Ford F Super Duty A/C Manifold Hose Assemblies
Ford F Super Duty A/c manifold hose assemblys
Starting at $106.95, AutoBuffy stocks 2 A/C manifold hose assemblies from UAC, so you can find a direct-fit replacement for your Ford F Super Duty without piecing together separate hoses and fittings. This assembly connects the compressor, condenser, and evaporator, routing refrigerant through the entire system. When it cracks, kinks, or leaks at a fitting, refrigerant escapes and your A/C stops cooling.
Signs your Ford F Super Duty needs a new A/C manifold hose assembly
- Warm air blowing from the vents even after the system has been recharged with refrigerant
- Visible oily residue or greasy film along the hose body, at crimped fittings, or around O-ring seats — refrigerant oil escapes wherever refrigerant leaks
- A/C system loses charge repeatedly within days or weeks of being recharged at a shop
- UV dye inspection or electronic leak detector pinpoints the hose assembly — not the compressor, condenser, or evaporator — as the leak source
- Hose outer jacket shows cracks, bubbling, abrasion wear, or is physically collapsed or kinked from heat or contact with engine components
- Hissing or faint bubbling sound near the firewall or compressor when the A/C clutch engages, indicating refrigerant escaping under pressure
Which A/C manifold hose assembly should you buy for your Ford F Super Duty?
A/C manifold hose assemblies are sold as complete pre-crimped units that include the hose sections, steel or aluminum manifold block, and all fittings — the main decision is grade and whether the assembly covers the high-pressure side, low-pressure side, or both in a combined unit. Fit is critical: threads, O-ring seat sizes, and block port orientation are vehicle-specific, so confirm the part matches your Ford F Super Duty's configuration before ordering.
OE-Equivalent Replacement
Best for
Restoring factory performance with a guaranteed direct fit
What you get
Hose and fittings engineered to OE dimensions, pre-crimped ends, correct block angle — no modifications needed
High-Side (Discharge) Assembly
Best for
Replacing only the compressor-to-condenser high-pressure hose when the low-side is still in good condition
What you get
Heavy-wall barrier hose rated for high refrigerant pressure, with the correct discharge port fittings for your Ford F Super Duty
Low-Side (Suction/Liquid) Assembly
Best for
Replacing only the evaporator-to-compressor or condenser-to-evaporator low-pressure hose
What you get
Larger-diameter barrier hose for low-pressure refrigerant flow, pre-fitted with suction-side manifold block and O-rings
Premium / OEM-Brand Assembly
Best for
High-mileage vehicles, fleets, or owners who want the longest service life
What you get
Thicker barrier hose construction, stainless or heavy-gauge aluminum fittings, full O-ring kit included — reduces risk of repeat leaks

After a certified shop has evacuated the refrigerant from your Ford F Super Duty's system, route the new assembly along the same path as the original, avoiding contact with exhaust or sharp edges. Replace every O-ring at every fitting connection using lubricated new O-rings supplied with or matched to the assembly — reusing old O-rings is the most common cause of a repeat leak. Once installed and torqued snugly at each fitting, have the system pressure-tested, pulled to a deep vacuum, and recharged by a certified technician before running the compressor.
Frequently asked questions
How much does it cost to replace A/C manifold hose assemblies on a Ford F Super Duty?
The part alone starts at $106.95 for your Ford F Super Duty. Add shop labor — typically one to three hours at local rates — plus the cost of evacuating and recharging the refrigerant, which shops charge separately. Doing the hose swap yourself saves on labor, but refrigerant recovery still requires certified equipment.
Can I drive my Ford F Super Duty with a leaking A/C manifold hose assembly?
Yes, a refrigerant leak won't strand you or damage the engine, but you should not ignore it. Once refrigerant is fully depleted, the compressor may run without lubrication — refrigerant oil circulates with the refrigerant — which can seize the compressor and turn a hose replacement into a far more expensive repair.
Do I need to replace both the high-side and low-side hose assemblies at the same time on my Ford F Super Duty?
Only if both are leaking or visibly degraded. Inspect each section individually with UV dye or an electronic leak detector. If only one side is the source, replace that assembly. However, if the hose is original and high-mileage, replacing both during the same refrigerant evacuation saves labor and future recharge costs.
What refrigerant type does my Ford F Super Duty use, and does it affect which hose assembly I buy?
The refrigerant type — most commonly R-134a or the newer R-1234yf — determines the hose barrier layer and O-ring material required. R-1234yf systems use hoses with a specialized inner liner. Always confirm your Ford F Super Duty's refrigerant type on the underhood A/C label and match it to the hose assembly specification before purchasing.
Is replacing an A/C manifold hose assembly on a Ford F Super Duty a DIY job?
The hose swap itself is a moderate DIY task, but legally you must have refrigerant recovered by a certified technician before opening the system — you cannot vent refrigerant to the atmosphere. Once the system is evacuated, most home mechanics can swap the assembly, replace O-rings, and have a shop pull a vacuum and recharge when finished.
How long do A/C manifold hose assemblies typically last on a Ford F Super Duty?
Most OE-quality A/C hose assemblies last anywhere from ten to fifteen or more years under normal conditions, but lifespan shortens with heat cycling, ozone exposure, and physical contact with hot engine components. Hoses on high-mileage vehicles often harden or crack at the fittings first. Inspect them whenever the A/C system is serviced.
