Abstract: The present application is directed to a closure for a container having a generally annular neck defining a container opening having a central axis, the closure including: an annular top wall having opposed inner and outer surfaces; a generally annular skirt extending downwardly from the inner surface of the top wall, the generally annular skirt having opposed outer and inner surfaces; and an elastic annular seal member extending downwardly from an inner surface of the top wall, the annular seal member adapted to engage the inner surface of the neck of the container.

Abstract: A poppet including a single-piece, unitary body defining a plurality of discrete sealing surfaces and a mechanical attachment configured to engage the body with a piston of a valve assembly.

Abstract: A dual containment fitting may include a primary tubing, a secondary tubing, and a dual containment body. The secondary tubing may surround and be concentric with a first portion of the primary tubing forming a first leak containment space between the primary tubing and the secondary tubing. The dual containment body may include a flare fitting portion and a primary containment nut portion. The flare fitting portion may surround and be concentric with the primary tubing forming a second leak containment space between the primary tubing and the flare fitting portion. The primary containment nut portion may surround and be concentric with the flared end of the primary tubing forming a third leak containment space between the primary tubing and the primary containment nut portion. The primary containment nut portion may include at least one leak passage hole connecting the third leak containment space with the second leak containment space.

Abstract: A fluid transport coupling subcomponent can include a body having a first axial end with a first axial face, a second axial end, and a hollow conduit extending between the first and second axial ends, a tongue extending longitudinally from the first axial face; and a groove recessed into the first axial face. The tongue can extend a distance, DT1, from the first axial face and the groove can extend a distance, DG1, into the body from the planar face, where DG1 and DT1 can be different.

Abstract: A leak detection system including a sensor having a first state having a first condition when dry and a second condition when wet, and a second state adapted to monitor the operability of the sensor; a communication device operatively connected to the sensor; and an attachment element adapted to attach the leak detection system to a fluid component for monitoring fluid leakage.

Abstract: A spring for use in a check valve is formed from a single piece of a polymeric material and includes a proximal end, a distal end, and a body positioned between the proximal end and the distal end. The body includes a wall, a proximal opening on the wall and a distal opening on the wall, and a bellows between the proximal opening and the distal opening. Further included is a process of forming the spring.

Abstract: A plumbing assembly includes a plumbing fitting having a body. The body includes a main body portion having a main bore extending there through. A peripheral body portion extends from the main body portion. The peripheral body portion includes a distal end and a sampling bore extends through the peripheral body such that the sampling bore is in fluid communication with the main bore. The plumbing assembly further includes a sampling valve threadably coupled to the distal end of the peripheral body portion of the plumbing fitting. The sampling valve extends at least partially into the sampling bore without extending into the main bore. As such, the main bore is unimpeded by the sampling valve and use of the sampling valve imparts substantially no pressure drop in a fluid passing through the main bore of the plumbing fitting.

Abstract: A diaphragm valve is provided which can be used both with corrosive liquids without valve component degradation and with chemically pure liquids without deleteriously affecting the liquids' purity. The valve incorporates a valve body having at least one inlet and at least one outlet, with a valve seat between each inlet and outlet. A pair of spaced-apart diaphragms are provided which are in contact with the fluid flowing through the valve. A poppet assembly, which extends between the diaphragms, incorporates a valve stem with a valve plug on one or both ends which engages an associated valve seat. A leak detection port is provided to detect liquids which may leak through either one of the two diaphragms.
