A dielectric tubular fitting for dissipating electrical energy, while providing fluid flow therethrough, the fitting including a non-metallic reinforced hose extending between and fluidly interconnecting spaced metallic tubes, and a means within the hose for providing controlled electrical resistance to dissipate positive charge of fluid flowing through the fitting. A dielectric cover is provided surrounding and encapsulating the hose, and at least partially encapsulating each of the tubes.

Dielectric fitting

A fluid coupling for providing a fluid connection between an electronic module and a rack having an electrical connector to which the electronic module is connected, comprises a male coupler and a mating female coupler. The male coupler includes a male coupler body and a nipple, and the female coupler includes a female coupler body and a socket for receiving the nipple to establish a sealed fluid flow path between the male and female couplers when the couplers are connected together. At least one of the nipple and socket is mounted in the respective coupler body for limited transverse movement relative to the respective coupler body, and at least one of the couplers includes an axially extending spud that will initially telescopically engage the other coupler to initially coaxially align the male and female couplers within a first tolerance range and then to telescopically engage an alignment surface on the coupler body of the other coupler to coaxially align the male and female coupler bodies within a second tolerance smaller than the first tolerance.

Dual purpose alignment and fluid coupling

In an improved quick disconnect coupling comprised of operator-actuated coupler and nipple assemblies, the former including an actuating sleeve, with the coupled assemblies having first and second sealing assemblies respectively, wherein the improvement comprises, in combination, that each of the sealing assemblies includes, in addition to the known torodial sealing element, a first non-continuous metallic backup ring and a second non-metallic backup ring interposed between the torodial sealing element and the first backup ring, both backup rings being of generally truncated triangular shape, in cross section; and a metallic insulating sleeve, surrounding the actuating sleeve while being substantially fully radially spaced therefrom, via a peripheral air gap, except for a band portion at one end thereof, this band being interference-fitted on a corresponding portion of the actuating sleeve and including a plurality of axially-extending, spaced, scalloped recesses defining an additional insulating air space and having spaced boundaries that provide surfaces for the interference-fitting.
