Brass Fittings

<h3>About Brass Fittings</h3><p>When a connection needs to hold — whether in a plumbing system, an engine bay, a fuel line, or a marine application — the material and craftsmanship of the fitting matter enormously. Brass Fittings has built its reputation on exactly that principle: delivering precision-engineered components made from high-quality brass and bronze alloys that stand up to pressure, vibration, and corrosion over the long haul.</p><p>Rooted in the manufacturing tradition of Jamnagar, India — a region recognized globally as a hub for world-class brass component production — and distributed through the established network of Midland Industries, this brand brings together old-world metallurgical expertise and modern machining precision. The result is a broad catalog of fittings, adapters, and accessories trusted by professionals across automotive, industrial, marine, and residential applications.</p><h3>Why Brass and Bronze?</h3><p>Brass and bronze alloys offer a compelling combination of properties that make them ideal for fluid and gas handling systems. They resist corrosion far better than plain steel, machine cleanly to tight tolerances, and create leak-free seals when properly installed. Unlike plastic alternatives, brass and bronze fittings can handle elevated temperatures and higher working pressures, making them the preferred choice in demanding environments.</p><p>At the heart of the Brass Fittings lineup are the brand&apos;s <a href="/7273-brass-fittings-brass-bronze-pipe-hose-fittings-200203">Brass &amp; Bronze Pipe &amp; Hose Fittings</a> — a comprehensive assortment of elbows, tees, couplings, nipples, crosses, adapters, and barbed connectors. Whether you&apos;re routing coolant lines, building a fuel system, or plumbing a compressor, these fittings offer the dimensional consistency and thread quality needed to ensure a proper seal every time.</p><h3>A Complete Fittings Solution</h3><p>Beyond the core brass and bronze lineup, the catalog extends into <a href="/7273-brass-fittings-pipe-fitting-17358">Pipe Fittings</a> that cover a wide range of thread types, configurations, and material grades — giving technicians and builders the flexibility to tackle both standard and specialized installations. From straight pipe nipples to reducing bushings and hex plugs, these components are the backbone of any fluid-routing system.</p><p>No fitting installation is complete without a proper seal on the threads. Brass Fittings addresses this with <a href="/7273-brass-fittings-thread-sealant-tape-17329">Thread Sealant Tape</a> — the go-to solution for creating leak-tight connections on tapered pipe threads. Using the right thread sealant alongside quality brass fittings is a small step that makes a significant difference in long-term reliability.</p><p>Rounding out the lineup are <a href="/7273-brass-fittings-nylon-pipe-to-hose-adapters-200725">Nylon Pipe to Hose Adapters</a>, which bridge the gap between rigid pipe systems and flexible hose runs. These lightweight, corrosion-resistant adapters are particularly useful in applications where dissimilar materials need to be joined cleanly and securely.</p><h3>Built for Professionals and DIYers Alike</h3><p>Whether you&apos;re a professional mechanic, a marine technician, an HVAC installer, or a dedicated DIYer, the Brass Fittings catalog offers the components needed to do the job right. The combination of proven alloy materials, precise machining, and a broad range of configurations makes this brand a reliable one-stop resource for connection hardware across virtually any system.</p>

Product Details

The Brass Fittings RB112100 is a hex reducing bushing designed to connect pipes of different diameters in plumbing, pneumatic, and industrial applications. This fitting features 1-1/2 inch male NPT threads on the larger end and 1 inch female NPT threads on the smaller end, creating a secure, pressure-tight seal when properly installed.

Key Features:

  • Durable brass construction provides excellent corrosion resistance and longevity
  • Hexagonal head design allows for easy wrench application and secure installation
  • Male NPT threads (1-1/2") to female NPT threads (1") for step-down pipe connections
  • Suitable for water, oil, gas, compressed air, and general industrial applications
  • Designed for reliable performance under variable pressures and temperatures
  • Manufactured to meet ANSI/ASME B1.20.1 NPT threading standards

This reducing bushing is ideal for residential and commercial plumbing systems, HVAC installations, compressed air lines, and mechanical systems requiring a reduction from 1-1/2 inch to 1 inch pipe size. The brass material ensures durability and resistance to dezincification under normal operating conditions. For best results, apply appropriate thread sealant such as PTFE tape or pipe joint compound to male threads before installation.
