<h3>About Brass Fittings by Midland Industries</h3><p>When it comes to reliable fluid and gas transfer, the quality of your fittings matters as much as the quality of your pipe or hose. <strong>Brass Fittings</strong> — rooted in the Jamnagar manufacturing tradition and distributed through Midland Industries — represents a benchmark in precision-engineered connection hardware for industrial, automotive, plumbing, and outdoor equipment applications.</p><p>Jamnagar, India, has long been recognized as one of the world's premier centers for brass component manufacturing, and this brand draws on that deep metallurgical expertise. Using state-of-the-art CNC machinery and rigorous quality control practices, Brass Fittings produces components that meet demanding dimensional tolerances and pressure ratings across a wide range of thread standards — including NPT, NPTF, BSP, and metric — making them compatible with both domestic and international systems.</p><h3>A Comprehensive Fittings Lineup</h3><p>The core of the catalog is an extensive range of <a href="/7273-brass-fittings-pipe-fitting-17358">pipe fittings</a>, encompassing elbows, tees, unions, couplings, bushings, nipples, caps, and crosses in a variety of sizes and configurations. These are the workhorses of any plumbing, pneumatic, or hydraulic system — connecting runs of pipe securely while maintaining leak-free performance under pressure.</p><p>For applications where both pipe and hose connections are needed in the same system, the brand&apos;s <a href="/7273-brass-fittings-brass-bronze-pipe-hose-fittings-201742">brass and bronze pipe &amp; hose fittings</a> offer versatility and corrosion resistance in a single product family. Bronze alloys are particularly valued in marine, chemical, and high-humidity environments where dezincification resistance is critical. Whether you need hose barbs, flare fittings, compression fittings, or forged adapters, this lineup covers the full spectrum of connection styles.</p><p>Recognizing that not every application calls for metal, Brass Fittings also offers a selection of <a href="/7273-brass-fittings-nylon-pipe-hose-fittings-200724">nylon pipe &amp; hose fittings</a> designed for lighter-duty fluid transfer needs. Nylon fittings are a smart choice where chemical compatibility, weight savings, or electrical non-conductivity are priorities — common requirements in automotive fuel systems, agricultural equipment, and marine auxiliary systems.</p><h3>Why Choose Brass Fittings?</h3><ul><li><strong>Material quality:</strong> Free-cutting brass alloys (such as IS 319 / C36000) are used throughout, delivering excellent machinability and long service life.</li><li><strong>Wide thread compatibility:</strong> NPT, NPTF, BSP, metric, and other thread forms are available to suit virtually any system.</li><li><strong>Broad application range:</strong> Suitable for water, gas, oil, pneumatic, and hydraulic service across automotive, industrial, and residential settings.</li><li><strong>Finish options:</strong> Natural brass, nickel-plated, and tin-plated finishes are available depending on the environmental demands of the application.</li><li><strong>Extensive SKU depth:</strong> With hundreds of parts across multiple fitting types and sizes, it&apos;s easy to source everything needed for a single project from one brand.</li></ul><p>Whether you are maintaining a vehicle&apos;s fuel or coolant lines, plumbing a workshop compressor, or outfitting marine equipment, Brass Fittings delivers the precision and durability that professionals and serious DIYers depend on.</p>

Product Details

The Brass Fittings RB1238 is a hex bushing reducer designed to connect two pipes of different diameters. This fitting features 1/2-inch male NPT (National Pipe Taper) threads on the outside and 3/8-inch female NPT threads on the inside, allowing you to adapt from a larger to smaller pipe size in plumbing, air, and fluid transfer applications.

Key Features:

  • Durable brass construction for excellent corrosion resistance and longevity
  • 1/2" male NPT x 3/8" female NPT thread configuration
  • Hexagonal head design provides superior grip and torque when using a wrench
  • NPT tapered threads create tighter, more reliable seals than straight threads
  • Class 125 rating suitable for water, gas, oil, air, and steam applications
  • Precision-machined threads ensure proper fit and easy installation

This reducing bushing is ideal for marine, RV, plumbing, pneumatic, and general industrial applications where connecting different pipe sizes is required. The brass material offers excellent ductility at high temperatures and low magnetic permeability, making it versatile for various fluid transfer systems.
