The Goodman 10254303 is a genuine OEM rubber coupling and gasket seal for AMH950904CXAA gas furnaces. This flexible coupling joins condensate drain or trap connections, forming a watertight seal that keeps acidic condensate contained and prevents drips onto the furnace base, burner, or nearby components. Over time rubber couplings harden and crack, leading to slow leaks and water damage — a simple, inexpensive part that protects far more expensive components.

Specifications

Type: Rubber coupling / gasket seal
Function: Leak-free condensate/drain connection
Material: Condensate-rated flexible rubber
Fits: Goodman/Amana AMH950904CXAA and compatible furnaces
OEM Part Number: 10254303

OEM vs. Generic

Rubber couplings must match the exact inside diameter and wall thickness to seal on the original fittings. Universal couplings often gap or bulge under clamp pressure, reintroducing leaks. This OEM coupling is molded to factory dimensions for a tight, reliable seal every time.

Install Difficulty: Easy

Rated Easy (~10 minutes). Power down the furnace, loosen or slide off the old coupling, clean the fitting surfaces, and press the new coupling into place, securing any clamps. Confirm no leaks after restoring condensate flow.
