As a seasoned technician, you know that managing condensate in high-efficiency equipment is non-negotiable for system longevity. The Nordyne 663714R Drain Assembly is a factory-authorized OEM replacement part designed for precision fluid management in Nordyne and Coleman air handlers and condensing furnaces. This 15-inch HVAC condensate drain assembly features a robust 2-inch PVC slip inlet and a 1/2-inch OD barbed outlet, ensuring a secure, leak-free transition for gravity-fed drainage. Engineered to prevent air infiltration and maintain the primary trap seal, the Nordyne 663714R is the direct spec for resolving issues with cracked or clogged factory drains. Whether you are performing a seasonal PM or an emergency repair, utilizing this genuine in-line drain assembly ensures the condensing furnace drainage meets original manufacturer specs, protecting the heat exchanger and secondary drain pan from potential moisture overflow or corrosion. This assembly is cross-compatible with legacy part numbers 371890 and 663588, providing a streamlined HVAC part compatibility solution for your service truck.

• OEM Precision: Direct 15" x 2" in-line drain assembly ensures perfect fitment and eliminates the need for field-fabricated pipe work.
• Durable Construction: Manufactured from corrosion-resistant PVC to withstand the acidic condensate typical of high-efficiency gas furnaces.
• Optimized Flow: Features a high-quality barbed fitting for 1/2" ID tubing, providing a tight seal to prevent secondary leaks.
• Versatile Application: Validated for use across multiple Nordyne brands, including Miller, Intertherm, and Coleman residential units.

Is the Nordyne 663714R compatible with all high-efficiency furnaces?
While this is a common Nordyne furnace drain line, you must verify the specific model and serial number. It is specifically engineered for units requiring a 2-inch PVC slip-fit connection.

Does this assembly include the drainage hose or clamps?
This is the main Nordyne 663714R assembly body. We recommend having 1/2" OD tubing and stainless steel clamps ready for a professional, secure installation.

Why is my furnace leaking from the internal drain assembly?
Leaks often occur due to stress cracks on the barbed nipple or sediment buildup clogging the trap. A direct replacement with a genuine OEM drain assembly is the standard protocol to restore proper moisture removal.
