An expandable gasket, spreader mechanism, and rotating gripper seal mixed pipe diameters while simplifying installation and reducing leaks.

A two-piece retainer locks the tube with lower insertion force, no post-process machining, and tool-free assembly without loose clips.

Pressing pins and an adjustable band keep pipe ends tightly coupled during high-pressure unclogging, reducing leakage and separation.

A bayonet retainer collar captures connector lugs to secure aircraft fuel pipe joints under wing flex while cutting extra fasteners.

An inclined engagement surface pre-centers interleaving jaws so a wire-driver chuck can quickly clamp small or angled shafts accurately.

Pre-compressing the seal and guiding the skirted interface eases pipe-to-opening assembly while preserving alignment and leak-tight sealing.

By moving the sealing ring into a drain-body groove, this case prevents seal displacement and allows odor trap insertion and repositioning.

A bonded polypropylene-EPDM gasket uses a rigid reinforcement band to stay seated in ductile iron pipe grooves and resist blow-out under pressure.

An integrated band, nut, and washer clamp prevents deformation during bolt tightening, improving fastening force, reuse, and part count.

Spherical locking elements and matching grooves stop rotary tool axial migration in thermally expandable chucks, improving machining accuracy and safety.

A control sleeve actuates a pawl-and-toothed-ring ratchet so chuck jaws stay locked against loosening in either rotation direction.

A movable sleeve bridges angled connector parts so standard clamps can form fluid-tight joints where direct push-fit assembly is impractical.

Bearing-ring pipe couplings let pipeline sections rotate without disconnection, reducing uneven wear, fluid loss, and maintenance effort.

A branched coupling combines threaded ends, internal branch ports, seals, and a plug cap to speed compressed air pipe connection without tools.

A two-collet chuck separates axial motion from radial gripping to prevent workpiece pull-in, improve centering, and ease collet replacement.
