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>

This adapter features a 3/4" male national pipe thread (MPT) on one end and a 1/2" barbed insert on the other, allowing you to connect flexible hoses or tubing to threaded pipe systems.

Key Features:

  • White nylon construction offers excellent chemical resistance and durability
  • FDA approved material safe for potable water and food-grade applications
  • 3/4" MPT (Male Pipe Thread) x 1/2" hose barb configuration
  • Barbed design creates secure grip on flexible hose or tubing
  • Lightweight yet strong plastic construction resists corrosion
  • Ideal for water, air, and chemical transfer applications

This versatile adapter is commonly used in pond systems, irrigation setups, sprayer equipment, and general plumbing applications where a threaded connection needs to interface with flexible tubing. The barbed end provides a secure mechanical grip that can be reinforced with a hose clamp for maximum leak prevention.
