Goodman 10254303 Rubber Coupling

The Goodman 10254303 is a genuine OEM rubber coupling built as a direct-fit replacement for the Goodman AKSS921155DXAA gas furnace and compatible models. This flexible seal joins tubing and drain/condensate connections, providing a leak-tight, vibration-absorbing junction between components. Over time, rubber couplings can harden, crack, or lose their seal, leading to condensate leaks or pressure-sensing errors. Replacing a degraded coupling with the factory part restores a clean, reliable seal.

Specifications

OEM Part Number: 10254303
Brand: Goodman
Component Type: Rubber coupling / gasket seal
Equipment: Gas Furnace
Fits: AKSS921155DXAA and compatible models
Material: Flexible EPDM-style rubber

OEM vs. Generic

The genuine Goodman coupling matches the exact inner diameter and wall thickness required for a secure fit on factory tubing. Generic couplings that are slightly off-size can slip, leak, or fail to seat on the pressure/condensate lines. The OEM part ensures a proper, lasting seal without guesswork.

Installation Difficulty

Easy. This is a simple slip-on component, typically secured with clamps and requiring only basic hand tools. Confirm the connection is fully seated and clamped to prevent leaks. Always shut off gas and power before servicing the furnace.
