Mueller Streamline ELL00898 Wrot Copper 45 Degree Elbow

Product Description

The MUELLER STREAMLINE ELL00898 is a wrot copper 45-degree elbow fitting designed for sweat-solder copper tube connections in plumbing and HVAC piping systems. With a 1-inch by 1-inch C x C connection, it redirects flow at 45 degrees without the abrupt pressure drop associated with sharper fittings. Wrot copper construction delivers consistent wall thickness and a clean solder joint, making this fitting a standard choice for licensed plumbers and HVAC technicians working on residential and light commercial hydronic, domestic water, or refrigerant piping. The fitting weighs 0.16 pounds and measures 2.12 inches in height, 2.76 inches in length, and 1.21 inches in width.

This elbow is suited for new construction and retrofit applications where a 45-degree directional change is required in a copper sweat piping system. Typical install scenarios include domestic hot and cold water distribution, hydronic heating supply and return lines, and copper drain or vent branch offsets. It is appropriate for use anywhere wrot copper fittings are specified by code or design, including residential, multifamily, and light commercial projects.

Key Features

• Wrot copper construction provides consistent wall thickness and reliable solder joint integrity
• 45-degree angle offers a gradual directional change that reduces turbulence and pressure loss
• 1-inch C x C ends accept standard copper tube for sweat soldering
• Compact profile at 2.76 inches in length suits tight installation spaces
• Lightweight at 0.16 pounds, simplifying handling and inventory on the job site

Compatibility

Designed as an OEM-style replacement and standard-spec fitting for 1-inch nominal wrot copper sweat-solder piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and ASTM B88 copper tube standards. Shut off and drain the affected piping section before cutting and fitting. Clean tube ends and fitting cups thoroughly with emery cloth and flux before applying heat with a propane or MAP torch. Allow the joint to cool completely before restoring system pressure.
