There is disclosed breathing apparatus equipment which may be in the form of a waist mountable manifold. The breathing apparatus equipment comprises a manifold having a manifold inlet port for a source of breathable gas and at least one manifold outlet port for delivering breathable gas to a user. The equipment further comprises a strap arranged to be worn by the user, and a holder coupled to the strap and having a socket. The socket is configured such that the manifold can be removably located within the socket in multiple orientations.

A docking device for mechanically connecting an upper container module of a multipart container for a fluid and a lower container module of the multipart container. The docking device includes an upper docking segment, which is fastenable using an upper connecting means on opening of the upper container module, and a lower docking segment, which is fastenable using a lower connecting means on an opening of the lower container module so that fluid moves from the upper container module through a channel of the docking device into the lower container module, or moves due to buoyancy and/or due to pressure from the lower into the upper container module, if at least one valve body movable by means of an actuating assembly is in an open valve body position. An upper channel section is arranged in the upper docking segment and a lower channel section is arranged in the lower docking segment. The actuating assembly is actuatable so that it is movable from an open valve body position into a closed valve body position or from a closed valve body position into an open valve body position. The actuating assembly includes at least one blocking assembly comprising at least one blocking means that is moved into a blocking position during the docking process

A method and system for reducing leakage of hydraulic oil from a hydraulic outlet on a tractor, which involves removal of the female quick connect coupler from a legacy original equipment selective control valve and inserting into the void the following: a three part insert with a front stepped diameter segment, a back section, which is screwed into front stepped diameter segment, a sleeve which is configured to be inserted after a front O-ring is adjusted and a leading portion of a retention bolt.

A coupling manifold assembly has both regulated and unregulated flow orientations and includes a manifold body and a pressure regulator couplably received into the manifold body. The manifold body includes a pair of connection ports between which flow is movable through the manifold body, with the pressure regulator being received into a flow path between the connection ports. The pressure regulator is configured to regulate flow in a first direction between the connection ports and to allow for unregulated flow in an opposite second direction between the connection ports.

A waterproof quick coupler which closes a port of a pressure vessel in an air-tight state during a water leakage inspection of a welding portion of the pressure vessel of a compressor. The quick coupler comprises: an outer body having an opening formed at a distal end portion thereof, an inner body flexibly disposed to be rotatable and linearly movable in the outer body; a cap coupled to the distal end portion of the outer body, and a fixing lever flexibly disposed between the inner body and the cap to clamp and unclamp a port of a pressure vessel when the inner body moves forward and backward, wherein the inner body may be locked in the outer body when moving backward, and may be unlocked from the outer body when the outer body rotates in one direction.

A female coupling for a fluid quick connector and configured to be removably connected to a male coupling of the connector. The female coupling includes a valve assembly with a valve alternating between closed and open positions. The flow of a fluid from the female coupling towards the male coupling occurs in the open position. The female coupling includes a hollow body defining an inner cavity with a longitudinal axis for the flow of the fluid. The female valve assembly is housed in the inner cavity. The hollow body includes an end portion configured to be housed in a housing seat of an interface manifold. With the end portion in the housing seat, the tubular inner cavity is placed in fluid connection with at least one inner channel of the interface manifold. A constraint prevents rotation/translation of the end portion of the hollow body with respect to the housing seat.
