Direct from 3rd Party Supplier Add To Cart: NITROKITG is designed to assist the Technician in locating leaks in automotive air conditioning refrigerant system when it will NOT PASS A VACUUM TEST (large leak). In this test, an AC/R professional will remove all refrigerant from the unit, replace the gas with compressed nitrogen, and listen for any sounds. NITROGEN AIR CON PRESSURE LEAK TEST - MASTERCOOL. Unfortunately the desired product for your vehicle was not found. Some nitrogen leak detectors are designed to be set to test for a variety of different gases, allowing the devices to be more versatile. What nitrogen leak testers are you guys using and do sniffers work with them? CPS NITROKIT Automotive AC Nitrogen Leak Detector Kit. The bubble test method is a cheap form of leak testing and can assist in finding a variety of leaks, but it is not as reliable as other leak testing methods. You use dry nitrogen at 150 psi then you switch your gauges over to nitrogen decay test . NITROGEN AIR CON PRESSURE LEAK TEST - MASTERCOOL. This single-stage nitrogen regulator is used to test systems for leaks when they do not contain refrigerant. T-Handle for ease of pressure adjustment. This single-stage nitrogen regulator is used to test systems for leaks when they do not contain refrigerant. For leak tests, a filling adapter is required for the service connection as well as a tube adapter. With NITROKITG the Technician will be able to quickly and accurately locate large leaks in R1234yf and R134a air conditioning systems. Because nitrogen is held under greater pressure than the coolant, leaks create an audible hissing or whooshing sound as it exits the system. •Testing for leaks in pressure of HVAC & A/C systems. For this, all you have to do is enter your e-mail address. Worldwide shipping. Since air conditioning experts cannot be sure whether there is a leak or whether the refrigerant loss is the normal loss over time, careful leak detection is a must. 1/4” SAE flare outlet port, with control valve, to keep pressure on the regulator at all times T-Handle for ease […] You can, however, use other methods of leak detection as shown on this page. View now. This kit is needed to pre-check automotive A/C systems for leaks due to loose mechanical connections, leaks in hoses, evaporators and condensers, before re-introducing refrigerant back into the A/C system. Learn more about how an onsite nitrogen generator can help support your leak detection & testing efforts. Please note: Your subscription will only be complete after you have confirmed receipt of this e-mail. Yes, you are correct that the best way to check leaks is with 150 to 200 lbs dry nitrogen and wait at least an hour with no pressure drop. Alternatively you can use the drop-down menu to select other relevant spare parts in the respective category. An air conditioning technician replaces remaining refrigerant with compressed nitrogen, which allows you to actually hear any existing leaks. In the clamp-shell test, the test object is pressurized with the hydrogen-nitrogen mixture and a test point on the object is enclosed in a clamp shell from which the probe draws an air sample. After the end of the leak detection, the forming gas can be released into the ambient air. NITROKIT includes: a high quality 1-valve manifold with a 0-200 PSIG 3-1/8” gauge, 6’ (180cm) premium red ¼” service hose, 15’ yellow hose assembly with ¼” MPT x ¼” coupler and a high side automotive snap coupler. Designed for detecting and locating leaks in automotive air conditioning systems using pressurised Nitrogen gas. The SOUND created as the nitrogen exits the system will assist the Technician in locating the leak. Most kits require the insertion of dye into the low side air conditioning fitting. Yes, you are correct that the best way to check leaks is with 150 to 200 lbs dry nitrogen and wait at least an hour with no pressure drop. Detecting a leak in the air-conditioning system using forming gas. Add oil, close up the system, evacuate, see if vacuum holds, charge with nitrogen to 150 PSI MAXIMUM, see if nitrogen pressure holds. Leak detection through differential pressure is mainly suitable for the initial testing of strongly leaking or even empty systems. This single stage nitrogen regulator is used to test systems for leaks when they do not contain refrigerant. For those of you worried about using compressed air because of moisture. Please try again or use the manual vehicle search. Here you will find useful information and handy tips relating to leak detection in automotive air-conditioning systems. The leak can be detected through a "hissing" noise. Nitrogen gas is used to detect leaks in a variety of plumbing or piping applications.
