Find the leak first, then seal it: a visible trace with UV dye, a quick scan with an electronic detector, a precise pressure test with a hydrogen-nitrogen mix. Cracks up to 300 microns are sealed permanently with Seal Pro.
Method
Charging a system before the leak is found is throwing money away. Three methods for three different situations:
UV fluid is added to the system and the vehicle is run; the leak point shows up as a glowing trace under a UV torch. The most reliable method for slow leaks.
Connection points are scanned with the probe; the leak is found with an audible alarm at 3 g/yr sensitivity. For a quick first scan.
The empty system is pressurised with forming gas and the pressure drop is monitored. For the smallest leaks and verification after repair.
Products
Listed with catalogue codes; all available from elcimarketim.com or our dealers.
Comprehensive UV service kit for professional A/C leak detection; in a carrying case.
Highly fluorescent universal UV leak detection fluid; the leak point is easy to see under UV light.
Large-pack UV leak detection fluid for professional, high-volume workshop use.
Permanently seals the leak in the A/C system while circulating; the definitive fix for slow leaks that take three weeks or longer.
Portable detector that scans connection points with its probe and signals the leak with an audible alarm.
Leak tester
Pressurises the A/C system with forming gas (95% nitrogen / 5% hydrogen) and reveals even the smallest leak by monitoring the pressure drop. For post-repair verification on passenger cars, electric and hybrid vehicles, commercial and industrial A/C systems.
Guide
The right tool depends on the size of the leak and the state of the system.
| Method | When | What you need | Conclusion |
|---|---|---|---|
| UV dye | Slow leaks; check after the vehicle has been driven for a few days | UV fluid, injector, UV torch | The leak point shows as a glowing trace |
| Electronic detector | Quick first scan, connection points | Startek detector | Audible alarm; 3 g/yr sensitivity |
| Hydrogen-nitrogen test | With the system empty; post-repair verification | Hydro Trace PRO ATC, forming gas cylinder | Pressure drop report |
| Seal Pro sealer | Cracks under 300 microns; hoses, O‑rings, metal | Seal Pro1 or HVACR Seal Pro | The leak is sealed permanently while circulating |
For large leaks (a torn hose, a punctured condenser) a sealer is not the answer; the part must be replaced. After the repair the system is evacuated, tightness is verified with a vacuum test and refrigerant is charged to the manufacturer's value.
Frequently Asked Questions
The Primalec formula stays in circulation and hardens only at the leak point; it is compatible with R134a and R1234yf. If there is no leak, its drying effect improves cooling performance. For large leaks the part must be replaced rather than sealed.
100 ml of ELCİ UV Leak covers about 13 vehicles, 500 ml about 65. The 2 × 100 ml in the Micron Leak kit covers 26 vehicles.
The compact 21 LED / 395 nm torch (ELC‑S09) is enough for most workshops; the 365 nm / 12 W rechargeable torch (ELC‑S12) is more powerful for heavy use and traces that are hard to see in daylight.
No. The DKT 203 smoke test is for air and fuel-vapour systems. For refrigerant leaks in the A/C circuit, use UV dye, an electronic detector or the hydrogen-nitrogen test.
