A multiport pump and adapter kit for use with a water circulation system for a body of water includes a centrifugal pump assembly having a plurality of outlet ports oriented in different directions and at least one adapter having a first open end configured and dimensioned to be removably connectable to one of said outlet ports, a second open end configured and dimensioned to be removably connectable to a water circulation system, and a hollow body connecting the first open end and the second open end.

An improved hose assembly for a marine vessel bulkhead comprises a hose having a first end with a first hose fitting and a second end with a second hose fitting. There is a base plate having an opening which receives the hose. The base plate is positioned on the hose between the first hose fitting and the second hose fitting. There is a bend restrictor releasably coupled to the base plate. The bend restrictor has coils which wrap around the hose. The base plate clamps onto the bend restrictor and the bend restrictor clamps onto the hose, thereby restricting relative axial and rotational movement of the hose.

A quick-access hinged lid assembly for flanged riser, having two-part clamp, having an inner face shaped to conform to the surface flanged riser, first clamp ring and second clamp ring are connected by a clamp hinge, a lid having an exterior surface and an interior sealing surface to abut the flanged riser exterior surface, wherein the interior sealing surface includes annular groove, gasket or o-ring positioned therein groove to seal flanged riser exterior surface and interior sealing surface, a lid hinge configured between clamp and lid, lid hinge having a swing bolt slot and pin bolt to provide adjustment of the lid to enable the lid to mate flat with flanged riser, swing bolts positioned on the perimeter and pivotable from the clamp ring with hand operable fasteners to press gasket between interior sealing surface of the lid and flanged riser exterior surface in a closed position.

A pipe joint includes a first member, a second member, a weld experiencing transverse contraction and joining a first outer cylindrical end portion and a second outer cylindrical end portion butted with their end faces meeting over the entire circumference, an annular sealed area produced by the transverse contraction of the weld causing a first pressing portion and a second pressing portion to be displaced toward each other, a heat transmission suppressing member arranged in a space delimited by a weld forming area and a to-be-sealed area, inside the first and second members assembled, to suppress transmission of heat applied in welding from the weld forming area to a to-be-sealed area, and a first stop ring fitted in an outer cylindrical surface of the heat transmission suppressing member to hold the heat transmission suppressing member against an inner surface of the first or the second member.

An anti-debris device releasably engages and covers an unconnected end of a fluid-conveying quick disconnect connector to prevent debris intrusion. The device comprises a boot defining a cavity shaped to receive the connector, a connector-receiving access opening to the cavity, and a closure member such as flexible sheet slit to form resilient fingers movable between an opening-covering position preventing intrusion of foreign matter when the boot is not being used, but that flex to a connector-receiving position when an unconnected portion of a connector is biased against the closure member. The fingers assist in retaining the device on the connector. Various embodiments allow retaining the anti-debris device to a particular connector when the device is not in use, and/or for storing/protecting multiple connectors. Related methods are also disclosed and discussed.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

A system and method for providing a bi-directional, valve-less sampling port for use with gas sampling bags, wherein the valve-less sampling port has few parts and no moving parts, the sampling port is coupled to a gas sampling bag using a base component that has a portion inside and outside of the gas sampling bag, a cap that is disposed over the base to make an interference fit, an O-ring between the base and the cap that applies a sealing force to hold the gas sampling bag against the base, and a dome seal inside the base and held in place by the cap, wherein the dome seal functions as a one-way check valve to prevent flow out of the gas sampling bag until a sampling adapter is inserted through the cap and the dome seal to provide access to the gas sampling bag for extraction of gas.
