5100 Series Low Spill Connect Under Pressure Quick Disconnect, Male Half, -16 Coupling, 1-11-1/2 Female Pipe

This is the male half for a -16 quick disconnect, and the pipe end is 1-11-1/2 female NPTF. It’s the 5100-S2-16B plug, so it matches that thread and coupling size combination.

Up to 500 psi, you can connect the two halves without bleeding the line down first. That's one of the main reasons this coupling gets used on dump trucks and refuse vehicles where stopping to depressurize the system just isn't practical. Beyond 500 psi you'd want to relieve pressure before connecting, but for most on-highway wet line work it handles the job without that extra step.

Up to 500 psi, you can connect the halves without bleeding the system down first. That's one of the main reasons this coupling gets spec'd on dump trucks and refuse vehicles where shutting things down to swap connections just isn't practical. The tubular valve design also keeps fluid loss at disconnect to around 0.35 cubic centimeters, so you're not making a mess every time you pull it apart.

For on-highway hydraulic wet lines and the kind of connect and disconnect you see on dump and refuse trucks, the 5100 Series is a solid fit. The tubular valve design is made to keep fluid loss very low on disconnect, and it also keeps air inclusion low when you hook back up, which helps the system run cleaner.

This quick disconnect is designed to connect against pressure up to 500 psi, so it should work for your application.
