The Xantus Products 10-101 System Defender is a direct inject AC leak sealant suitable for systems with capacities of one point five to five tons. This sealing solution is effective in protecting your HVAC system from leaks, moisture, friction, and operational noise right after installation.
This product works with all refrigerants except ammonia and does not require a system pump down for R-410A systems. It is compatible with standard injection equipment, such as a manifold, which makes application straightforward.
