Lennox 58J97 Flare Kit

The Lennox 58J97 Flare Kit (also cataloged as 58J9701) is a critical TXV Flare Adapter Kit engineered for high-pressure refrigerant line connections in residential and light commercial HVAC systems. This genuine OEM Lennox part, also identified by model number LB-86210A, provides the necessary components to transition from standard flare fittings to thermostatic expansion valve (TXV) ports without requiring manual brazing or specialized field fabrication. Each kit features precision-machined brass flare adapters in both 3/8-inch and 1/2-inch sizes, ensuring broad compatibility across various liquid and suction line configurations. The inclusion of a high-grade teflon washer and double retaining seal allows technicians to maintain a leak-free seal under demanding thermal cycles. Using this factory-spec HVAC flare adapter ensures the integrity of the refrigeration circuit while simplifying the installation of replacement expansion valves in tight air handler or evaporator coil cabinets where open flames are restricted.

Key Benefits:

• Universal Selection: Includes both 3/8" and 1/2" flare adapters to fit standard split system line sets.
• Direct Replacement: Fully interchangeable with Lennox 58J9701 and replaces LB-86210A for seamless service.
• Corrosion Resistant: Heavy-duty brass construction withstands moisture and environmental exposure to prevent fitting degradation.
• Leak Prevention: Precision-threaded connections and specialized seals ensure a reliable refrigerant-tight connection.
• Time-Saving: Eliminates the need for swaging or brazing, reducing the risk of internal oxidation and debris in the system.
