Four Seasons 639 front a/c orifice tube for the 2001-2007 Ford Escape and other vehicles divides the high-pressure and low-pressure sections of the A/C system with a fixed-diameter tube.
- Engineered and tested for trouble-free operation, with over 50 years of mobile A/C experience behind it.
- Includes the o-rings and gaskets needed to seal high pressure from low pressure.
- Application-specific direct-fit replacement, for easier installation.
- Injection-molded, color-coded plastic for easy identification.
- No moving parts: refrigerant simply flows through the fixed-diameter tube.
- Built to the OEM size and color for each application.
An orifice tube also acts as a refrigerant filter, so it can clog with debris, and a clogged one always needs to be replaced. Weak cooling at the vents can mean the tube is clogged. Poor cooling alone doesn't prove the tube is the problem, since a low refrigerant charge is another common cause.
This orifice tube fits the 1991-2006 Ford Mustang and the 2000-2007 Ford Focus, along with many other vehicles.

Frequently Asked Questions
Does the Four Seasons 639 orifice tube fit the 2001-2007 Ford Escape?
Yes, Four Seasons 639 is a direct-fit replacement for the 2001-2007 Ford Escape. For another car or for engine details, look up your own vehicle in the "Vehicles it fits" section.
How many orifice tubes come in the Four Seasons 639 pack?
Four Seasons 639 is a 10-pack of orange orifice tubes. The pack contains the o-rings and gaskets needed to seal high pressure from low pressure.
Why is this orifice tube orange?
The tube is injection-molded, color-coded plastic, which makes it easy to identify. Orifice tubes are built to the OEM size and color for each application.
Can a clogged orifice tube make my A/C cool poorly?
It can. This tube also filters refrigerant, so debris can clog it, and a clogged one has to be replaced. A shop can test the A/C system to find the actual cause.
Does an orifice tube have any moving parts?
No. It's a simple fixed-diameter tube, and refrigerant flows straight through it as it separates the high-pressure and low-pressure sections of the system.
