Supercool STOPA A/C Leak Stop Seals, 4oz

SKU CH-PPF0-BVJBJ

Stops small A/C leaks in evaporators, condensers, hoses, gaskets and seals while adding UV dye for detection

  • Stops small A/C leaks in evaporators, condensers, hoses, gaskets and seals
  • UV dye pinpoints leak location for faster repairs
  • Compatible with PAG, ester and mineral oils for broad system use
  • High 570 °F boiling point resists breakdown under pressure
  • 4 oz aerosol can treats one standard R-134a system

What it does

Supercool STOPA A/C Leak Stop Seals is a leak detection dye formulated for automotive air-conditioning systems using R-134a refrigerant. It targets small leaks in evaporators, condensers, hoses, gaskets and seals. The product suits technicians and vehicle owners who need a single-step sealant and dye combination.

Heat and pressure limits

The liquid has a boiling point of 570 degrees F and a flash point of 425 degrees F, so it remains stable under normal A/C operating temperatures and pressures. Specific gravity ranges from 0.85 to 0.097. These figures indicate the fluid will not vaporise prematurely or create a fire hazard during typical service work.

Compatibility and contents

The formula works with PAG, ester and mineral oils, covering the common lubricants found in R-134a systems. The 4 oz aerosol can delivers both sealant and UV dye in one charge, eliminating the need for separate injection tools or additional dye bottles. No other accessories or software are included.

Questions about this item

How is the 4 oz can of Supercool STOPA A/C Leak Stop installed and what step do people often miss?

Shake the can well, attach the charging hose to the low-side service port with the engine running and A/C on maximum, then dispense the contents; the step often missed is inverting the can to ensure the liquid sealant enters the system rather than just propellant gas.

What maintenance or replacement will the Supercool STOPA A/C Leak Stop require after it seals a leak?

The product is a one-time treatment; once it circulates and seals small leaks in evaporators, condensers, hoses, gaskets or seals, no further maintenance of the additive itself is needed, though the refrigerant charge should be checked for correct pressure.

What is the first limit that appears when the sealed system runs under sustained high-temperature conditions?

The sealant's flash point is 425 degrees F and its boiling point is 570 degrees F; sustained temperatures approaching the flash point would be the first safety limit encountered.
