Jlab Export is a leading Abrasive Strip (Sand Paper) Manufacturer,and suppliers in India
Copper tube and fittings must be bright and clean before brazing or soldering, and this fine abrasive strip is made for that job. It is a cloth-backed emery with brown corundum grain that tears by hand and is soft enough to wrap round a pipe. The strip is waterproof, oil resistant and resists clogging, and a pack holds 100 strips.

Pipe Joint Preparation Practicals
Brazing practice on Copper Pipe starts with a square cut from the Tube Cutter and a deburred end. Students then pull a strip round the tube end like a shoe-shine cloth, until the copper is bright for a little more than the depth of the socket. The inside of the fitting is cleaned with a Copper Fitting Brush.
Teachers can have each student braze two sample joints with the phosphor-copper Brazing Rod, one cleaned and one left dull. When the joints are cut open, the clean one shows filler drawn right through the gap, while the dull one has voids.
Frequently Asked Questions
Why does copper need cleaning before brazing?
Oxide, grease and dirt stop the filler from wetting the copper, so it balls up instead of flowing into the joint. A bright, clean surface lets the filler run round and through the gap by capillary action.
How do I keep grit out of the system?
Clean the tube with its open end pointing down, so dust falls away from the bore. Wipe off loose grit with a clean dry cloth before assembly, and never push the strip inside the tube end.
Can it be used wet?
Yes. The strip is waterproof, so it can be used with water for wet sanding, which keeps dust down and stops the grain from clogging. Dry the work well afterwards, especially before soldering or brazing.
How is emery cloth different from ordinary sand paper?
Emery cloth has a cloth backing, so it bends round a pipe and tears cleanly into strips without cracking. Paper-backed sheets suit flat work but split when wrapped tightly round a small tube.
What else can the strips be used on?
Besides copper, they polish and deburr steel and other metals, plastics, PVC, glass, porcelain, stone and painted surfaces. They also suit irregular shapes, where a rigid sanding block cannot follow the surface.
