A rigid entry fitting configured to form a seal between a flexible pipe segment and a sump wall includes a fitting body having an inner surface defining a tapered opening, an insert received in the tapered opening, a shell received in an opening of the insert, a first pair of gaskets between an outer surface of the insert and the inner surface of the fitting body, a second pair of gaskets contacting an inner surface of the shell and opposite ends of the insert, and a nut configured to engage threads on an outer surface of the fitting body. When the nut is threaded onto the threads, the nut presses the shell and the insert into the tapered opening and presses the first pair of gaskets against the inner surface of the fitting body and the second pair of gaskets against the outer surface of the flexible pipe segment.

A push seal pipe adapter includes a grommet and a pipe adapter. The grommet fits inside the pipe adapter. The grommet includes a first adapter contact surface, a second adapter contact surface, and a third adapter contact surface. The pipe adapter includes a first grommet contact surface, a second grommet contact surface, and a third grommet contact surface. When the grommet is inserted into the pipe adapter, the first adapter contact surface of the grommet contacts the first grommet contact surface of the pipe adapter and the second adapter contact surface of the grommet contacts the second grommet contact surface of the pipe adapter. The push seal pipe adapter provides a pipe coupling end that receives a pipe. To couple, the pipe is pushed into the pipe coupling end.

A weldless thru wall fitting that provides a leak free connection to a vessel that can easily be installed and removed. The fitting also provides an integrated, removable, and repositionable dip tube to allow the liquid stored in the vessel to the drained via gravity to a level below the entry point of the fitting.

A method is shown for joining and sealing a female plastic pipe end having a belled end opening to a mating male plastic pipe end having an interior surface and an exterior surface. A sealing element is installed within a groove formed in the belled end of the female pipe section. The male pipe end is then inserted into the end opening of the female pipe end so that the elastomeric sealing gasket makes sealing contact with the exterior surface of the male pipe. A control mechanism located on the exterior surface of the male pipe end controls the distance the male pipe travels longitudinally within the end opening of the female plastic pipe to prevent overinsertion of the male pipe within the female pipe opening

An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.

Embodiments of an integrated piping conduit in accordance with aspects of the present invention include a push-to-connect fitting integrated with an adaptor device and associated methods that facilitate the re-use of push fittings without damage to the fitting elements or the pipe, while also facilitating connection to boxes such as electrical boxes in a manner that meets requirements and saves time for professionals dealing with the otherwise challenging management of multiple wires, cables and/or connections. Embodiments can incorporate an integrated release pusher and locking mechanism that allows for quick locking and unlocking of piping elements within a fitting. Embodiments can also include an adaptor having integrated head and body portions, and an ear member extending at least partially radially outwardly and at least partially axially outwardly from the outer surface of the body portion.

This disclosure pertains to a control device for the coolant flow in a cooling circuit of an internal combustion engine with the following characteristics: a housing with an inlet opening, an outlet opening and a movable control element for varying the flow-through cross section of the channel; an annular seal arrangement comprising a sealing frame and a sealing ring is seated between a sealing surface of the housing and a sealing surface of the control element. According to this disclosure, it is proposed that the sealing ring rests against a plane sealing surface of the housing in a sealing fashion and meets this plane sealing surface along a contact line that encloses a first surface area. Depending on the flow direction through the seal arrangement, the sealing ring features a surface section that has a defined circumference referred to the length of the contact line between the sealing ring and the housing. The sealing surface of the sealing frame is perpendicularly projected into a plane of projection and thereby has an inner and/or outer boundary line, which respectively encloses a second or third surface area that has a certain relation to the first surface area.
