  • WORKS WITH YOUR SYSTEM - R410a, R22, R32, R454B, R134a, R290, R600a. Compatible with every refrigerant in residential and light commercial use. Central AC, heat pumps, ductless mini-splits, window units. Not for ammonia (R717) or CO2 (R744). Check your unit's service panel - if the refrigerant is listed here, you're covered.
  • NO PUMP-DOWN, 45 MINUTES - connect to low-side port, install using refrigerant or high side pressure, disconnect. Works on a fully charged, running system. No vacuum pump. No manifold gauge required (though you can use one). The inject hose threads to your low-side service port in seconds. Squeeze the trigger. Let the system run 45 minutes. Done.
  • SAFE FOR TXVs, EXPANSION VALVES, AND YOUR SYSTEM WARRANTY - ProSeal XL4 does not clog thermal expansion valves, TEVs, capillary tubes, or Schrader valves. Safe for all manifold gauges, recovery equipment, and hoses. In 3 million+ installations since 2014, ProSeal has never voided a system warranty.
  • SEALS PINHOLE LEAKS IN CONDENSERS, EVAPORATORS, LINE SETS, O-RINGS AND SOLDER JOINTS - For leaks where the system does not lose its full charge in under 7 days. If your system goes empty in less than 7 days, the leak is too large for a sealant. The formula travels with the refrigerant (not the oil), reaching vapor-phase leak sites that oil-carried sealants miss.
  • INVENTED HERE IN 2014 - 3 MILLION UNITS SOLD - THE FORMULA BEHIND THE MARKET - Enviro-Safe designed the Direct Inject system in 2014. Every competing brand started reselling after 2015. This is the original product - same formula, same family-owned factory in Pekin, Illinois, operating since 1996. Computer-blended to pharmaceutical standards. Made in the USA.
