3/4 inch Copper Drop Ear 90 Degree Elbow Copper x Female

3/4 inch Press x Female Copper Lug Elbow – 90° Lead-Free Fitting for Potable Systems

The 3/4 inch Copper Lug 90° Elbow (Press x Female) is a lead-free copper fitting designed to change direction in copper tube systems where one end terminates in a female-threaded connection and the other uses a press-fit joint. It is suitable for use in potable water, hydronic heating, and low-pressure system layouts that require a compact, code-compliant directional change.

Manufactured from lead-free copper alloy, this fitting is engineered for compatibility with ASTM B88 tubing and is compliant with NSF/ANSI 61 and 372 standards for drinking water systems. The press connection supports flame-free installation, making it ideal for use in confined or finished environments where open flame is restricted.

Fitting Advantages for Field Applications

• ✅ Press x Female NPT Configuration Allows quick integration between press copper and threaded system components.
• ✅ Lead-Free Copper Alloy Certified for potable water use in all jurisdictions with low-lead requirements.
• ✅ Lug Support Facilitates secure bracketing or mounting during installation in wall cavities or equipment racks.
• ✅ 90° Sweep Provides efficient directional change without compromising flow characteristics.

Installation Guidance

Ensure tubing is properly reamed and marked for insertion depth prior to pressing. Use manufacturer-approved press tools and jaws specific to the fitting profile. For the female-threaded side, apply approved thread sealant and tighten to specification using a calibrated wrench. Support lugs may be anchored for mechanical stability during rough-in or final install.

Typical Use Cases

This fitting is commonly used in domestic water distribution systems, mechanical rooms, and commercial piping applications where hybrid press/thread transitions are required. Suitable for both retrofit and new construction, especially in fire-rated or no-flame zones.

Regulatory Compliance Insight

Lead-free fittings are mandated under the Safe Drinking Water Act for any system delivering potable water. This product meets all current low-lead content regulations and is approved for use in health-sensitive environments including schools and healthcare facilities.

The 3/4 inch Press x Female Copper Lug Elbow delivers reliable performance and installation flexibility for contractors working on code-compliant copper piping systems. With its hybrid connection design and certified lead-free construction, it’s a durable and efficient solution for modern plumbing applications.
