Elbow Fitting Manufacturer,Supplier and Exporter in India
Product Code : EL-MWLE-13037
Jlab Export is a leading Elbow Fitting Manufacturer,and suppliers in India
A copper elbow turns a refrigeration line round a corner where the tube cannot be bent, such as a tight space beside a compressor or coil. This elbow is made in 6, 8, 10, 12 and 14 mm sizes, each matching copper tube of the same outside diameter. Copper fittings of this kind are joined to the tube by brazing.

Brazing Practicals with Copper Elbows
Students cut copper tube square with a Tube Cutter and take off the inner burr with Deburring Tools. A Copper Fitting Brush cleans the tube end and the inside of the elbow. Each joint is then heated with the Gas Welding Plant and filled with a copper-phosphorus Brazing Rod.
While brazing, a slow flow of nitrogen from a Nitrogen Flow Regulator Meter For Brazing keeps oxide scale from forming inside the line. A good exercise is to route one line round a corner twice: once with elbows and once with a bend made on a Copper Pipe Bender. Students then count the joints in each run and check both with bubble solution after a pressure test.
Frequently Asked Questions
Which size elbow do I need?
Match the elbow to the outside diameter of the copper tube, so 8 mm tube takes the 8 mm elbow. Measure the tube with a caliper if the size is not marked on the coil.
Should I use an elbow or bend the tube?
Bend the tube where you can, because a smooth bend has no joint that can leak. Use an elbow where the space is too tight for a bender or where the line must turn sharply.
Do copper elbows need flux for brazing?
Not for copper-to-copper joints made with a copper-phosphorus rod, since the phosphorus cleans the copper as it melts. Brass parts need a flux as well. Steel is never brazed with a copper-phosphorus rod, because the phosphorus makes brittle joints on steel.
Why purge nitrogen while brazing?
Hot copper reacts with air and forms black oxide scale inside the tube. A slow nitrogen flow keeps air out, so no flakes break off later to block a capillary tube or filter drier.
