Dorman Metal Heater Hose Connector 90° 3/4 x 3/4 OE FIX — Machined Metal, Pressure-Tested

The Dorman 800-418HP is a 90° metal heater hose connector that replaces brittle plastic OE pieces to deliver a longer-lasting, leak-resistant HVAC hose connection.

Many factory heater hose connectors are molded from plastic that becomes fragile after years of heat and abrasion, leading to coolant leaks or detached hoses. The Dorman 800-418HP OE FIX replacement upgrades that vulnerable connection with a machined metal connector built to meet the same fitment as the original while offering improved durability and pressure resistance. It’s engineered for a straightforward swap on compatible vehicles and is pressure-tested to help restore reliable heater hose performance.

Will this metal connector fit my vehicle?

The Dorman 800-418HP is manufactured to match factory dimensions for a seamless fit on specified models. Before ordering, use the vehicle selection (garage) tool and check the Confirmed Fit indicator to make sure your trim and year are covered.

• Compatible with many GM, Ford, Chrysler, Dodge, Jeep, Lincoln and Saab models—check years listed.
• 3/4" x 3/4" hose size with a 90° bend for common heater hose routings.
• If an “i” appears in the Confirmed Fit bar, hover for fit notes that may affect compatibility.

How does this metal connector improve on the original plastic part?

Unlike plastic fittings that can crack from repeated thermal cycling and abrasion, the Dorman metal connector resists heat-related embrittlement and mechanical wear. That means fewer repeat repairs and a more dependable seal under system pressure.

• Constructed from rugged metal for improved impact and abrasion resistance.
• Pressure-tested to validate leak-free performance under operating conditions.
• Designed to match OE geometry for correct hose routing and clamp placement.

What should I expect during installation?

Installation is a direct replacement procedure: remove the failed plastic connector, clean hose ends, slide on proper clamps, and install the Dorman metal connector in the original orientation. Basic hand tools are usually sufficient; follow manufacturer torque and clamp recommendations for a secure seal.

• Remove coolant or relieve pressure as required by your vehicle service manual.
• Inspect heater hoses and replace any that are cracked or weakened before installing the new connector.
• Use corrosion-resistant hose clamps tightened to recommended specifications for best results.

Which vehicles commonly use this heater hose connector?

This OE FIX part fits a broad group of models across multiple manufacturers—primarily early-2000s GM SUVs, mid-decade Fords, later Chrysler/Dodge minivans and current Jeep Wagoneer/Grand Wagoneer models among others. Always confirm year and trim in the fitment tool to avoid ordering errors.

• Examples include Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Ford Fusion/Ford Focus models.
• Dodge Grand Caravan and a range of Ram trucks and Chrysler Town & Country years are covered.
• Newer Jeep Wagoneer/Grand Wagoneer and certain Lincoln models are included—verify fit first.

Who is this for: The Dorman 800-418HP is ideal for DIY enthusiasts and professional technicians who want a more durable replacement than the OEM plastic heater hose connector. If you’re repairing a leaking or broken heater hose connection and prefer an OE-style fit with greater resistance to heat and abrasion, this metal OE FIX connector provides a simple, longer-lasting upgrade that helps prevent the need for repeat repairs.
