Mueller Industries W02728 Elbow

The Mueller Industries W02728 Elbow (Model WE-500L) is a high-performance 3/4" OD (5/8" ID) long radius 90-degree elbow engineered for precision in HVACR systems and potable water supply. Unlike standard short-turn fittings, the long radius design significantly reduces pressure drop and minimizes turbulence in refrigerant lines and pressurized plumbing, improving the overall efficiency of the system. Manufactured from high-grade wrot copper, this fitting features precise female solder cup connections that ensure a reliable, leak-free solder-joint when properly brazed or soldered by a professional.

Built to withstand demanding environments, the Mueller Streamline W02728 is NSF 61G certified and complies with ASME B16.22 standards. This ensures compatibility with copper piping in above-ground applications where corrosion resistance and structural integrity are non-negotiable. Whether you are performing a 90-degree copper elbow installation in a commercial chiller or a residential supply line, this fitting provides the consistency needed for high-pressure performance.

Key Benefits for Technicians:

• Reduced Flow Resistance: The long radius sweep optimizes fluid dynamics, lowering friction loss compared to standard 90s.
• Precision Machined: Consistent solder cup tolerances ensure easy fit-up and uniform capillary action during soldering.
• Wrot Copper Durability: Provides superior strength and thermal conductivity compared to cast alternatives.
• Broad Compliance: Meets ASME B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1 for industrial-grade reliability.
• Safe for Potable Water: Lead-free construction suitable for pressurized supply lines and domestic water systems.

Common Questions:

What is the difference between 3/4" OD and 5/8" ID?
In the HVACR trade, fittings are often measured by Outside Diameter (OD), which is 3/4". In plumbing, the Nominal Size or Inside Diameter (ID) is used, which is 5/8". This fitting serves both standards.

Can this fitting be used in high-pressure refrigeration?
Yes, the Mueller W02728 is designed for pressurized systems. Ensure proper brazing techniques are used to maintain the pressure rating of the copper fitting.

Why choose a long radius elbow over a short radius?
Long radius 90-degree elbows are preferred in systems where maintaining flow velocity and reducing turbulence is critical, such as suction lines in HVACR equipment.
