Steel Flush Face Hydraulic Quick-Connect Coupler, 1/2" Coupling X 1-1/16"-12 Sae This Dixon 4HTO series steel flush face push-to-connect hydraulic quick connect coupler has an SAE/ORB connection end, and connects to a flush face hydraulic quick connect plug to minimize fluid loss. The SAE/ORB connection provides lower fluid leakage at high pressure levels. Steel provides better weldability and greater rust resistance than wrought iron. This automatic coupler has a push-to-connect operation, shuts off when disconnected, and has a sleeve lock to guard against accidental disconnection. This fitting's maximum working pressure (MWP) is 4,250 pounds per square inch (psi) (289.12 bar). This coupler conforms to the International Organization for Standardization (ISO) 16028 specifications for hydraulic fluid power, flush-face type, quick-action couplings. It is used for hydraulic applications in industrial operations.
