A fitting for connecting a branch conduit to a liner installed in a main pipe is configured to mechanically connect to the branch conduit as it is inserted into the branch conduit from inside the main pipe. The mechanical connection is established without rotating the fitting. The fitting can include a body having an outer shaft section for being received in the branch conduit and an inner flange section for opposing the liner within the main pipe. The fastener include one or more teeth that extend radially from the exterior of the shaft section. The teeth can be secured to the shaft section by deforming portions of the fitting body against the teeth. The flange section supports a gasket for sealing against the liner when the fitting is installed. The flange section can include a rim that maintains the gasket in the proper position.

A collar for use on a water filtration tank adapter. The collar is formed as a ring adapted to thread onto the tank connection end of the adapter and abut the nut portion between the tank connection end and the pipe end of adapter. An o-ring, square in cross-section, is disposed on a top surface of the collar, offset medially towards the center. This top o-ring is adapted to abut the nut portion of the adapter. Another o-ring, square in cross-section, is disposed on the bottom surface, offset medially away from the center. This bottom o-ring is adapted to abut the tank head upon use. Accordingly, a water-tight seal is formed at the tank connection end and tank head, the collar functioning as both a positive stop and as a substitute for pipe tape.

Apparatus and method of forming connector brackets for irrigation laterals along a prefabricated lay-flat pipe and lay-flat pipe with such connector's brackets, wherein an opening is formed at one wall of the premanufactured pipe, a separation means is positioned inside the pipe opposite the opening while separating the one wall from the second wall of the pipe, and an injunction molding is performed into a mold cavity, in order to form the bracket affixed to the one wall of the prefabricated pipe and around the opening.

The invention relates to a screw element comprising an internal torque limitation for fastening a line, in particular a liquid-conducting line, to a counter-piece, in particular to a device connector or to a coupling for a further line, said screw element having a connection part, which preferably has a thread, and an actuation part; and having a torque limiting unit that limits a torque that can be transmitted from the actuation part to the connection part, wherein the torque limiting unit is arranged between the connection part and the actuation part and has a limiting element, in particular a separate limiting element, that can be assembled from at least two limiting element parts connectable to one another and that limits the torque limiting unit in an axial direction of a longitudinal axis of the screw element. The invention further relates to a system comprising at least one screw element and a line fastened to the screw element.

An adjustable length pipe connector having an axially extending and hollow pipe body with internal threads provided therein. The pipe body includes external threads provided on outer portion thereof for coupling the connector to a pipe connection. Further, the pipe body includes a washer provided within the pipe body. The washer is adapted to be moved axially within the interior portion. Also, a first and a second length adjustor peg is provided within the pipe body. The first and the second length adjustor pegs can be moved and positioned adjacent to the washer so as to achieve a desirable length of the adjustable length connector. Upon achieving the desirable length, the washer is juxtaposed relative to the first peg and an excess portion of the pipe body adjacent the second end is removed. The washer may be cylindrical. The washer may have a wire mesh to block impurities.

A screw-connection system for connecting a long-shaped part with a terminal geometry includes at least a pressure element, a terminal part, and a seal. The pressure element has at least one contact-wall section with a contact surface. The seal has at least one outer radial-seal surface and at least one axial-seal surface. The outer radial-seal surface of the seal interacts in a sealing manner at least partially with the contact surface of the contact-wall section and the axial-seal surface is configured at least for partial sealing with the terminal geometry.

The present technology generally relates to devices, systems and methods for providing robust sealing between surfaces in a pressurized system, such as a chromatography system. In particular, the devices, systems and methods relate to compliant and resilient parts that can be reused and/or reinstalled while providing a pressure tight sealing surface even within a high pressure environment (e.g., 1000 psi or greater).
