Four Seasons A/C Orifice Tube P/N:623 (Pack of 10)
Four Seasons 635 front a/c orifice tube for the 1991-2010 Ford Explorer and other vehicles is the fixed-diameter tube that divides the high-pressure and low-pressure sections of the A/C system.
The orifice tube also works as a refrigerant filter, so debris can clog it, and a clogged one is always replaced. Weak cooling at the vents can come from a clogged tube or from other A/C faults, so with the engine off, look over the lines and fittings for oily residue first and leave pressure testing to a shop.
Among the vehicles it fits are the 1987-1998 Ford F-150 and the 1998-2011 Ford Ranger. If your truck or van is not named here, look up its year, make, model and engine in the "Vehicles it fits" section.
