Nitrogen Pressure Test Kit Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12783
Jlab Export is a leading Nitrogen Pressure Test Kit Manufacturer,and suppliers in India
This kit controls dry nitrogen for pressure testing a refrigeration or air conditioning circuit after brazing or a part change. Its regulator has a T-handle to set the outlet pressure and two guarded 63 mm gauges, one reading to 4400 psig and one to 1000 psig. The yellow charging hose, two adapters and the gaskets pack into a blow-moulded case.

Pressure Testing Practicals in the RAC Lab
A standing pressure test is the usual first exercise. Trainees fit the regulator to one of the Nitrogen Gas Cylinders. The yellow hose then runs to the centre port of the Manifold Gauges For Refrigeration Systems. They turn the T-handle in slowly to the test pressure on the unit nameplate, open the manifold to both sides of the circuit, then close it. A reading that falls during the hold time shows a leak.
To find it, they spray Bubble Solution For Leak Detection on each brazed joint and flare nut and look for growing bubbles. Once the repair holds pressure, the nitrogen is vented and the circuit goes on the Fast Vacuum Pumps before charging. Teachers use the two gauges to show the difference between cylinder pressure and the delivered test pressure.
Frequently Asked Questions
Why is nitrogen used for pressure testing instead of air?
Dry nitrogen is an inert gas and carries no moisture. Compressed air brings water vapour and oxygen into the circuit, and both harm the oil and the system once it runs. Refrigerant should never be vented just to look for a leak.
What do the two gauges on the regulator show?
The high pressure gauge, reading to 4400 psig (300 bar), shows the pressure left in the cylinder. The low pressure gauge, reading to 1000 psig (70 bar), shows the outlet pressure you set with the T-handle for the test.
What test pressure should I use?
Use the test pressure on the unit nameplate or in the equipment service data, and do not go above it. Raise the pressure in steps with the T-handle and watch the low pressure gauge as you go.
Which nitrogen cylinder does this kit fit?
The kit is made to work with the JLab nitrogen gas cylinders, which come with a trolley and safety caps. Fit the regulator to the cylinder valve, open the cylinder slowly and read the high pressure gauge before you set the outlet.
What is the R-410A straight adapter for?
It has a 1/4 in male flare on one end and a 5/16 in swivel female on the other. That lets the 1/4 in charging hose connect to the 5/16 in service ports found on R-410A equipment.
