Mueller W03055 1-5/8 x 1-5/8 Copper CxC 45 Elbow

When you're running 1-5/8" line sets or heavy-duty potable water mains, the Mueller W03055 1-5/8 x 1-5/8 Copper CxC 45 Elbow is the industrial standard for making precise directional changes. This wrot copper 45-degree elbow is engineered for high-pressure HVACR and plumbing environments, featuring solder cup connections (Cup x Cup) that provide a tight, leak-proof fit for 1-5/8" OD tubing. Manufactured to ASME B16.22 and ASTM B75 standards, this fitting is UL recognized to 700 PSI, making it a reliable choice for high-pressure refrigerant lines in commercial systems. Unlike cast alternatives, this Mueller Streamline copper fitting is seamless and lead-free (NSF/ANSI 61G compliant), ensuring it handles everything from glycol loops to above-ground potable water supply without risk of contamination or premature fatigue. Its corrosion-resistant properties and 250°F temperature rating provide the thermal stability required for demanding mechanical rooms.

• Precision Tolerance: Wrot copper construction ensures consistent wall thickness and deep solder cups for maximum capillary action during brazing.
• High-Pressure Rated: Tested and recognized by UL to withstand operating pressures up to 700 PSI.
• Universal Compliance: Meets ASME B16.22, MSS SP-104, and NSF 61G for use in both refrigeration and potable water systems.
• Optimized Flow: The 45-degree angle reduces pressure drop compared to standard 90-degree elbows, improving overall system efficiency.

Is 1-5/8" an OD or nominal size?
For HVACR applications, 1-5/8" refers to the Outside Diameter (OD). In plumbing contexts, this is equivalent to 1-1/2" nominal size. Always verify your tubing measurements before soldering.

Can this fitting be used with silver solder?
Yes. This 1-5/8 inch copper elbow is compatible with standard 95/5 solder as well as high-temperature silver brazing alloys typically used in refrigeration.

Is this elbow suitable for VRF or VRV systems?
While technically rated for the pressure, some VRF manufacturers recommend long-radius bends to minimize turbulence. Check the specific equipment submittals before installation.
