Brass Fittings

<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 RB3814 is a white nylon hex reducer bushing designed for connecting pipes of different diameters. This fitting features 3/8" male NPT (National Pipe Taper) threads on one end and 1/4" female NPT threads on the other, allowing for secure connections between different sized threaded pipes or fittings.

Key Features:

  • White nylon construction offers excellent chemical resistance and durability
  • 3/8" MPT x 1/4" FPT threaded connections for versatile pipe sizing
  • Hexagonal head design provides increased bearing surface for easy installation with a wrench
  • NPT threads create a tight, reliable seal
  • Lightweight and corrosion-resistant material

This reducer bushing is commonly used in agricultural spraying systems, chemical transfer applications, and general plumbing where a transition from 3/8" to 1/4" pipe is needed. The nylon material makes it suitable for use with various chemicals, fertilizers, and water-based applications.
