HVAC systems and automotive A/C systems Leak Sealer Kit 30ML ST-508

The HVAC/R Leak Sealer Kit 30ML is a complete professional toolkit designed to repair and permanently seal micro leaks in air conditioning and refrigeration systems.

Formulated for use with a wide range of refrigerants - including R22, R134a, R404A, R507A, and R410A - this kit provides a fast, safe, and reliable solution to maintain system performance and extend equipment lifespan.

How It Works

1. Injection into the System
   The kit includes a 30ml syringe of leak sealer, injected through the low-pressure port or quick couplers.
   The sealer mixes with the refrigerant and lubricant, circulating throughout the entire system.
2. Leak Sealing Process
   During system operation, the sealer reacts at leak points to form a durable polymer seal, closing micro cracks or holes up to 0.3mm in diameter.
   Compatible with compressors, condensers, evaporators, pipes, and fittings.
3. Easy, On-Site Operation
   Equipped with multiple adapters (1/4" SAE, 5/16" SAE, and Lock Adapter).
   Includes a cartridge insertion tool and a flexible low-pressure hose for convenient injection.
   All components are stored in a durable plastic case for portability and quick access.
