School Bus Filter-Drier Fittings

Note that there are (2) types of "Flare" fittings.  the one shown at right comes with a tiny O-Ring that fits in a groove on the flare.....and this type can be used in place of the plain flare shown at left.



There are (2) types of "Internal O-Ring" fittings.  It helps if we know if the drier you need has the LH or the RH version. 

Note:  The Internal O-Ring Drier on the right is commonly used with Thermo-King systems.

It also helps us identify the Filter-Drier you need if you can tell us what your old part looks like.  The following diagram will help.
