Abstract
An insulative coupling for coupling a first tube to a second tube for fluid flow therebetween. The coupling includes an insulative washer and an insulative bushing cooperating with a flange connector associated with one of the coupling body elements to provide an electrically insulative connection between the coupled tubes. An O-ring is utilized in conjunction with a face seal radially inwardly of the washer to provide a high pressure seal between the coupling elements. The washer and bushing include axially extending flange portions having snug fits with associated components of the coupling to provide for facilitated and accurate assembly.
