What the AI looks for in Automotive Replacement Air Conditioning Orifice Tubes
- System type
- Orifice tubes are used only in accumulator (orifice-tube) systems, not expansion-valve systems If your car has a TXV and a receiver-drier, it has no orifice tube.
- Size match
- Match the OEM orifice size; tubes are color-coded by size, but codes vary by maker, so match by part number The wrong orifice size overfeeds or starves the evaporator.
- Replace on compressor failure
- Always replace it with the accumulator after a compressor failure The screen traps debris and is often clogged.
- Removal
- Use a proper orifice-tube removal tool; a broken tube needs an extractor or a line repair kit Seized tubes snap easily.
Brands that matter
- Four Seasons: OE-sized orifice tubes and removal tools.
- Santech: Orifice tubes by application.
- Motorcraft: OE orifice tubes for Ford.
- ACDelco: OE orifice tubes for GM.
What to avoid
- Choosing an orifice size by color alone across brands
- Reusing a clogged or debris-filled orifice tube
