Hydraulic Fitting, 3/4"X3/4" HEAVY Flange

Hydraulic Fitting, 3/4"X3/4" HEAVY Flange

The 12G-12FLH Hydraulic Fitting is a heavy-duty Code 62 O-ring flange hydraulic hose fitting designed for high-pressure hydraulic systems. With 3/4" hose size and a 3/4" heavy flange connection, it provides a secure, leak-resistant connection commonly used on construction equipment, agricultural machinery, and industrial hydraulic systems. Built from steel for durability and strength, this fitting is designed to handle demanding hydraulic applications with working pressures up to around 6,000 PSI, helping keep hydraulic systems sealed, stable, and operating smoothly—even when the equipment is working as hard as you are.
