Dorman 626-721 HVAC Heater Hose Assembly - Inlet
Dorman 626-721 Heater Hose Assembly
Dorman 626-721 is a replacement HVAC heater hose assembly for select Ford F-150 and Lincoln Mark LT applications. It is built to match the original hose assembly’s fit and durability, with materials selected to handle repeated temperature swings in the heater circuit.
- Replacement HVAC heater hose assembly for the heater system
- EPDM and plastic construction for heat and coolant exposure
- Black molded assembly with a protective sleeve attached
- Quick disconnect ends on both sides for OE-style connection points
- Standard replacement grade for select inlet hose applications
- Maximum working pressure: 100; burst pressure: 75
- Centerline length: 581.8; maximum bend angle: 135
Fitment Details
Compatible with 2011-2014 Ford F-150, inlet hose assembly. Compatible with 2011-2014 Lincoln Mark LT, inlet hose assembly. This part cross-references Dayco 72728 and Gates 51338 for the same application.
Built for Heater Circuit Service
This HVAC heater hose assembly is designed around OE-style routing and connection points, making it a direct replacement for the inlet side on the listed vehicles. The molded hose shape, quick disconnect ends, and protective sleeve help it follow the factory path while maintaining a secure connection in the heater system. Dorman 626-721 is a practical choice when replacing a worn or damaged heater hose on a 2011-2014 Ford F-150 or 2011-2014 Lincoln Mark LT.
What It Helps Fix
- Coolant leaks from cracked or aged heater hose material
- Loss of heater performance caused by restricted coolant flow
- Broken or weakened quick disconnect connections
- Heat-related hose deterioration from repeated temperature cycling
- Fitment issues after replacing a factory inlet heater hose assembly
Installation Notes and Tips
Verify the inlet position and connector style before installation. Inspect the mating ports, seals, and surrounding coolant lines for wear or contamination before connecting the new assembly. Because this hose uses quick disconnect ends, confirm that the factory-style retainers and seals are fully seated during installation.
Quality Assurance
Dorman engineers this heater hose assembly to match the fit and durability of the original equipment part on the specified vehicles. The EPDM and plastic construction is selected to withstand extreme temperature changes for extended service life.
