The invention includes a connector for coupling to a composite pipe, and methods for forming the same. The connector has a seal carrier forming a fluid passage that is made of a first material and that includes a seal receiving portion configured to receive at least one seal and a first coupling surface on an outer seal carrier surface. The connector also has an interconnect with a passage configured to receive the seal carrier that is made of a second material and includes a second coupling surface on an inner interconnect surface configured for coupling with the first coupling surface to connect the seal carrier and the interconnect and a third coupling surface on an outer interconnect surface.

A pressure differential device for attachment to a vessel to be used to smoke or vaporize tobacco or other consumables substances meant to be inhaled for pulmonary applications. The pressure differential device includes a chamber for receiving consumables, a tunnel running through the device, a flange for proper seating in a vessel, and a inner protruding member for attaching tunnel extension such as a straw.

A press fitting device, components and method provide one or more indicators to provide a visual indication that the fitting has been properly pressed around a tube and that the correct amount of pressure has been provided to create a permanent seal. In embodiments, a sealing ring is retained within an indentation of a main body component of the fitting and the sealing ring is expandable upon compression to be visible through an opening in the main body component.

Fluid connector assembly and methods usable to establish a sealed fluid connection. The connector assembly comprises a female union connector having an axial bore extending therethrough, internal threads, and an internal shoulder. The connector assembly also comprises two male connectors, each male connector having an axial bore extending therethrough and external threads. The connector assembly further comprises two ring-shaped seals adapted to form a fluid seal between the female union and the male connectors. The first seal contacts the first side of the internal shoulder and a front end of the first male connector to form a fluid seal therebetween. The second seal contacts the second side of the internal shoulder and a front end of the second male connector to form a second fluid seal therebetween.

Disclosed herein is a bladder that may be configured as a supply bladder and as a discharge bladder in a fluid coupler. The bladder may comprise at least one overtube having a lumen in which is positioned a catheter, which may include a fluid passage portion and an inflation portion, wherein the overtube has a first securing edge and a second securing edge, at least one gland nut to be secured to the first securing edge of the overtube, the gland unit may be tightened internally to the first securing edge of the overtube, a cord grip located with the gland unit when the gland nut is secured to the first secured edge, at least one sealing coupler ring to be secured to the second securing edge of the overtube, at least one bladder insert for creating a seal between the overtube and the sealing coupler ring within the catheter, and a plurality of O-rings to be secured inside the sealing coupler ring with a screw unit.

A coupling assembly for releasably interconnecting fluid passages comprises male and female coupling members, which are mated by inserting a probe and socket of the members respectively. Each coupling member has a first end arranged for connection to a fluid passage. When mated in use, the coupling assembly provides a straight fluid conduit between the fluid passages comprising through-bores in each of the coupling members coincident along a first longitudinal axis. When mated in use, the probe and socket are arranged coincident on a second longitudinal axis, which is inclined to the first axis. Sealing means comprising an annular sealing ring proximate each of the socket and probe are arranged, when mated in use, either side of an intersection between the through-bore and socket. The sealing arrangement is such that fluid within the fluid conduit exerts a net force resisting separation of said coupling members.
