A compressor includes a discharge conduit that extends between a discharge valve and a hermetic shell within the hermetic shell. A sealing connection assembly includes a housing mounted to one of the discharge valve and the hermetic shell. An inner surface of the housing has a tapered portion that contracts to a sealing edge. An end portion of the discharge conduit is positioned within the passage of the housing such that an outer surface of the discharge conduit is positioned on and contacts the inner surface of the housing at the sealing edge.

A pipe fitting configured to be coupled to a pipe, the pipe fitting including a body that is elongate along a central axis that extends in a longitudinal direction, the body including a shell, a stiffener, and a shell-stiffener. The shell includes a shell inner surface that defines a shell through hole that extends through the shell in the longitudinal direction. The stiffener is positioned within the shell through hole, and the stiffener includes a shell outer surface that faces the shell inner surface such that the stiffener outer surface and the shell inner surface cooperate to define a pocket configured to receive the pipe. The shell-stiffener seal member includes a first seal member and a second seal member aligned in a radial direction, which is perpendicular to the longitudinal direction.

A tube fitting for connection to a tube includes a main body structure and a tube liner. The main body structure is configured to receive an end of the tube and fluidly connect the tube to another component. The tube liner is positioned at least partially within the main body structure and is configured to extend into the tube. The main body structure and the tube liner are configured such that, when the tube is fully inserted into the tube fitting, the end of the tube is positioned at a predetermined depth within the tube fitting, and the main body structure and the tube liner cooperate together to provide an audible indication to indicate that the tube has been fully inserted into the tube fitting.

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.

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.

A tube coupling to receive and hold a tube includes a coupling body (10) having a throughway to receive a portion of a tube. A collet (17) in the coupling body has legs (21) with outer surfaces that engage with a tapered surface (24) in the coupling body which urges the legs inwardly to resist withdrawal of the tube. A biasing member (26) provides a biasing force without the tube inserted to urge the legs axially onto the tapered surface. The collet (17) can grip a large variety of pipe diameters. The coupling may be supplied with a number of inserts (30A-D) for sealing with the inner diameter of a pipe, the inserts having different diameters. A tool (50) for preparing the end of a pipe to receive the coupling is also contemplated.

A connector device for connecting to at least one component has a main body, a receiver and/or transmitter device arranged on the main body for receiving and/or transmitting signals and/or data, and a shielding device. The shielding device is arranged so as to be movable relative to the base body and has a shield for electromagnetic shielding of the receiver and/or transmitter device. The shielding device further includes a latch for latching the connector device with the component to be connected in a latching position, and a lock for securing the latch in the latching position. In the latching position, the receiver and/or transmitter device is not shielded by the shield.
