Nitrogen Gas Cylinders Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12782
Jlab Export is a leading Nitrogen Gas Cylinders Manufacturer,and suppliers in India
For a workshop or training lab that brazes and pressure-tests pipework every day, this 50 litre nitrogen cylinder keeps a large supply of dry gas on hand. It stands on its own compatible trolley for moving between benches, and a safety cap guards the valve when no regulator is fitted.

Workshop Exercises with Nitrogen
One large cylinder can serve a whole class in turn. Groups braze copper joints with nitrogen flowing through the pipe, metered by the Nitrogen Flow Regulator Meter For Brazing, so no oxide scale forms inside. The same supply drives a standing pressure test on a split or window AC unit.
For that test, students pressurise the unit through a regulator and spray the joints with Bubble Solution For Leak Detection. They then watch the gauge for any drop over time. After a flush with the Flush Machine, nitrogen from the cylinder also pushes the last of the solvent out through the nitrogen connection on the machine.
Frequently Asked Questions
How long will a 50 litre cylinder last?
That depends on its fill pressure and the work. Purging uses a low flow for a few minutes per joint, while pressure tests on large systems take more gas. It lasts many times longer than a small portable cylinder.
Is a single-stage or two-stage regulator better with this cylinder?
A single-stage regulator suits most purging and testing, but its outlet setting drifts as the cylinder pressure falls. A two-stage regulator holds the setting steadier through a long test. Either way, fit a regulator every time and never run gas from the cylinder valve straight into pipework.
Why does the pressure change during a standing test?
Nitrogen pressure rises and falls with temperature. A circuit warming in the sun shows a slow rise, and one cooling in the evening shows a fall that can look like a leak. Note the temperature at the start and end of the test. Keep the test pressure below the rating of the weakest part.
Why is a trolley supplied?
A cylinder of this size is heavy and awkward to carry. The compatible trolley lets one person wheel it between benches and keeps it upright in use, with the cylinder chained or strapped in place.
Can the cylinder be refilled by a local gas supplier?
Nitrogen cylinders are normally refilled or exchanged by an industrial gas supplier. Check that the cylinder valve outlet suits the regulator you use, since outlet threads differ between regions. Keep the safety cap on the valve whenever the cylinder travels.
