Four Seasons A/C Orifice Tube P/N:8623 (Pack of 25)
Meter refrigerant between the high- and low-pressure sides of your A/C system with the Four Seasons A/C Orifice Tube 8635. It installs in the front orifice tube position as an application-specific, direct-fit replacement for a long list of Ford, Lincoln and Mazda vehicles — including the 1986-1989 Ford Aerostar, 1991-2010 Ford Explorer, 1987-1998 Ford F-150, 1995-2003 Ford Windstar, 1998-2002 Lincoln Navigator and 1994-2008 Mazda B3000. See the Buyer's Guide tab for the full list of 156 applications and the engine details for your vehicle.
Because the orifice tube also acts as a refrigerant filter, it can collect debris over time and become clogged, so it should be replaced whenever the A/C system is serviced. Backed by over 50 years of mobile A/C experience from Four Seasons.

This part cross-references / interchanges with the following part numbers:
What does an A/C orifice tube do?
It serves as the divide between the high- and low-pressure sections of the A/C system, letting refrigerant flow through its fixed-diameter tube. It has no moving parts and also acts as a refrigerant filter.
Does this orifice tube include the seals?
Yes. It contains the o-rings and gaskets needed to seal the high-pressure side from the low-pressure side of the system.
Why should the orifice tube be replaced during A/C service?
Since it acts as a refrigerant filter, it can become clogged with debris over time, so it should always be replaced when the A/C system is serviced.
Will this fit my vehicle?
It's an application-specific, direct-fit orifice tube for the listed Ford, Lincoln and Mazda applications. Check the Buyer's Guide tab to confirm the fit for your exact year, make and model.
How can I identify the correct orifice tube?
Four Seasons uses injection-molded, color-coded plastic built to the application-specific OEM size and color for easy identification. Match it to your vehicle in the Buyer's Guide.
