Nu-calgon NUCAL-4050-08 Leak Sealant Direct Inject 2-10 Tons

Product Description

The NU-CALGON NUCAL-4050-08 EasySeal Ultimate LS is a direct-inject refrigerant leak sealant designed for use in air conditioning and refrigeration systems ranging from 2 to 10 tons. Delivered via an injector tool, it introduces a chemical sealant directly into the refrigerant circuit, where it reacts with moisture at the leak site to form a durable seal. HVAC technicians use this product as a field repair solution for small refrigerant leaks without requiring a full system recovery and component replacement. One application treats systems across the full 2-to-10-ton range.

NUCAL-4050-08 is suited for residential and light commercial split systems, package units, and refrigeration equipment within the rated tonnage range. It is applied during a service call using the included injector tool, making it a practical option for technicians looking to address active refrigerant leaks in the field. It is intended for use in systems where the leak source has been identified and where a chemical sealant is an acceptable repair method per the service protocol in use.
