American-Made Copper Fittings for Plumbing Excellence
Since 1940, Elkhart Products Corporation has been a cornerstone of precision manufacturing in the plumbing industry, delivering high-quality copper, brass, and wrot fittings that meet the evolving needs of our customers. Our journey began as a small screw machine product manufacturer, but through strategic expansion and innovation, we established a tube mill in Fayetteville, Arkansas, in 1962, enabling vertical integration that strengthens our control over material quality and production efficiency. Our commitment to American-made excellence is unwavering: from sourcing U.S.-mined copper to fabricating tube and manufacturing fittings domestically, we ensure every product reflects our dedication to craftsmanship and sustainability.Our in-house engineering team continuously drives advancements, resulting in technically superior offerings like our patented KLEENFIT technology and comprehensive solder and push-fit solutions. With dual facilities in Elkhart, Indiana, and Fayetteville, Arkansas, we maintain rigorous quality standards across all operations, including experimental labs for product development and compliance testing to meet lead-free regulations such as NSF 61-G and Vermont S152. Trust in our decades of expertise, transparent processes, and unwavering adherence to safety and environmental standards to deliver plumbing components that exceed expectations.

Services
Copper Fittings
Our copper fittings are engineered for durability and compliance in residential and commercial plumbing systems. Using U.S.-sourced materials, we produce solder and push-fit solutions meeting NSF 61-G standards. These components ensure leak-free connections and long-term performance in potable water systems. Rigorous in-house testing guarantees compatibility with modern piping requirements.
Wrot Copper
Wrot copper fittings provide corrosion-resistant connections for critical plumbing applications. Our manufacturing process achieves precise threading and dimensional accuracy, reducing field failures. Products comply with lead-free regulations while maintaining structural integrity under high pressure and temperature variations.
Lead-Free Compliance
We ensure all brass and bronze fittings meet 2014 federal and state lead-free mandates through material reformulation and third-party certifications like IAPMO File #N-4951. Our proprietary markings identify compliant products, and technical documentation supports code inspections in regulated markets.
