Abstract: A filter cap for a body of a refrigerant tank of an automotive HVAC device is provided. The filter cap includes a main body having a rim defining an opening for allowing flow of fluid such as refrigerant. A collar is snap-fit to the cap at the rim. In various embodiments, the collar has a flexible finger that flexes during assembly to the rim, and snaps back into position when fully pressed about the rim. The collar contains a filter membrane between the rim and the collar. The collar has an upper structure such as a plurality of spaced-apart legs. This allows the collar to protect the filter membrane from potential damaging contact while still enabling proper fluid flow through the filter membrane.

Abstract: A bracket for mounting a heat exchanger to a mounting structure. The bracket includes a heat exchanger engagement portion having a heat-shrink material configured to contract and shrink onto a portion of the heat exchanger when heated to secure the heat exchanger engagement portion to the heat exchanger. A mounting portion extends from the heat exchanger engagement portion and is configured to be affixed to the mounting structure to rigidly mount the heat exchanger.
