Brass Fittings

<h3>About Brass Fittings</h3><p>When it comes to dependable fluid and gas connections, few materials have stood the test of time like brass. <strong>Brass Fittings</strong> is a manufacturer rooted in the precision-machined components tradition of Jamnagar, India — a region globally recognized as a center of excellence for brass manufacturing. Combining state-of-the-art CNC machining with rigorous quality standards, Brass Fittings delivers components engineered for long-term reliability across plumbing, pneumatic, hydraulic, automotive, and industrial applications.</p><p>Brass as a material earns its reputation through an exceptional combination of properties: natural corrosion resistance, excellent machinability, high tensile strength, and the ability to form leak-free threaded connections. These qualities make brass fittings a go-to choice for professionals and enthusiasts alike, whether the job involves routing fuel lines, connecting air tool systems, or building out fluid transfer assemblies on a vehicle or equipment platform.</p><h3>A Broad Range of Connection Solutions</h3><p>The flagship category for this brand is <a href="/7273-brass-fittings-brass-bronze-pipe-hose-fittings-200203">Brass &amp; Bronze Pipe &amp; Hose Fittings</a> — an extensive lineup that spans elbows, tees, couplings, nipples, adapters, and unions in both standard and specialty configurations. Whether you need a simple street elbow to redirect a fuel line or a complex reducing fitting to transition between tube sizes, this range covers virtually every scenario encountered in automotive and equipment applications.</p><p>Complementing those fittings is a selection of <a href="/7273-brass-fittings-pipe-fitting-17358">Pipe Fittings</a> — the threaded connectors and nipples that form the backbone of any piping system. Proper pipe fittings ensure secure, pressure-rated joints whether you&apos;re plumbing an air compressor, a hydraulic circuit, or a coolant line. Brass&apos;s natural thread-forming properties make these fittings especially well-suited for repeated assembly and disassembly without galling or thread damage.</p><p>For every threaded connection, achieving a leak-free seal is paramount. <a href="/7273-brass-fittings-thread-sealant-tape-201063">Thread Sealant Tape</a> — commonly known as PTFE or pipe tape — works hand-in-hand with brass fittings to fill the microscopic gaps in threaded joints, preventing fluid and air leaks in even high-pressure systems. Having the right tape on hand is as important as the fitting itself.</p><p>The lineup also includes <a href="/7273-brass-fittings-nylon-pipe-to-hose-adapters-200725">Nylon Pipe to Hose Adapters</a>, a practical solution for transitioning between rigid pipe threads and flexible hose assemblies. These adapters are ideal in applications where vibration isolation or routing flexibility is needed, such as in engine compartments or equipment frames. Finally, the <a href="/48894-air-tool-hose-splicer-brass-fittings-7273">Air Tool Hose Splicer</a> selection rounds out the pneumatic accessories offering, allowing worn or damaged air hoses to be repaired in the field without replacing the entire line — a practical, cost-effective solution for any workshop or job site.</p><h3>Why Choose Brass Fittings?</h3><ul style="list-style:disc"><li><strong>Corrosion resistance:</strong> Brass naturally resists rust and oxidation, ensuring a long service life even in wet or chemically challenging environments.</li><li><strong>Precision machining:</strong> CNC-machined components deliver consistent dimensions and thread quality for reliable, repeatable connections.</li><li><strong>Versatility:</strong> A single product line covers automotive, industrial, plumbing, pneumatic, and hydraulic applications.</li><li><strong>Broad compatibility:</strong> Fittings are available in standard NPT, BSP, and SAE thread forms to match virtually any existing system.</li></ul>

Product Details

The Brass Fittings 40040 is a 3/8 inch close red brass pipe nipple designed for non-potable water applications. This close nipple features minimal threading distance between connections, making it ideal for tight-fitting plumbing applications where space is limited.

Key Features:

  • Red brass construction for corrosion resistance and durability
  • 3/8 inch NPT (National Pipe Thread) connections on both ends
  • Close nipple design with threads running nearly the full length
  • Suitable for air, gas, oil, and non-potable water systems
  • Not approved for potable water use

Red brass pipe nipples are commonly used in industrial piping, compressed air systems, fuel lines, and general plumbing applications. The close nipple configuration allows two fittings to be joined with minimal gap, making it perfect for manifold assemblies and compact installations.

Important: This fitting is NOT to be used in potable water systems. For drinking water applications, select lead-free certified brass fittings.
