Abstract: One variation may include a telescoping pipe comprising: a first pipe and a second pipe, wherein the second pipe is constructed and arranged to stretch and retract along the first pipe so that a length of the telescoping pipe can be extended or shortened; a first O-ring coupled between the first pipe and the second pipe; and a second O-ring coupled to an inner surface of the second pipe.

Abstract: One variation may include a telescoping pipe which may be retracted or stretched.

Abstract: An injection molded piston formed integrally of polymer material includes a body extending along an axis and providing a mounting surface, first and second partial cylindrical surfaces located above the mounting surface and formed with a concave recesses, a first shoe located above the mounting surface and radially outboard of the cylindrical surfaces, and a second shoe located above the mounting surface and radially outboard of the cylindrical surfaces.

Abstract: A clampless coupling which attaches a hose to a nipple without need of a clamp at the end of the hose to ensure sealing, including a connector and a nipple of a fluid system component. The connector is sealingly pre-connected at one end with a hose; the opposite end is in the form of a sleeve. The sleeve features a notch at its forward end, a boss on a resilient lock arm, and an O-ring seal. The nipple has a pocket depressionally formed on its outside nipple surface and an alignment tab. In operation, a user slides the sleeve over the nipple by pressing the connector toward the near end of the nipple. As the sleeve slides over the nipple, the tab is received by the notch to align the connector with the nipple, the boss drops abuttably into the pocket, and the O-ring seal sealingly compresses between the nipple and the connector. A seal assurance feature reveals improper connection when a pressure test is undertaken.

Abstract: An assembly and method for installing a snap-fit electrical connector, wherein the assembly includes a base; at least one pair of flange members supported by the base for locating a tether, cable or other electrical wiring; at least one pair of resilient members supported by the flanges forming the pair of flange members for engaging a mating recess or opening; and at least one pair of second flange members supported by the base for providing a snap-fit connection with a second mating recess or opening. The snap-fit connector assembly also includes an electrical connector portion supported by the base for providing a location for establishing an electrical connection.
