GUIDE TO ACCUMULATOR FITTINGS

Components in an air conditioning system require a clean, non-corrosive environment. Moisture is corrosive to air conditioner system components and must be eliminated for efficient a/c system operation. Any time the a/c system is opened, the accumulator and orifice tube need to be replaced. A good preventative maintenance practice is to replace the accumulator / orifice tube at regular intervals (at least once a year). A/C compressor manufacturer’s warranties will be void without proof of flushing the system, accompanied by replacement of the accumulator and orifice tube when replacing a compressor.

Accumulators have a variety of con- necting fittings, often connected to tubing designed for a specific application. Here are the different types of fitting connections you will experience while working with accumulators.
