Keep refrigerant metering where it belongs with the Four Seasons A/C Orifice Tube 621, a front-position, application-specific direct-fit replacement. It drops into the listed Ford applications — including the 1980-2004 F-150, 1980-2004 F-250, 1980-2004 F-350, 2008-2010 Explorer, 1981-1990 Escort, 1982-1990 and 2007-2009 Mustang, and 1986-1990 Taurus. This part covers 149 applications, so see the "Vehicles it fits" section for the full list.
An orifice tube serves as the divide between the high- and low-pressure sections of the A/C system. It is a very simple component with no moving parts, letting refrigerant flow through its fixed-diameter tube. Because it also acts as a refrigerant filter, it can become clogged with debris, which is why the orifice tube should always be replaced during service.
- Seals included: contains the o-rings and gaskets necessary to seal high pressure from low pressure.
- Easy ID: injection-molded, color-coded plastic (blue) for quick identification.
- Application specific: built per OEM size and color for ease of installation.
- Quality components: high-quality parts for long-lasting performance.

Frequently Asked Questions
What does this orifice tube do?
It forms the divide between the high- and low-pressure sides of the A/C system, metering refrigerant through a fixed-diameter tube with no moving parts.
Does it come with o-rings and gaskets?
Yes. It contains the o-rings and gaskets necessary to seal high pressure from low pressure for the installation.
Why is it color-coded blue?
Four Seasons injection-molds orifice tubes in color-coded plastic per OEM size and color, so the correct application-specific tube is easy to identify.
Should I replace the orifice tube during A/C service?
Yes. Because the orifice tube also acts as a refrigerant filter, it can become clogged with debris, so it should always be replaced during service.
Will this fit my vehicle?
It is an application-specific direct-fit replacement covering 149 Ford applications. Check the "Vehicles it fits" section to confirm it matches your exact vehicle.
