Lennox 28J96 Gasket 326058-757 High Flow Orifice: The 5/8"

High Flow Orifice: The 5/8" port design minimizes pressure drop across the valve

You can temporarily restore function using a fine abrasive like steel wool

Using a Goodman replacement expansion valve restores the proper pressure drop needed for cooling

these units are commonly factory-preset to 395 PSI for standard commercial high-pressure protection

but the technical specs and mounting footprint remain compatible for replacement

Lennox 28J96 Gasket 326058-757 High Flow Orifice: The 5/8"The Lennox 28J96 Gasket, also identified by part number LB 69815, is a critical OEM inducer motor gasket designed to establish a high integrity seal between the combustion air inducer and the orifice plate. Measuring approximately 8. 66 inches x 5. 71 inches with a 0. 125 inch thickness, this specialized component is vital for maintaining the static pressure required for safe furnace operation. A compromised gasket leads to air bypass, reduced venting
