quality justifies higher wholesale cost
  • System Completeness: Bundle with reducer bushings in other sizes to position your catalog as a one-stop source for thread adapters
