GM Genuine Parts 15-5378 (03096068) Air Conditioning Condenser Orifice

The orifice tube Is a very low priced component but it is also an extremely important part of the AC system. It serves two purposes, it filters out most contaminants from the oil and liquid refrigerant and also provides the correct pressure differential that is crucial to the proper and efficient performance of an air conditioning system. A partially clogged orifice tube will not provide the proper reduction of refrigerant pressure which will translate in inefficient cooling of passenger compartment air and increased strain on the compressor and other components. A severely or completely obstructed orifice tube will inevitably result in compresor failure. Before recharging your AC system always replace the orifice tube, the few "extra" dollars spent and minimal additional repair work will go a long way towards ensuring the system operates as efficiently as it can operate and lasts as long as it should last. This orifice tube fit my 2003 GMC Yukon XL with rear AC perfectly. I understand there are two different sizes of orifice tubes and newer or different trucks use the "2nd design", which is larger in diameter. The outside diameter of the AC line where the (1st design) orifice tube is housed on my truck is exactly .500", if the line is larger than that, it means it takes the "2nd design" orifice tube. Overall I'm satisfied wit the quality of this AC Delco part, and recommend it to any one planning to work an air conditioning system. I have attached a picture of the orifice tube removed, which shows significant obstruction caused by very fine metal shavings. An important word of caution, i f you intent to work on your AC and if the system is still pressurized, please take it to a professional shop an have the system purged or drained by a professional certified technician using the correct equipment and procedures.

Worked perfectly on our 2002 Chevy Suburban with the rear A/C option.

Perfect fit, direct replacement for my 2003 Tahoe. GM is the only way to go.

Excellent part.

Good price

This product I am sure is fine - however I ordered for a 2006 Yukon XL SLT with rear air. It does not fit this vehicle even though the fitment denotes it does. After researching this product it only fits a only Generation (1) systems and my year Yukon has a Generation (2) system - which is a larger and much different orifice tube. So do your homework first before ordering. Amazon as always took the item back and issued a refund without an issue.

Found this item at a great price last minute. Will definitely be back

After cleaning my ac system from a compressor that blew up, replaced all ac components including compressor, this works perfect and blows colder than my 80k mile 2012 gmc sierra.
