A backflow prevention assembly is configurable with varying lay-lengths and orientations. The assembly includes coupling assemblies and valve bodies that adjust in length and/or rotation to allow for the varying lay-lengths and orientations of the backflow prevention valves and assemblies with and without certification. A coupling assembly is connected to a backflow prevention valve and includes an outer sleeve and an inner sleeve that is slidingly received within the outer sleeve. The lay-length is adjusted by slidably moving the inner and outer sleeves with respect to one another.

Provided is a linear movable rotary union including a driving shaft comprising a plurality of fluid supply paths; a hollow middle housing surrounding an outside of the driving shaft and comprising a plurality of first through holes in a sidewall; a plurality of first sealing members provided between the middle housing and the driving shaft to prevent leakage of a fluid; a hollow outer housing surrounding an outside of the middle housing and comprising a plurality of second through holes in a sidewall; and a plurality of second sealing members provided between the middle housing and the outer housing to prevent leakage of the fluid, and wherein the driving shaft is installed to be capable of rotational motion in the middle housing, and the middle housing is installed to be capable of reciprocating motion in an axial direction in the outer housing.

A fluid transfer conduit comprising: an electrically conductive tube of fibre reinforced polymer composite material which has an electrically conductive outer surface and an electrically conductive inner surface; and on at least one axial end of said conduit, a non-electrically-conductive band formed on either the outer surface or the inner surface of the electrically conductive tube. Forming a non-electrically conductive band on the end of the conduit electrically isolates the electrically conductive outer surface of the conduit from the electrically conductive metal socket into which it is to be inserted.

A dynamic sleeve seal fitting may comprise a first sleeve having a tongue portion, a second sleeve having a groove configured to receive the tongue portion, and a first seal member coupled to at least one of the tongue portion or the groove and configured to generate a seal between the first sleeve and the second sleeve in response to inserting the tongue portion into the groove.

A quick connect fluid connector is directly connected to a fluid port of a fluid manifold using a quick connect fluid connector swivel that is configured to permit rotational and/or longitudinal movement of the quick connect fluid connector relative to the fluid port. The relative axial and/or rotational movements provided by the swivel eliminates the need for a fluid hose to be used in the fluid path between the quick connect fluid connector and the fluid port.

Various systems and assemblies that can be utilized with hydraulic and other fluid flow lines are disclosed. According to one embodiment, the present application discloses an assembly that can include a first section, a second section and a third section. The first section can define a first passageway therein to receive and allow for passage of a fluid. The second section can define a second passageway that communicates with the first passageway. The second section and the first section together can form a first ball joint having an internal portion and an external portion. The first ball joint can comprise a moveable coupling between second section and the first section. The third section can define a third passageway that communicates with the second passageway. The third section can telescopically receive the second section therein and can be configured to form a linearly moveable joint between the third section and the second section.

A telescopic fitment for connection of a magnetic filter into a central heating system circuit includes a first connector and a second connector, each of the first and second connectors including a filter connection end for connecting with the magnetic filter and a circuit connection end for connecting with the central heating system circuit, at least one of the first and second connectors including an inner pipe and an outer pipe, the filter connection end being provided on one of the inner or outer pipes and the circuit connection end being provided on the other of the inner or outer pipes, the inner pipe being slideable within the outer pipe for adjusting the position of the circuit connection end with respect to the filter connection end, whilst maintaining a sealed fluid path between the circuit connection end and the filter connection end.

A first projection is formed on the outer periphery of a bulb part, a second projection is formed on the socket rear end of the bulb part, a tapered part is formed with a decreasing diameter from the inner periphery of a heel part to the inner periphery of the second projection, and a third projection is formed on the tapered part. A first dimension B from the first projection to the third projection in an inclination direction opposite to an inclination direction G of the tapered part is smaller than a second dimension C from the first projection to the second projection in a radial direction A.

The invention relates generally to a system used to produce a prototype part and subsequently an accurate design specification for a fluid or gas handling system/hose and or tube assembly, followed by the subsequent communication of that specification into an ordering interface that processes the specification into a usable format as a means to accurately produce and re-create the original specification in a remote location by a specific manufacturing process, in order to supply the originator of the design an accurate, working part, produced in the specified materials in a rapid, convenient and cost effective manner. The process has global applications in various industries, markets and vehicle or machinery types, particularly where it is inconvenient or prohibitively expensive to have the work performed on-site by a technician.

An adjustable pipe and methods for manufacturing and installing the same may include at least two pipes, a seal structure and a base coupling. The adjustable pipe may be for fluid connection between a first object and a second object. The at least two pipes may include a first pipe and a second pipe that is configured to be received by at least a portion of the first pipe. The adjustable pipe may also include a first inner collar proximate the first end of the first pipe and a second outer collar proximate the second end of the second pipe. The seal structure may be provided between the first pipe and the second pipe and between the first end of the first pipe and the second outer collar proximate the second end of the second pipe.
