Meter refrigerant flow between the high- and low-pressure sides of your air conditioning system with the Four Seasons A/C Orifice Tube (MPN 8623). It drops in as an application-specific, direct-fit replacement across a wide range of vehicles — including the 1976-1986 Chevrolet C10, 1977-1998 Buick Century, 1977-2005 Cadillac DeVille, 1984-1988 Audi 5000, and 1985-2001 Chevrolet Astro (All engines) — with 257 applications in total; see the Buyer's Guide tab for the full list. This is the front-position orifice tube for the listed applications.
- Divides high and low pressure: a simple fixed-diameter tube with no moving parts that lets refrigerant flow through at a set rate.
- Seals included: comes with the necessary o-rings and gaskets to seal the high-pressure side from the low-pressure side.
- Easy to identify: injection-molded, color-coded white plastic, built application-specific per OEM size and color.
- Backed by experience: engineered and tested by Four Seasons, drawing on over 50 years of mobile A/C experience.
Because the orifice tube also acts as a refrigerant filter, it can become clogged with debris, so Four Seasons recommends always replacing it during A/C service. Supplied in a 25-count package per the manufacturer label.
