A/C Leak Freeze permanently seals air conditioner and refrigerant system leaks in home and commercial HVACR applications. A/C Leak Freeze is compatible with all standard refrigerant gases. It's polymer-free, tested to be non-clogging to the A/C compressor and recovery unit - it's a permanent fix. Leak Freeze Tech Tips. • Be sure to FULLY attach the reusable adapter to the low side ONLY. • Do not allow time to elapse once the system is running. Quickly, inject the product. • Recharge the system AFTER injecting AC LeakFreeze. • A caulk gun is helpful when pushing the product in the systems with high pressure on the low side. Insert entire syringe into sleeve of caulk gun and slowly ratchet down on top of the plunger. Always keep your free hand on top of syringe for stability. • AC LeakFreeze will not cause any damage to gauges. • When system pressure is high, particularly in R410a and R22 applications, we recommend putting the system in a shallow vacuum to alleviate low side pressure Features Permanently seals leaks in air conditioning and refrigeration systems Will continue to seal additional Leaks for up to 1 year that meet testing specifications Does not contain polymers Not activated by moisture or oxygen Tested to be non-clogging to a/c compressor and recovery unit Ideal for preventive maintenance and leak protection Can be mixed with refrigerant gas: R11, R12, R13, R14, R22, R23, R123, R124, R134a, R141b, R404a, R407c, R410a, R502, R503, R507, & R600 Seals Leaks Up To .05 mm 1/4 Fitting Size Permanently seals leaks in air conditioning and refrigeration systems Will continue to seal additional Leaks for up to 1 year that meet testing specification
