Mueller W02055 1-3/8" OD Elbow

The Mueller Streamline W02055 is a professional-grade 1-3/8" OD copper 90-degree elbow precision-engineered for critical flow redirection in HVACR systems and commercial plumbing. This wrot copper fitting features a long radius (LR) design, which significantly reduces internal turbulence and pressure drop compared to standard short-radius elbows, making it ideal for maintaining high system efficiency in refrigerant discharge or suction lines. Designed for CxC (Cup x Cup) solder connections, this 1-1/4" nominal size elbow ensures a reliable, leak-proof joint when brazed according to industry standards.

Manufactured from high-purity UNS C12200 copper, the W02055 is corrosion-resistant and built to withstand the rigorous demands of aboveground water-supply systems and pressurized refrigerant circuits. It meets multiple technical certifications, including ASME B16.22 for wrot copper pressure fittings and NSF/ANSI 61 for potable water safety. With a 700 PSI pressure rating at 250°F, this solder joint fitting provides the structural integrity required for modern R-410A refrigeration systems and heavy-duty mechanical piping installations.

• Long Radius Design: Optimizes fluid dynamics and minimizes pressure drop across 90-degree turns.
• High Pressure Performance: Rated for up to 700 PSI, making it fully compatible with high-pressure refrigerants like R-410A.
• Industrial Durability: Constructed from wrot copper for superior strength, thermal conductivity, and corrosion resistance.
• Standard Compliance: Meets ASME B16.22 and NSF 61G requirements for mechanical and potable water applications.
• Easy Installation: Precision-machined solder cups provide a consistent fit for fast, secure brazing or soldering.

• What is the difference between 1-3/8" OD and 1-1/4" Nominal? In the HVACR industry, fittings are measured by Outside Diameter (OD), whereas plumbing uses Nominal (ID) sizing. This 1-3/8" OD elbow is the exact same size as a 1-1/4" nominal plumbing fitting.
• Is this elbow suitable for brazing in refrigeration lines? Yes, its wrot copper construction is specifically designed for brazing in ACR applications and is compatible with standard silver-bearing alloys.
• Why choose a Long Radius (LR) elbow over a Short Radius (SR)? Long radius elbows allow for a smoother transition, reducing the equivalent length of pipe and improving the overall coefficient of performance (COP) of the system.
