Aeroquip 501-12-12S Hydraulic Quick Disconnect Coupler Fitting

Aeroquip 501-12-12S Hydraulic Quick Disconnect Coupler Fitting is a 3/4-inch, steel-bodied quick-connect designed for fast, leak-free hydraulic connections in industrial and mobile equipment. It’s part of Aeroquip’s 5600-series Industrial Interchange family; the 12-12S designation corresponds to a 3/4-inch coupling, with the 5602-12-12S variant specifying a 3/4-14 NPT female thread on one end and a push-to-connect end on the other for rapid, tool-free disconnection. The NPT end accepts a male pipe thread from a block or valve, ensuring a secure seal when connected, while the push-to-connect side provides quick attachment of a corresponding line. Typical applications include hydraulic fluid transfer in industrial machinery, agricultural and construction equipment, and in-plant manufacturing where durable, easily serviced connections are required. These fittings are designed to be compatible with other Aeroquip 5600-series quick disconnects in the same 3/4-inch size class.
