A connector assembly includes a first connector, a compression member, a retainer, and a second connector. The first connector includes a first coupling portion, a proximal opening, and an annular inner surface extending from the proximal opening. The compression member includes an inner surface and an outer surface. The outer surface is configured to sealingly engage the annular inner surface of the first connector. The retainer includes a ring portion and a plurality of teeth. The ring portion includes a proximal end and a distal end. Each of the plurality of teeth extends from the distal end and is configured to engage the compression member. The second connector includes a second coupling portion and an engagement surface. The second coupling portion is configured to engage the first coupling portion. The engagement surface is configured to engage the proximal end of the retainer.

A conduit clamping and sealing system includes: a bearing element including: a back segment with an external back thread for attaching to a device or fastening to a box or enclosure; a middle segment for receiving a conduit and guiding and/or aligning a hygienic sleeve system; and a front segment for receiving a seal, and a front nut for sealing a connection between the conduit and the bearing element and fastening the hygienic sleeve system.

A vehicle shifter mechanism comprises a shift control member configured with an outer threaded portion proximate an upper end, and an inwardly tapered bore proximate the upper end. A shift lever is configured with an outwardly extending annular shoulder proximate a lower end. The annular shoulder has a tapered lower portion configured to register with the tapered bore of the shift control member. A locking nut is configured to fit over the shift lever and to mate with the threaded portion of the shift control member to compress the tapered lower portion of the annular shoulder to the tapered bore to fix the shift control member to the shift lever.

A liquid-tight fitting includes a connector, a seal, and a fastener member. The connector has a first and a second end, a shoulder located between the first and second ends, and a segment that extends from the shoulder to the first end. The segment has an outer surface. The seal has an inner surface in contact with the outer surface of the segment, an outer edge, and first and second seal ends joining the inner surface and the outer edge. The seal surrounds a portion of the segment such that the first seal end abuts against the shoulder. The fastener member is moveably secured to the first end of the connector, and has an end that engages the second seal end to cause the seal to compress between the shoulder and the fastener member. The seal member is adapted to deform toward the segment when compressed.
