Goodman B2832503 Flue Collector Gasket (24.5")

The Goodman B2832503 is a genuine OEM 24.5-inch flue collector box gasket engineered for the GMPN120-5 gas furnace. This high-temperature gasket seals the flue collector box to the heat exchanger, ensuring combustion gases are captured and routed to the vent without leaking into the cabinet. A degraded or crushed gasket is a common source of flue-gas leakage and pressure-switch faults — replacing it with the factory part restores a proven, code-compliant seal.

Specifications

OEM Part Number: B2832503
Length: 24.5 inches
Type: Flue collector box gasket
Compatibility: Goodman GMPN120-5 gas furnace
Rating: High-temperature combustion seal
Function: Seals collector box to heat exchanger

OEM vs. Generic

OEM guarantees the correct 24.5-inch length, profile, and heat rating for a sealed combustion path. Generic gasket stock rarely matches the collector-box contour and may compress unevenly, leaving leak points. For a flue-gas sealing surface, OEM is the safe choice.

Installation Difficulty

Moderate (3/5). Requires removing the flue collector box, cleaning the mating surface, seating the new gasket, and re-torquing the fasteners evenly. A combustion/leak check is recommended afterward. Best for an experienced DIYer or HVAC technician.
