Goodman 10254303 Rubber Coupling

The Goodman 10254303 rubber coupling is a genuine OEM sealing connector designed for the GMH950453BXAF 96% AFUE two-stage gas furnace and compatible Goodman/Amana models. This flexible coupling creates a leak-tight connection in the condensate drain and induced-draft assembly, preventing water leakage and maintaining proper pressure sealing during furnace operation.

Specifications

OEM Part Number: 10254303
Component Type: Rubber coupling / drain seal
Material: Molded EPDM-grade rubber
Fits: Goodman GMH950453BXAF furnace
Application: Condensate / draft connection

OEM vs. Generic

The OEM 10254303 is factory-molded to exact Goodman tolerances for a guaranteed leak-free seal and long service life. A generic equivalent offers a budget-friendly universal coupling that fits most standard connections but may require minor trimming or extra clamping. Both restore a proper seal; OEM is recommended for warranty-covered equipment.

Installation Difficulty

Easy (1/5) — Slip-on replacement. Power down the furnace, slide off the old coupling, seat the new one, and secure any clamps. Typical time: under 10 minutes with basic hand tools.

Fits Goodman GMH950453BXAF. Verify your part number before ordering.
