Filter housing
View Patent ↗A filter housing has a large diameter body with texturing which facilitates tightening without a wrench, although wrench hex flats are provided for the last quarter turn. An integral weather seal is incorporated into the filter housing to eliminate the possibility of installing the wrong seal, improperly installing the correct seal, or omitting the installation of any seal at all.

a third portion of the outer body having a smooth surface effective to permit affixing indicia thereon;
an integral weather seal mounted onto a portion of the inner body;
wherein the inner body includes a plurality of slots therein, and a circuit board is mounted in the slots;
a male contact connected to one side of the circuit board;
a female contact connected to another side of the circuit board;
a first insulator affixed over a portion of the male contact;
a second insulator affixed over the female contact;
the second insulator including a rim with a section of the second insulator between the rim and a free end of the second insulator; and
