Abstract
In some examples, a filter assembly may include a filter including a first gasket having a first channel adjacent to a first side of the filter and a second gasket having a second channel adjacent to a second side of the filter. The first gasket and the second gasket may include a beveled surface adjacent to the filter. The first channel and the second channel may include a diameter of from about 0.01 mm to about 0.5 mm. A finger tightening system may securely hold the filter without any leaks.
Claims14
A filter assembly comprising:
- a filter;
- a first gasket adjacent to a first side of the filter;
- a second gasket adjacent to a second side of the filter, wherein at least one of the first gasket or the second gasket includes a conically shaped beveled surface adjacent to the filter, wherein the conically shaped beveled surface includes a conical profile extending from first and second channels respectively of the first and second gaskets, wherein the conically shaped beveled surface is configured to provide a gap between at least one of the first gasket or the second gasket and the filter when at least one of the first gasket or the second gasket is disposed in an assembled configuration relative to the filter, and wherein an outermost diameter of at least one of the first gasket or the second gasket is substantially the same as an outermost diameter of the filter;
- a female housing;
- and
- a male housing;
- wherein:
- the male housing is sized to fit concentrically within the female housing;
- each of the male housing and female housing include:
- a bore;
- and
- a stop shoulder surrounding the bore;
- and
- each of the first gasket and second gasket include a complementary geometry to form a seal against a respective stop shoulder.

A filter assembly comprising:
- a filter;
- a first gasket having a first channel adjacent to a first side of the filter;
- and
- a second gasket having a second channel adjacent to a second side of the filter, wherein the first gasket and the second gasket include conically shaped beveled surfaces adjacent to the filter, wherein the conically shaped beveled surfaces are configured to provide gaps between the first gasket and the second gasket and the filter when the first gasket and the second gasket are disposed in an assembled configuration relative to the filter, and wherein outermost diameters of the first gasket and the second gasket are substantially the same as an outermost diameter of the filter, and
- wherein the first channel and the second channel include a diameter of from about 0.01 mm to about 0.5 mm.

A guard column assembly comprising:
- a first filter;
- a second filter;
- a media positioned between the first filter and the second filter;
- a first gasket having a first channel adjacent to the first filter;
- and
- a second gasket having a second channel adjacent to the second filter,
- wherein the first gasket and the second gasket include conically shaped beveled surfaces adjacent to the first filter and the second filter, respectively, wherein the conically shaped beveled surfaces are configured to provide gaps between the first gasket and the filter, and the second gasket and the second filter when the first gasket and the second gasket are disposed in an assembled configuration relative to the first filter and the second filter, and wherein outermost diameters of the first gasket and the second gasket are substantially the same as outermost diameters of the first filter and the second filter, respectively, and
- wherein the first channel and the second channel include a diameter of from about 0.01 mm to about 0.5 mm.
