Nu-Calgon EasySeal Direct Inject 4050-08 – Quick, One-Time Sealant for 2–10 Ton HVAC Systems

Overview

Nu-Calgon EasySeal Direct Inject marks a new generation of sealants designed for straightforward installation. Its patent pending injection method makes sealing easier and less labor-intensive than traditional sealants. With this injection system, pumping down the unit is a thing of the past, which can speed up maintenance tasks and reduce downtime in the field.

Designed for 2 to 10 ton systems, this formula works with all refrigerants and oils, providing a concentrated solution that minimizes the amount of material inside the system. A clear tube lets technicians visually confirm the sealant entering the lines, offering immediate feedback as you work and helping you monitor progress in real time.
