Brass PEX Tubing Adapter Fittings

Brass PEX Tubing Adapter Fittings are designed to provide a reliable and secure transition between PEX tubing and various threaded or copper connection types. Manufactured from durable, corrosion-resistant brass, these adapters ensure long-lasting performance in both residential and commercial plumbing systems. Their precision-machined structure delivers a leak-free and stable connection, even in demanding temperature and pressure environments.

These fittings feature a simple yet robust installation process that supports both crimp and clamp ring systems, making them highly compatible with standard PEX plumbing methods. The smooth internal bore minimizes flow restriction, promoting efficient water delivery throughout the system. With their universal design, they are suitable for hot and cold water distribution lines, hydronic heating applications, and general plumbing installations.

Built to meet industry standards and code requirements, Brass PEX Tubing Adapter Fittings provide a dependable solution for contractors and homeowners seeking easy integration into existing systems. Their solid brass construction resists dezincification, ensuring long-term system integrity and reducing the need for future maintenance. Whether used for new construction or retrofit projects, these adapters offer performance, convenience, and peace of mind.

The adoption of PEX (Cross-linked Polyethylene) tubing has revolutionized modern residential and commercial plumbing due to its flexibility, cost-effectiveness, and corrosion resistance. LEGINES INDUSTRIAL MACHINERY INC. specializes in the high-precision manufacturing of Brass PEX Tubing Adapter Fittings, serving as the essential link between rigid brass valves/manifolds and flexible PEX lines. These adapters are crucial components in any PEX plumbing system, ensuring a watertight, high-integrity connection that meets stringent plumbing and building codes worldwide. Our adapters are designed for use with all common PEX connection methods, including Crimp (ASTM F1807), Cinch (ASTM F2098), and Compression methods, providing our clients with components that integrate seamlessly into their chosen installation system. The structural integrity and certified material composition of our brass adapters are paramount, as PEX systems are increasingly replacing traditional copper and galvanized steel in modern construction.

For PEX systems, which are overwhelmingly used for potable water distribution, Lead-Free compliance is not optional—it is mandatory across major international markets, including the United States (via the Safe Drinking Water Act) and Canada. Our Brass PEX Adapters are manufactured exclusively from certified Lead-Free alloys (such as Bismuth Brass C87850 or Silicon Brass C87700), ensuring full compliance with NSF/ANSI Standard 61 and 372. This commitment eliminates compliance risk for our distributors and contractors. Furthermore, the brass provides the necessary rigidity and thread strength that plastic PEX fittings cannot offer, particularly at the manifold connection point where high stress and repetitive threading are common. The external surface of the adapter features a precise barb or crimp profile, engineered to achieve the maximum specified pull-out resistance when the crimp ring or cinch clamp is applied. We employ specialized testing equipment to verify the strength of this mechanical bond, guaranteeing that the joint will not fail under hydrostatic pressure or temperature cycling.

Our product line of Brass PEX Tubing Adapter Fittings is comprehensive, supporting every need within a complex PEX system. We supply straight adapters for direct pipe-to-pipe connection, PEX to NPT or BSPP adapters for transitioning to threaded components, PEX to Copper Sweat adapters for renovation projects, and PEX manifold port adapters. We also manufacture the internal components for PEX ball valves and manifolds themselves. Our high-volume, automated production capabilities allow us to achieve extreme economies of scale, making us the preferred sourcing partner for large residential developers and major plumbing supply houses. By maintaining an unyielding focus on the dimensional accuracy of the barb profile and the certification of our Lead-Free materials, we ensure that LEGINES PEX fittings contribute directly to the reliable, long-term performance of modern plumbing infrastructure globally, solidifying our reputation as a trusted, compliance-focused components manufacturer.
