An electrostatic discharge tubing segment includes a porous non-conductive interior surface and an adjacent conductive polymer portion. The conductive polymer portion is configured to transfer electrostatic charge generated by a charged fluid passing through the tubing segment to ground such that electrostatic discharge can be mitigated.

Electrostatic discharge mitigation tubing

A flow path for a fluid from a fluid supply which may include a plurality of operative components including a body portion and a plurality of tubing connector fittings. The operative components may be connected by a plurality of tubing segments. Each body portion may include a nonconductive fluoropolymer portion and an outer conductor that extends between each of the plurality of tubing connector fittings and that is unitary with the non-conductive fluoropolymer portion. The plurality of tubing segments may include a non-conductive fluoropolymer tubing portion and an axial strip of conductive polymer. The outer conductor of each body portion conductively connected with tubing segments connected thereto. Each of the connectors may include a bridging component for conductively connecting the respective outer conductor of the body portion to the strip of conductive polymer of the connecting tubing segments.

Fluid circuit with integrated electrostatic discharge mitigation

This disclosure provides operative components that mitigate electrostatic charge in fluid circuits. Illustrative embodiments include diaphragm valves that provide fluid control and allow static charge to dissipate when these diaphragm valves are grounded.

Electrostatic discharge mitigation valve

Welded check valves include a poppet assembly, a spring, and a disc that contacts the spring. The disc may be held at a position away from a weld when forming the welded check valve. Embodiments may include retention features configured to allow one or more of the poppet assembly and disc to pass the retention features in an assembly orientation, and to retain those elements when they are in an operational orientation. Methods include inserting the poppet assembly, contacting the poppet assembly with a spring, inserting a disc, retaining the disc away from a weld side, and welding the check valve together. The poppet assembly and/or disc may pass one or more retaining features when inserted, and be retained by the retaining features when the check valve is operated. The weld may be a thermal weld.

This disclosure relates generally to a containment system for containing a fluid. More specifically, the disclosure relates to a fitment for attaching a liner within a container and providing a fluid path from the liner to an outside of the containment system. The liner and at least a part of the fitment provide the wetted surfaces for the containment system, while the fitment has a portion that can be joined to an outer container that, for example, provides rigidity and light protection. The fitment may be a two-piece fitment with a liner fitment to which the liner may be joined, and a retainer that may be joined to a container, where the liner fitment and the retainer are joined to one another, for example by a mechanical connection. The liner and liner fitment may be fluoropolymers or other non-reactive polymers. The container and retainer may be UV-blocking polymers.

A fluid circuit () defining a flow path for a fluid from a fluid supply () toward a process stage (). The fluid circuit may include a plurality of operative components () including a body portion () and a plurality of tubing connector fittings (). The operative components may be connected by a plurality of tubing segments (). Each body portion may include a non-conductive fluoropolymer portion and an outer conductor () that extends between each of the plurality of tubing connector fittings and that is unitary with the non-conductive fluoropolymer portion. The plurality of tubing segments may include a non-conductive fluoropolymer tubing portion () and an axial strip () of conductive polymer. The outer conductor of each body portion conductively connected with tubing segments connected thereto. Each of the connectors may include a bridging component () for conductively connecting the respective outer conductor of the body portion to the strip of conductive polymer of the connecting tubing segments.

A fluid circuit includes a plurality of tubing segments and a plurality of operative components. Each tubing segment includes i) a non-conductive polymer portion defining a fluid passageway and ii) one or more interior conductive fluoropolymer stripes extending axially to the ends of each of the respective tubing segments. Each operative component includes a conductive fluoropolymer that extends between a plurality of tubing connector fittings forming a part of the fluid circuit, wherein each of the tubing connector fittings conductively connect the respective conductor of the operative component to the interior conductive fluoropolymer stripes of the tubing segment to provide a path to ground that extends through each operative component and each tubing segment.

This application provides a valve member that includes a diaphragm portion and a valve head attachable to the diaphragm portion. The valve head includes an engagement portion configured to engage with a valve seat defined in the valve. The engagement portion is formed of a melt processable material that contains at least one fluoropolymer. The diaphragm portion is formed of a material that is non-melt processable and contains at least one fluoropolymer. This application also provides a valve that includes the valve member and a passageway with the valve seat. The valve head is configured to be moveable relative to the valve seat.

An anti-rotation device for preventing a hydraulic connector assembly from leaking. Various embodiments of the anti-rotation device provide a mechanism whereby threadably engaged connectors, such as compression fittings, are permitted to rotate only a fraction of a turn after loosening. For many applications, the limited degree of loosening is sufficient to prevent the onset of leaking. Structurally, the anti-rotation device can include a band that is secured to a female nut of a hydraulic connector. Protrusions extend laterally from the band and engage with a stop tab on the male body of the hydraulic connector assembly, thereby limiting rotation of the female nut that would otherwise cause leaks. Locking provided by zip tie structures proximate the free ends of the anti-rotation device.

Anti-rotation device for hydraulic connectors

A high torque polymer fittings useful in fluid handling systems. The fittings are especially useful for fluid handling fittings having diameters of one inch or greater. Various embodiments of the fittings disclosed accommodate specialized wrenches for securing the fittings, the wrenches being used to tighten the fittings to a desired torque.

A connection verification tool for verifying a secure connection between two fluid handling components of a fluid handling system. A connection verification tool can include a gauge portion sized sized to be placed over a first fluid handling component connected to a second fluid handling component to verify a secure connection between the two components. If the first fluid handling component is not securely connected to the second fluid handling component such that additional torque may be required to complete the connection between the two components, the gauge portion of the connection verification tool will not fit over the first component coupled to the second component.
