USA service part for the 77-84 GM Vehicles. This is the Filter Dryer or Accummator as some call it.  As GM has now discontinued many  the Dryers/ Accumulator .... this is as good or better a design you will find to replace the original.. its general in use so look at the outlets... especially on converted/ modified RH drive cars.

• Compatible with both R134a and R12 refrigerants
• Contains gaskets, o-rings, or seals to properly replace the product
• Contains high quality XH9 desiccant
• High quality welds ensure durable, leak free design

Fits correctly but do look close as RH drive conversions.. who knows whats been fitted.
