C500 series wing nut couplings feature a brass body and a zinc-plated carbon steel wing nut and come standard with buna-N (Nitrile) seals.
The brass construction makes these couplings the ideal choice for water-based applications while the thread-to-connect wing nut design allows for connection and disconnection by hand.
C500 Series couplings can be connected under residual pressure, allow for bi-directional flow, and are commonly found on trailers and in the oil and gas markets.
