Refillable Universal Oil/Dye Injector Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-12768
Jlab Export is a leading Refillable Universal Oil/Dye Injector Manufacturer,and suppliers in India
This refillable injector puts a measured shot of compressor oil or UV leak-detection dye into a refrigeration or air-conditioning system that is already charged. It couples through an auto shut-off valve adapter with a 1/4 in connection. The valve closes when the injector comes off the service port, so little refrigerant or dye escapes.

Workshop Practice with the Injector
A common RAC workshop exercise is tracing a slow leak with dye. Trainees fill the injector from a bottle of Standard Universal Ultraviolet A/C Dyes, couple it to the low-side service port and inject the dye while the compressor runs. Once the dye has circulated with the oil, they scan each joint and valve with a Rechargeable High Intensity LED UV Flashlight and mark any spot that glows.
The same tool serves an oil top-up practical. Students first note the suction pressure on Manifold Gauges for Air Conditioning, then inject a measured charge of POE Oil into a system built for that oil. Teachers can use the exercise to show why the oil must match the type named for the compressor.
Frequently Asked Questions
How much dye should I inject?
Use the dose printed on the dye bottle, which is usually set by the size of the system charge. Too little dye makes small leaks hard to see. Too much only dilutes the compressor oil, so stop once the stated amount is in.
Can one injector handle both oil and dye?
Yes, it is a universal injector for either fluid. Empty and wipe it out when you change over, so dye is not carried into an oil charge and one oil type is not mixed with another.
Should the system be running during injection?
In most cases, yes. Connect to the low-pressure side with the compressor running, so the suction draws the charge in and carries it round with the oil. The high side runs at a much higher pressure and is not used for injection.
Will it fit the service ports on my system?
It has a 1/4 in auto shut-off valve connection, which suits standard 1/4 in flare service ports. Ports of another size, and the quick-connect ports on car AC systems, need a matching adapter or coupler first.
