Flare Receiver Drier

Standard flare receiver drier used on most aftermarket flare a/c systems.  The drier has 3/8" male flare fittings,  5/8"-18 Threads, and two female switch ports on opposite sides of the drier.
The drier measures 2-1/2" x 8" tall, and has a sight glass on the top for R-12 systems.
The drier can be used with all refrigerants.

Below is an explanation of the driers operation, and why they should be changed.

The drier is used on many a/c systems. It receives refrigerant from the condenser. The drier is mounted either adjacent to the condenser or somewhere in line before the expansion valve. It consists of a tank, a filter, a drying (agent) desiccant, a pick up tube, and a sight glass (on some applications), the drier has several functions.
First the drier acts as storage tank. It receives the liquid refrigerant from the condenser and holds this liquid until the evaporator requires it. Requirements vary according to operations conditions.
Second the drier acts as a protection agent for the system. The portion of the drier that contains the desiccant absorbs moisture from the refrigerant. The desiccant is usually in the form of silica gel. It is important that the moisture be removed from the system, as it can be extremely harmful to the air conditioning system components and to the systems operation.
The sight glass is not used with R-134a, it was used on vehicles made before 1994 that used R-12 freon.
