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

It is the male half (plug) in the 5100 Series with a -20 coupling size, and the pipe end is 1-1/4-11-1/2 female NPTF.

You sure can connect this even with up to 500 psi of pressure. It's made to handle that without any trouble.

Fluid loss on disconnect is rated at 0.70 cubic centimeters, which is about as close to nothing as you're going to get in a working hydraulic line. The tubular valve construction is what keeps that number that low. For dump and refuse applications where you're connecting and disconnecting regularly, that kind of spill reduction adds up fast and keeps the ground under your rig a lot cleaner over time.

For on highway hydraulic wet lines and dump or refuse vehicles, the 5100 Series low spill plug uses a tubular valve design that keeps fluid loss very low during disconnect. It is also built to limit air inclusion during hookup, which helps keep the system from getting spongy.
