The Goodman 20201802 Drain Hose Tube is a genuine OEM condensate hose for the Goodman GKS90453BXAB high-efficiency gas furnace and compatible GKS90 models. This molded tube carries acidic condensate between the collector box, drain trap, and outlet on 90%+ AFUE furnaces. Original hoses harden, crack, or collapse over years of exposure to hot, corrosive condensate — a failed hose causes leaks, water pooling, and pressure-switch trips that shut the furnace down.

Specifications

Part Type: Condensate drain hose / tube
OEM Part Number: 20201802
Application: Condensing (90%+ AFUE) furnaces
Fits: Goodman GKS90453BXAB and compatible GKS90 furnaces
Material: Molded, condensate-resistant tubing with factory bends
Brand: Goodman OEM

OEM vs. Generic

Generic bulk hose lacks the pre-molded bends and exact length of this part, so it kinks or pulls off the barbs and restricts drainage. The genuine Goodman 20201802 is shaped to route cleanly with no kinks and seals tight on the factory fittings — the reliable fix for condensate leaks.

Installation Difficulty

Rating: Easy. With the furnace powered off, pull the old hose from its barbs and press the new hose fully onto each fitting, matching the original routing. Verify no kinks and check for leaks on startup. A common DIY-friendly part, though a technician can confirm the drain system.
