MULTIPURPOSE - The elbow copper fitting is good for use in HVAC, refrigeration systems, water supply systems, and water heating system etc. These applications need a secure and leak-free connection, which is essential. Its 90-degree angle design make it a convenient option for tight spaces. The fitting is suitable for use with copper pipes and tubes.WHAT YOU GET - The package comes withRELIABLE MATERIAL - The use of copper in these copper fittings provides benefits such as strong corrosion resistance, good thermal conductivity, and easy processing, If you want to use the elbow copper fitting, simply insert the tube into the C end and solder the C end to the pipeANGLE DESIGN - The elbow design allows the pipeline to maintain a right angle at the bend, reducing the degree of bending and resistance, and improving flow rate and efficiency. The long radius means that the bend in the pipe is more gradual, and the angle of the bend is smaller.KINDLY NOTE - Please confirm your copper pipe size when you choose.
