- WORKS WITH R410a, R22, R32, R454B, R134a AND MORE - all residential and light commercial refrigerants. Same ProSeal XL4 formula as our standard product. Added UV dye circulates simultaneously - no separate step. Compatible with all oils. Not for ammonia or CO2. If it's in a residential or commercial HVAC system, it's covered.
- SEAL THE LEAK AND FIND IT IN THE SAME INJECT - two jobs, one cartridge. ProSeal seals the pinhole. The UV dye marks every point the refrigerant traveled - leak site glows under any UV light. If the seal holds, you know where it was. If the system needs further service, your tech sees exactly where to work.
- NO PUMP-DOWN - 45 minutes on a running system. Connect to the low-side port install using refrigerant or high side pressure. Disconnect. Let the system run 45 minutes. The sealant and dye inject together in one trigger pull. No second application. No additional equipment.
- SAFE FOR TXVs, EXPANSION VALVES, AND ALL SYSTEM COMPONENTS - has never voided a warranty. The UV dye is the same grade factory-installed by automakers. Safe for manifold gauges, TXVs, TEVs, capillary tubes, Schrader valves, and recovery equipment. In 3 million+ installations, ProSeal has never voided a system warranty.
- ORIGINAL MANUFACTURER SINCE 2014 - every competitor resells our formula, we make it. Enviro-Safe invented Direct Inject. Every other brand started after 2015 sourcing the same formula. This is the source - family-owned in Pekin, Illinois since 1996. Computer-blended to pharmaceutical standards. Made in the USA.
