摘要： A fitting for a pipe has a cylindrical sleeve and a spigot fitted concentrically within the sleeve. The sleeve is slidable along the spigot in a proximal direction. The sleeve has a gripper ring cavity with a conical bearing surface with a diameter that is smaller at the distal end and a larger at the proximal end. One or more gripper rings fit within the cavity and slidingly engage the bearing surface. The spigot has an outer surface sized to fit within a proximal end of the pipe. The inner surface of the gripper rings and the outer surface of the spigot define an annular space with a first radial width sized to accept insertion of the proximal end of the pipe. When the sleeve is moved with respect to the spigot in the proximal direction toward a sealed position, the rings are inwardly compressed by the bearing surface to grip an outer surface of the pipe. The end of the pipe is drawn into a space between the sleeve and the spigot with radial width smaller than the first radial width.

摘要： A pipe system has a pipe with an axis and a retainer groove formed in an exterior of the pipe near an axial end of the pipe. The pipe system also has a tubular body with an interior and one end sized to receive the axial end of the pipe therein to form a pipe assembly. The pipe system also has a retainer configured to be received in the retainer groove and to be both axially movable and radially movable relative to the retainer groove during formation of the pipe assembly and to retain the pipe and the tubular body in the pipe assembly.

摘要： Improvements to stab-type pipe fittings capable of being inserted onto plastic pipes and provide a leak proof connection are provided. The pipe fittings have an outer casing with pipe ports, a hollow inner casing positioned within the outer casing, a pipe gripper and stiffener positioned within the inner casing. The pipe ports have an elongated lip that straightens a pipe inserted into the fitting. The stiffener provides a multi-compression seal to facilitate the leak proof connection.

摘要： A push-to-connect coupling with integrated filtration is disclosed. In one aspect, the coupling comprises a tube support, a collet and a filter element. The coupling may include a seal. The coupling connects to a cavity, which may be a portable fitting. The cavity may be a connection on a separate device or system, such as an air tank or other devices. The filter element may be dome-shaped. The tube support is easily assembled with the cavity, for example by threading, to capture the filter element. The tube is connected to the coupling by pushing the tube over the tube support and through the collet. The collet interacts with a reduced diameter section of the cavity to apply a clamping force from the collet on the tube and secure the tube in place. The tube is easily removed from the cavity simply by pushing the collet farther into the cavity to remove the clamping force on the tube, and then pulling the tube out.

摘要： A connection socket for a tubular connection includes a socket cup having a metal alloy composition and a sealing portion. A primary seal is positioned within the sealing portion. The primary seal includes an elastomeric material having a service temperature. One or more spacer rings are positioned within the sealing portion. A secondary seal is positioned within the sealing portion. The secondary seal includes a metal composition, wherein the secondary seal has a melting temperature at or above the service temperature of the primary seal. One or more locking rings are positioned within the sealing portion, wherein each of the one or more locking rings comprises a biting feature defined along an internal circumference of the locking ring.

摘要： A push to connect fitting assembly includes first and second fitting components joined to define an interior cavity, a seal device, a retainer, and a biasing member. The seal device is disposed in the interior cavity, and forms a seal between one of the first and second fitting components and an outer surface of a conduit end when the conduit end is inserted into the outboard end of the first fitting component. The retainer is assembled with at least one of the first and second fitting components, and includes a gripping portion that grips the inserted conduit end. The biasing member is axially disposed between the retainer and the seal device, the biasing member applying a first axial load to the retainer to produce a gripping force between the gripping portion and the inserted conduit end.

摘要： A push to connect fitting includes a body member adapted to receive a conduit end, a conduit comprising a first end that can be axially inserted into the body member and a conduit gripping device attached to an exterior surface of the conduit, and a retainer that retains the conduit in place when said conduit is fully inserted into the body member. Additional embodiments include providing a seal with the fitting that seals the exterior surface of the conduit, an optional load retaining sleeve for the conduit gripping device, and an optional gimbal. The push to connect aspect may be realized in the form of a single action unthreaded mechanical connection.

摘要： The present invention relates to a pipe coupler having a function of covering a pipe. More particularly, the present invention relates to a pipe coupler which can prevent a coating layer of a pipe coated with the coating layer from being peeled from a tip of the pipe by a continuously acting hydraulic pressure by forming a pipe locking protrusion in which a front end of the pipe is surrounded and covered with a packing member, seal even a pipe having a non-smooth or grooved outer peripheral surface, and furthermore ensure watertightness or airtightness more reliably by using a pair of packing members acting in the form of a swash cam plate in accordance with an insertion of a pipe.

摘要： A tube connector for attachment to an end of a tube of a pressurized fluid system has a housing, a main sealing element, a gripping element and a cone element. The main sealing element is arranged for sealing an inner surface of the housing to an outer surface of a tube. The gripping element comprises a gripping edge for engaging with an outer surface of a tube. The cone element limits a movement of the grip-ping element. The tube connector further has an integrated release element. The release element has a tubular part, a top part and an environmental sealing. A release edge of the tubular part engages with the gripping element and the environmental sealing is adapted for sealing a receptacle formed in the housing of the environment.
