These manual connect and disconnect couplings are commonly used in fluid transfer applications where unrestricted flow and high operating pressures are desired. Couplers are machined from solid brass or 303 stainless steel bar stock and come standard with buna-N (Nitrile) seals. Stainless steel balls, retaining rings, and springs provide max imum service life. Plugs are machined from solid brass, steel, or 303 stainless steel bar stock. Steel plugs are hardened and zinc plated for maximum service life.

Temperature Range : -20°C (-4°F) to 125°C (257°F). Interchange : Coilhose ST, Foster ST, Perfecting E, Parker ST, Holmbury HF.
