A coupler for connecting a first fluid conveying member and a second fluid conveying member includes a first coupler half, a second coupler half, and a conductive gasket. In embodiments, at least one of the first coupler half and the second coupler half include an annular groove configured to receive at least a portion of the conductive gasket; the conductive gasket comprises non-metallic material, the first coupler half and the second coupler half are configured to connect and circumferentially surround portions of said first and second fluid conveying members, and the conductive gasket provides a portion of a conductivity path from a first end of the coupler to a second end of the coupler, and may be part of a conductivity path from a first fluid conveying member to a second fluid conveying member. Embodiments of a non-metallic conductive gasket and methods of making a coupler assembly are also disclosed.

Systems and methods for a segmented aircraft refueling tube with a tube interface include a plurality of seals configured to deform while allowing relative movement between tube segments. The systems include a tube interface that includes a first ring, a second ring, a first seal disposed between a first ferrule and the first ring, a second seal disposed between a second ferrule and the second ring, a third seal disposed between the first ring and a sleeve, and a fourth seal disposed between the second ring and the sleeve. The plurality of seals per ring allow for misalignment between the ferrules to be accommodated by two or more seals.

A release agent spray system for a vehicle that is used for removing temporary tape from pavement surfaces. The release agent spray system includes a reservoir containing a release agent, a pump for pumping release agent from the reservoir, and a handheld sprayer connected to the reservoir by a fluid conduit or tube and connected electrically to the pump. The handheld sprayer includes an activation switch for activating the pump to deliver release agent from the reservoir to the handheld sprayer.

A pipe segment having an insulated electrical conductor includes a first electrical contact disposed at one end of an electrical conductor on an interior of the pipe segment from a male threaded connection on one end to a female threaded connection on the other end of the pipe segment. A second electrical contact is on the other end of the insulated electrical conductor. The first contact makes electrical connection with the second contact in an adjacent segment when the male connection on one segment is engaged to the female connection on the adjacent segment. A seal disposed on an interior of an insulating layer on an interior wall of each respective pipe segment provides a space beyond the end of the seal to enable inward flexure of the seal under pressure such that lubricant extruded by connecting the male threaded end and the female threaded end is pressure relieved.

An isolator includes a first fluid-carrying member and a second fluid-carrying member; and a resistive, semi-conductive or non-conductive component located between the first and the second fluid-carrying member. The component conveys fluid flowing from the first fluid-carrying member to the second fluid-carrying member. The isolator further has a reinforcing composite encircling the first fluid-carrying member, the second fluid-carrying member and the component. The reinforcing composite having first fibers extending at an angle of between −30 degrees and +30 degrees to a longitudinal axis (A-A) of the resistive, semi-conductive or non-conductive component; second fibers interwoven with the first fibers and extending around the first fluid-carrying member, the second fluid-carrying member and the component at an angle of between +60 degrees and +90 degrees and/or between −60 degrees and −90 degrees to the longitudinal axis (A-A); and a resin.
