Copper elbow 45° SANHA 15 mm model 5040 (MPN 1504015)

The SANHA copper 45° elbow model 5040 for 15 mm tubing is a solderable plumbing fitting designed to change the direction of copper pipe runs by 45 degrees. Constructed from corrosion-resistant copper, this elbow provides a compact and reliable turn for potable water, central heating and refrigeration piping systems where a gradual angle is preferred over a sharp 90° bend. The fitting accepts standard 15 mm copper tube and is intended for permanent, soldered joints in domestic and light commercial installations.

Advantages

This copper elbow offers material compatibility with copper tubing, ensuring consistent thermal and corrosion performance across the run. Its 45° angle reduces flow resistance and stress compared with sharper bends, while the solderable design creates leak-resistant permanent joints when properly installed. The compact form makes it suitable for installations with limited space and allows for neat, accurate alignment of pipework in heating and plumbing systems.

Suitable for

• Potable cold and hot water supply lines
• Central heating pipe networks
• Refrigeration and cooling circuits using copper tubing
• Tight spaces where a gradual directional change is required

Key specifications

• Material: copper (solderable)
• Angle: 45°
• Connection size: 15 mm tubing
• Application: plumbing, heating and refrigeration systems
• Suitable joint method: soldering (capillary joint)

How to use

Prepare the copper tubing by cutting squarely and deburring the inside and outside of the pipe ends. Clean the fitting and tube surfaces with an appropriate flux-cleaning brush or abrasive cloth to ensure a proper solder bond. Apply suitable flux to the joint, assemble the elbow onto the prepared tube to the correct seating depth, and heat evenly with a propane or MAPP gas torch until the flux changes and solder flows into the capillary gap. Allow the joint to cool naturally and remove excess flux residues. Confirm the joint is sound before restoring system pressure and performing leak tests in accordance with local codes.

Usage recommendations

Ensure the selected solder and flux are compatible with potable water systems if the elbow is used on drinking water lines; verify system operating temperatures and pressures are within the copper material limits. For installations subject to vibration or movement consider proper support and expansion allowances to reduce stress on soldered joints.
