Hydraulic Fitting, Gates Coupling, 3/4 CRIMP X 12 MJIC 90, 12G-12FJX90S

The Gates 12G-12FJX90S MegaCrimp Hydraulic Hose Fitting is a heavy-duty 90° elbow coupling designed for secure, leak-free hydraulic connections in demanding applications. Built for 3/4" hose (dash size -12), this fitting features a female JIC 37° flare swivel connection for reliable sealing and easy installation.

Part of the trusted Gates MegaCrimp® series, this fitting uses a patented “C” insert design that ensures even crimping force and a consistent, leak-resistant seal across a wide range of hose types. The Full-Torque Nut™ technology helps prevent damage from over-tightening while improving long-term reliability.

The 90° short-drop elbow configuration is ideal for tight routing and space-constrained installations. Constructed from steel with TuffCoat™ plating, it offers superior corrosion resistance and durability in harsh environments.
