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 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.

The inventive system and method advantageously enable superior preserved storage and selective dispensation of liquids by storing wine (or other liquids) in a pressurized environment to ensure that the stored liquid does not come into contact with air, and then by selectively dispensing a portion of the stored liquid, in accordance with a desired dispensing regime, by utilizing a controlled source of pressure force to apply a sufficient pressure to the pressurized environment to expel the desired volume of the liquid in a pressurized stream directed to a dispensing/pouring interface through a conduit or equivalent delivery system. In at least several novel embodiments thereof, the system and method of the present invention are configured for use with wine-in-bag (WinB) products.

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.

A quick-fit connector (1) for the connection of a pipe of a pneumatic system comprises a main body (2) and a pincer body (40). The main body (2) comprises a side wall (30) slidingly insertable in a base portion (58) of the pincer body (40) to prevent the entrance of dust, splinters and similar in the interspace between the pincer body (40) and main body (2).

A bathroom quick coupling includes a main body and a positioning clamp. One end of the main body is recessed to form a hollow room and an opening. The hollow room has a thin section and an expanded section. An inner diameter of the expanded section is greater than an inner diameter of the thin section. The expanded section is connected to a side of the thin section distant from the opening. The positioning clamp is in the hollow room and has a base in ring shaped. A plurality of clamping blocks is extending from one side of the base. The clamping blocks surround the base and are arranged spacedly with each other for engaging with and positioned with the external pipe. Each of the clamping blocks is slightly deformable within a gap between adjacent clamping blocks, and the clamping blocks are correspondingly extending to the expanded section.

A push-in tube connector port for connecting a tube to a pressurized fluid system is provided. The push-in port includes a central recess for receiving the tube, a sealing arrangement inside of the recess, a locking ring engaged within the recess, and a tube gripping ring having an inwardly directed gripping edge. The locking ring has a U-shaped cross-section. A number of circumferentially distributed slots subdivides an outer ring wall of the locking ring into a number of outer ring wall portions configured to be elastically deflected towards the center by the flange of an insertion end opening, when the annular double ring component is pressed into the recess, and to elastically flex back outwardly once the outer ring wall portions have passed the flange such that an upper edge of each of the outer ring wall portions engages an inner surface of the flange to secure the locking ring in the recess.

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 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.
