6600 Series, Nipple
Parker 6600 Series nipples are used in hydraulic fluid systems for a secure and leak-free connection of hoses or pipes with compatible female ORB / NPTF type port configurations. They are made of steel with zinc-chromate plating for corrosion resistance and improve durability. These couplers have double shut-off poppet valves that prevent the flow of fluid in both directions and include nitrile seals to resist oils, fuels, hydraulic fluids, water and other chemicals. These nipples are designed to be interchangeable with other quick-disconnect couplings complying with ISO 7241-1 Series A standards.
