A valve connector includes a housing and a pressing device. The housing includes an operative end, a coupling end, and a through-hole extending from the operative end through the coupling end. The pressing device includes a push seat received in the through-hole and located between the lever and the coupling end and a lever abutting against the push seat and pivotably connected to the housing. The push seat includes a first passageway. The lever includes a second passageway and is operable to move the push seat. When the lever is in a release position, the first passageway does not intercommunicate with the second passageway. When the lever moves from the release position to a locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

A compression-type fitting for quick connection of two hoses or hose sections and pipe and hose section in-line is adapted primarily for industrial, heavy duty hoses typically in one to three inches in diameter, although not so limited. A commercial application for which the connector has shown to be particularly useful is in the media blasting industry where hoses are subject to extreme conditions and break or leak after a relatively short period of use, requiring frequent shut down and repair or replacement of the hoses.

A fitting assembly includes a fitting comprising a housing and a connector assembly arranged within the housing. The connector assembly comprising a hollow interior and configured to be movable between an unactuated position and an actuated position. In the actuated position, the connector assembly is connectable to a pipe receivable within the hollow interior. An adapter coupled to the fitting includes a biasing mechanism configured to bias the connector assembly from the actuated position to the unactuated position.

A fluid coupling includes a body, a poppet valve assembly, a handle shaft assembly, and a retention member. The body has a fluid conduit, a through-hole extending through a sidewall, and one or more openings that extend between an external surface of the body and an interior of the through hole. The poppet valve assembly is disposed within the fluid conduit and is selectively movable between an open position and a closed position. The handle shaft assembly extends through the through-hole and into the fluid conduit and is interconnected with the poppet valve assembly such that the handle shaft assembly can be actuated to move the poppet valve assembly between the open position and the closed position. The retention member is insertable through the one or more openings and into the through-hole to interact with the handle shaft assembly to selectively hold the handle shaft assembly in the body.

A collar for connecting ducting components is provided. The collar includes a tubular wall having a line end and a free end, an annular flange extending radially outwardly from the line end, and a plurality of retaining tabs extending outwardly from the free end. A plurality of locking members are provided at the line end. The locking members are configured to releasably secure the flange to an adjacent member.

A nozzle adapter for connecting corrugated tubing to a fog nozzle housing. The nozzle adapter comprises a channel body and a clamp, the channel body having a connector section and defining a flow channel extending through the channel body. The connector section comprises an outlet opening of the flow channel and is adapted and configured to removably connect to a piece of corrugated tubing. The clamp is operatively connected to the channel body and operable to clamp a fog nozzle housing so that an outlet end of the fog nozzle housing faces downstream toward the flow channel.

Disclosed herein is a fluid connector system configured to couple a first fluid line structure, e.g. port, with a second fluid line structure, e.g. catheter. The connector system can include a connector body and one or more locking mechanisms designed to transition between an unlocked position and a locked position. The locking mechanism includes a first lever arm rotatably coupled to the connector body, and a second lever arm rotatably coupled to the first lever arm. The second lever arm can further be rotatably and releasably coupled to the port. Rotating the first lever arm uses mechanical advantage to urge the port to engage a catheter ensuring a tight seal therebetween even under high fluid pressures.
