Dorman Metal 90° Heater Hose Connector 3/4 x 3/4 — OE FIX Durable Metal Replacement for GM Ford Dodge Jeep

Dorman's 800-418HP is a 3/4" x 3/4" 90° metal heater hose connector designed as a long-lasting OE FIX replacement for vehicles originally fitted with fragile plastic HVAC hose fittings.

If the original plastic heater hose connector on your vehicle has become brittle, cracked, or started leaking, this Dorman metal connector offers a robust upgrade. Built to match the original geometry for easy installation while using metal construction to resist heat and abrasion, it aims to extend service life and reduce repeat repairs. Confirm fitment with your vehicle trim using the garage tool before ordering.

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

The Dorman OE FIX connector replaces the plastic fitting with a rugged metal body that tolerates engine-bay heat and rubbing better than the factory plastic. That improved durability lowers the chance of hairline fractures and hose separation that commonly cause coolant or HVAC leaks.

• Metal construction resists heat and abrasion compared with plastic
• Pressure-tested design to ensure reliable performance under system pressure
• Same dimensions as the factory part for direct replacement

Will this connector fit my vehicle and is installation straightforward?

This connector is manufactured to precise specifications so it installs like the original part on compatible models. Always enter your vehicle details in the garage tool and check the Confirmed Fit indicator; some listings show an information icon that requires additional verification.

• Direct-replacement geometry simplifies swap-in installation
• Compatible with many GM, Ford, Dodge, Chrysler, Jeep and Lincoln models—verify with the fit tool
• Works with standard 3/4" heater hoses and clamps used on listed vehicles

Which cars and years are supported by this Dorman heater hose connector?

This OE FIX connector covers a range of older GM SUVs, mid-2000s Fords, several recent Jeep/Wagoneer models, many Dodge/Chrysler minivans and Ram trucks, plus select Lincoln, Oldsmobile and Saab models. Always verify your exact trim and year before purchasing to ensure compatibility.

• Examples include Chevrolet Trailblazer (2002–2006) and Blazer (2002–2005)
• Dodge Grand Caravan (2011–2020) and multiple Ram heavy-duty years (2007–2010)
• Ford Focus/Fusion/C-Max (2012–2020 ranges) and Lincoln MKZ/Continental listings

What should I expect in terms of longevity and maintenance?

Because the connector is made from metal and pressure-tested during development, you can expect a more durable repair compared with replacing like-for-like plastic fittings. Normal maintenance remains the same: inspect hoses and clamps for wear and tighten or replace clamps as needed to prevent leaks.

• Reduced risk of heat- and abrasion-related failures
• Maintain hose clamp torque and inspect hoses during routine service
• Pressure-tested to help ensure dependable sealing after installation
