The Lennox 65G58 TXV is a precision-engineered thermostatic expansion valve designed for residential and light commercial HVAC systems with a 1.5-ton cooling capacity. This OEM replacement part is critical for maintaining the correct superheat and ensuring the evaporator coil operates at peak efficiency. Featuring 3/8" x 5/8" ODF connections and a 30-inch capillary tube, the 65G58 is built for a direct fit and seamless integration into existing Lennox air conditioning and heat pump units. It is fully compatible with R-22, R-410A, and R-407C refrigerants, providing the versatility required for various field applications. As a veteran technician knows, the 65G58 is identical to the 65G5801, allowing for streamlined inventory management and reliable service calls. This valve regulates refrigerant flow based on evaporator temperature, preventing liquid slugging and protecting the compressor from premature wear during demanding cycles.

• Precise Refrigerant Control: Optimizes 1.5-ton system performance by maintaining accurate superheat levels across variable loads.
• Universal Refrigerant Compatibility: Designed for use with R-410A, R-22, and R-407C, making it a versatile tool for modern and legacy systems.
• Durable OEM Construction: Features high-quality materials and a 30-inch capillary for long-term vibration resistance and thermal response.
