PARKER SH6-63 Hydraulic Quick Connect Hose Coupling: 3/4 in

This looks like the Parker SH6-63 hydraulic coupling plug—another ISO 7241-1 Series B fitting, but instead of a sleeve-lock mechanism, this one features a ball locking type. That means it provides a secure quick-connect design, making it easier to engage and disengage while maintaining high-pressure resistance at 3,000 psi.

A few key comparisons to the coupling socket you shared earlier:

• Shorter length: At 2-31/64", this plug is more compact than the 3-9/16" socket.
• Ball lock vs. sleeve lock: The plug uses a ball locking system, which may provide a different engagement experience compared to the sleeve-lock mechanism on the socket.
• Similar flow rate & pressure rating: Both components handle up to 106 lpm and 3,000 psi, ensuring compatibility.
