Half flanges are essential connection components in hydraulic systems, designed to ensure robust, leak-free connections in systems operating at medium and high pressures. When combined with specific O-Ring seals, they provide superior leak-tight performance compared with traditional threaded connections, making them essential in the presence of vibrations, thermal shocks and pressure peaks. For layouts requiring maximum structural rigidity and uniform distribution of the clamping load, Oleo Tecnica one-piece half flanges represent the standard solution for optimal and safe in-line connections between rigid or flexible piping.
Compatibility with manifold blocks, valves and pumps is ensured by the different drilling patterns and structural configurations available. In systems designed according to European metric standards, Oleo Tecnica one-piece halg flanges with metric threaded mounting holes ensure precise interfaces, while machinery designed according to British or American standards requires the use of Oleo Tecnica one-piece half flanges with UNC threaded mounting holes. In addition, in maintenance, repair and overhaul (MRO) applications where space is limited, Oleo Tecnica two-piece half flanges allow quick side installation, enabling assembly in two halves to reduce machine downtime without requiring complete disassembly of the system.
These components are widely used across a broad range of industries, from hydraulic power units and earthmoving machinery to industrial presses. In addition to drastically reducing the risk of fluid leakage, their installation helps prevent mechanical twisting of hoses and pipes during assembly and requires significantly lower tightening torque than large-diameter threaded fittings. This simplifies maintenance operations while significantly improving the reliability and safety of the entire hydraulic system.
