The RECTORSEAL 45309 is a refrigerant leak sealant formulated for mini split systems. It is injected into the refrigerant circuit to locate and seal small leaks without requiring a full system recovery or teardown. The product is designed for use by licensed HVAC technicians servicing ductless mini split equipment. It works within the refrigerant stream to form a seal at leak points, allowing the system to return to normal operation after treatment.
The 45309 is intended for residential and light commercial ductless mini split systems where small refrigerant leaks have developed in the evaporator, condenser, or interconnecting lines. It is suited for service calls where a traditional brazed repair is not practical or accessible. HVAC technicians use this product as part of a leak mitigation procedure when system downtime must be minimized.
Designed as an OEM-compatible refrigerant leak sealant for ductless mini split systems. No specific model or system family compatibility data was provided in the product input.
This product should be installed by a licensed HVAC technician in accordance with applicable refrigerant handling regulations, including EPA Section 608 requirements. Before injection, confirm the refrigerant type in the system is compatible with the sealant formulation. Follow the manufacturer instructions for injection procedure and dosage. Do not use in systems with severe leaks or physical damage to refrigerant lines.
