High pressure quick connect couplings offered by Maxbar are available with special variations, including different end fittings, materials, mounting options, pressure ratings and more. Standard high pressure quick couplings from Walther Precision come with standard bores, end fitting sizes, and are available with either one of both sides with valves. Most high pressure couplings come in either steel or stainless steel. Although grouped in the HP Series family, the subsea version of the high pressure series is distinctly different.
