Move high-pressure liquid refrigerant from the condenser toward the expansion device with the Four Seasons A/C Refrigerant Liquid Hose (P/N 56576). This application-specific liquid line is a direct-fit replacement for the 1997 Ford Explorer (V6-4.0L and V8-5.0L) and the 1997 Mercury Mountaineer (V8-5.0L), routing refrigerant on the high-pressure side of the system.
- Orifice tube pre-installed: the fixed orifice tube is already installed in the aluminum pipe section — no separate orifice tube is needed to complete the job.
- Double-wall barrier hose: compatible with R-1234yf, R-134a, or R-12; this application is listed for R-134a.
- Construction: aluminum and rubber build with crimp fitting connections at the hose ends.
- End fittings: End 1 is a P-Nut fitting and End 2 is a Male Springlock.
- Fittings and seals included: comes with the gaskets, O-rings, or seals and the fittings needed to complete the replacement. No bracket, service port, or switch port is included.
Application-specific design backed by Four Seasons’ decades of mobile A/C experience. If a leaking or damaged liquid line is the cause of poor cooling, this replaces it; diagnose the cause first, as refrigerant loss can have other sources. Four Seasons part number 56576.

Frequently Asked Questions
What does the Four Seasons 56576 liquid hose do?
It's the liquid line that carries high-pressure liquid refrigerant from the condenser toward the expansion device and evaporator in the A/C system.
Does it come with the orifice tube, or do I need to buy one separately?
It comes with a fixed orifice tube already pre-installed in the aluminum pipe section — you do not need to buy a separate orifice tube for this line.
Which vehicles does P/N 56576 fit?
1997 Ford Explorer (V6-4.0L and V8-5.0L) and 1997 Mercury Mountaineer (V8-5.0L). See the "Vehicles it fits" section to confirm your exact application.
What refrigerant is this hose compatible with?
Its double-wall barrier hose is compatible with R-1234yf, R-134a, or R-12; this application is listed for R-134a.
Does it include O-rings and fittings, and how do I know the line needs replacing?
Yes — it includes the gaskets, O-rings, or seals and the fittings needed (no bracket/service/switch port). Signs it needs replacing: refrigerant leaks or oily residue at the crimp fittings with reduced cooling; diagnose first.
