The Quick Connect Coupler (MPN: 100FSS) is a reliable solution for fast, tool-free connections in fluid transfer systems. This female coupler, or socket, allows a corresponding plug to be quickly inserted and locked into place by manually retracting the sleeve. The straight-thru design means there are no internal valves, providing a smooth and unrestricted flow path, which is ideal for applications where minimal pressure drop is required.


Constructed from durable 303 stainless steel, this coupler offers excellent resistance to corrosion, rust, and wear. The Buna-N/Nitrile rubber seal provides a reliable, leak-proof connection, making it suitable for a wide range of general-purpose applications as well as for specialized use in the Tommy Water Treatment Center and the All-in-One Pump Station World Model. This coupler is designed to a standard industrial interchange, ensuring compatibility with similarly sized and designed plugs.
