Abstract: A hose and quick connect coupling assembly comprising a receiving hose, an insertion hose, a pair of quick connect coupling halves each coupling half being identical to the other, and a securing clasp. The securing clasp releasably secures the coupling halves around the receiving hose, thereby forming a releasable coupling as the insertion hose in inserted into the receiving hose. The insertion hose may be removed by depressing the coupling halves together, causing the top portions thereof to pivot away from the insertion hose. The securing clasp may also be removed from the hose coupling, thereby removing the coupling halves from the receiving hose.

Abstract: A 90° swivel connector capable of rotating 360° has threads on one end that screw into a threaded hole in a boss on a compressor portion of a turbocharger and has barbs on the other end of the swivel connector for receiving and retaining a hose. The 360° rotation enables alignment of the swivel connector with the hose to prevent kinking of the hose when the relative angular position of the connector and hose is varied to facilitate diverse engine usage.

Abstract: The invention relates to a swivel adapter-coupler that is to be positioned between a conventional fixed drop elbow on the end of a hose of a tanker truck for an underground storage tank. The other end of the swivel adapter-coupler attaches to the pipe adapter (either the fill pipe or the vapor pipe) of the underground storage tank, in the conventional quick-connect type connection. The swivel adapter-coupler permits loops and kinks in the hose to be removed by rotating the swivel adapter-coupler in the proper direction. Likewise, the invention relates to a rotatable drop elbow to replace the conventional fixed drop elbow at the end of a hose on a tanker truck. The rotatable drop elbow eliminates loops and kinks in the hose by merely rotating the drop elbow in the proper direction.

Abstract: A windshield cleaning system with a washing system includes a washing liquid pipe non-rotatably fixed in a bore of a wiper shaft, the end of which washing liquid pipe is inserted into a pot-like connecting piece protected against twisting. Thereby the connecting piece is bracelessly centered with respect to the end of the washing liquid pipe so that it can also make a possible wobbling movement of the end in radial direction. Thus a long lifetime of the connecting point between the rotating end of the washing liquid pipe and the non-rotatable connecting piece is achieved.

Abstract: A sealed joint between two relatively movable surfaces. There is a recess in a first surface and a sealing member is received in with a close fit in the recess.
