1951-12 Split Flange Half Code 61 | Forged Steel 3/4 Inch | 3000 PSI

Product Description

The 1951-12 Split Flange Half Code 61 is a heavy-duty hydraulic flange component designed to clamp compatible hose fittings and adapters to SAE Code 61 flange ports. This product includes the forged steel flange half only and is supplied without bolts or O-rings. It is manufactured specifically for 3/4 inch nominal flange connections used in industrial and mobile hydraulic systems.

This flange half is commonly used by hydraulic mechanics, maintenance technicians, and engineers when assembling or replacing hose ends on pumps and valve blocks. It offers full interchangeability with other 1951 series Code 61 split flange hardware and meets accepted hydraulic industry compliance requirements.

Split flange halves such as the 1951-12 play a critical role in creating strong and vibration-resistant hydraulic assemblies. This method delivers improved stability in high-flow circuits and prevents loosening in equipment exposed to constant movement and pressure pulses.

Constructed from forged carbon steel, the 1951-12 flange half provides excellent structural strength and precise alignment with standard SAE flange patterns. The anti-corrosion coating protects the surface from rust and environmental wear, making it suitable for outdoor machinery, hydraulic manifolds, and demanding worksites.
