5100 Series Low Spill Connect Under Pressure Quick Disconnect, Female Half, -20 Coupling, 1-1/4-11-1/2 Female Pipe

This Eaton 5100 series quick disconnect is often used for on-highway hydraulic wet lines, along with dump and refuse vehicles.

You can connect it under pressure up to 500 psi without bleeding the line down first. That's one of the main reasons this fitting gets used on dump trucks and refuse trucks where stopping to depressurize the system every time just isn't practical. The tubular valve construction also keeps fluid loss down to around 0.70 cubic centimeters at disconnect, so you're not making a mess every time you pull it apart.

For on highway hydraulic wet lines and equipment like dump and refuse vehicles, the 5100 Series female half is a common fit since it is built for hydraulics and fluid transfer in those applications, with a low spill tubular valve style.

The female pipe thread on this -20 female half is 1-1/4-11-1/2, and it’s a 2-way valve style quick disconnect.
