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.
Claims20
A torque-limiting fitting comprising:
- a driven coupler including:
- a sealing region;
- and
- a plurality of driven teeth located on a circular end surface that is orthogonal to a central axis of the driven coupler and including, in a sealing direction of the driven coupler, a sloped rotationally trailing surface;
- and
- a driving collar including:
- a plurality of driving teeth positioned to engage with the plurality of driven teeth as the driving collar is rotated,
- wherein at least one driving tooth of the plurality of driving teeth includes a substantially flat portion that is orthogonal to the central axis of the driven coupler, and
- wherein the substantially flat portion is engageable with a corresponding flat portion between adjacently disposed driven teeth.
A torque-indicating fitting comprising:
- a driven coupler including a plurality of driven teeth located on a circular end surface that is orthogonal to a central axis of the driven coupler;
- and
- a torque-indicating driving collar including:
- a plurality of driving teeth positioned to engage with the plurality of driven teeth as the torque-indicating driving collar is rotated;
- and
- at least one torque-indicating tooth positioned adjacent to at least one driving tooth to engage with at least one driven tooth as the torque-indicating driving collar is rotated,
- wherein the at least one driving tooth of the plurality of driving teeth includes a substantially flat portion that is orthogonal to the central axis of the driven coupler, and
- wherein the substantially flat portion is engageable with a corresponding flat portion between adjacently disposed driven teeth.
A torque-limiting fitting comprising:
- a driven coupler including:
- a sealing region;
- and
- a plurality of driven teeth located on a radially outer surface of the driven coupler and including, in a sealing direction of the driven coupler, a sloped rotationally trailing surface;
- and
- a driving collar including:
- a plurality of driving teeth positioned to engage with the plurality of driven teeth as the driving collar is rotated,
- wherein at least one driving tooth of the plurality of driving teeth includes a portion that is orthogonal to a central axis of the driving collar, and
- wherein the portion is engageable with a corresponding portion between adjacently disposed driven teeth.
