5100 Series Low Spill Connect Under Pressure Quick Disconnect, Male Half, -24 Coupling, 1-1/2-11-1/2 Female Pipe

This male half coupling is indeed part of the 5100 series and will connect to a corresponding female half. Just verify the coupling size (-24) and female pipe thread (1-1/2-11-1/2) match your existing setup.

Up to 500 psi, you can connect it without depressurizing the line first. That's one of the main reasons this fitting gets used on dump trucks and refuse vehicles where stopping to bleed pressure out of a wet line just isn't practical. The tubular valve design also keeps fluid loss minimal when you disconnect, so you're not dealing with a spill every time you break the connection.
