Spin-on filter for suction-side and pressure-side applications in filtration systems

A filtration system comprising:

• a filter mounting head including a circumferential groove;
• a filter housing coupled to the filter mounting head through a threaded connection, the filter housing having an open end and a closed end;
• a filter element positioned within the housing and configured to filter a fluid, the filter element is positioned in a pressure-side application within the filtration system;
• an endcap positioned adjacent to the open end of the housing, the end cap is coupled to a first end of the filter element;
• and
• a seal coupled to the endcap and configured to seal a clean side of the filter element from a dirty side of the filter element, the seal including an outer sealing ridge that at least partially engages the circumferential groove, wherein a pressure of the fluid flowing through the filtration system bends the outer sealing ridge against an outer surface of the circumferential groove to form a seal.
