ISO B Series hydraulic quick-connect coupling bodies are the female end of coupling sets. Also called sockets, they accept coupling plugs (nipple or male ends) for hydraulics and fluid transfer. ISO B Series hydraulic quick-connect couplings are equivalent to and interchange with other ISO B Series couplings. These couplings handle both high and low pressures and the self-sealing poppet valves provide double shut-off on both female and male halves. ISO B couplings are used with high-pressure fluid transfer, cleaning equipment, and food and chemical processing. This listing is for each.
