Abstract
A ground joint coupling for hoses comprises a stem, a ground joint head formed at a first end portion of the stem, a spud having a first end portion, a molded polymeric annular seat adapted to be positioned between the ground joint head of the stem and the first end portion of the spud, and a nut for connecting the stem to the spud and for compressing the seat between the ground joint head of the stem and the first end portion of the spud. The seat may be made of polytetrafluoroethylene, ultra high molecular weight polyethylene, polyetheretherketone compounds, polyphenylene sulfide compounds, fluoroplastic compounds, or acetal compounds, and the seat may include a filler, such as glass, moly, carbon, bronze, graphite, calcium fluoride, polyphenoline-sulfide, ceramics, silica-based minerals, or combinations thereof.
