Description
Designed to meet the most demanding requirements of hydraulic circuits, Oleo Tecnica 90° BSP Threaded Flanges represent a high-quality solution for interconnecting components in high-pressure environments. The 90-degree geometry combined with GAS (BSP) threading facilitates installation in confined spaces, while ensuring optimised flow direction and reducing pressure losses within the hydraulic system.
Construction Features and Materials
Structural reliability is at the core of these components. The flanges are manufactured using high-quality materials to withstand continuous mechanical stress and thermal variations. Two main material variants are available: S355 carbon steel, ideal for standard industrial applications requiring high mechanical strength, and AISI 316L stainless steel, intended for corrosive environments. Some dimensional models are machined directly from bar stock, providing greater material uniformity and structural strength. The sealing system is ensured by the precise O-ring housing, which is essential for preventing any hydraulic fluid leakage even under the most intense pressure peaks.
Pressure Specifications and Available Series
Operating performance varies according to the selected dimensional series, covering a wide range of requirements for both light-duty and heavy-duty machinery:
- Series 3000: This series offers a maximum recommended working pressure range that varies according to component size. It starts at 345 Kg/cm² for the most compact sizes (up to 1″), then progressively decreases to 276 Kg/cm² (1″1/4), 207 Kg/cm² (1″1/2 and 2″), and finally 172 Kg/cm² for the largest 2″1/2 GAS variant.
- Series 6000: Specifically developed for heavy-duty applications, Series 6000 maintains a constant and extremely high maximum working pressure of 414 Kg/cm², covering connections ranging from 1/2″ GAS up to 2″ GAS.
Fastening Configurations and Designations
Installation flexibility is ensured by the multiple supply options available. Oleo Tecnica 90° BSP Threaded Flanges can be ordered as individual components or supplied in complete assembly kits. Ordering designations facilitate the exact identification of the required parts:
- Flange only: Identified by the code AFS…90G (for S355 versions) or AFX…90G (for AISI 316L versions).
- Flange complete with metric screws: Code AFS…90GM or AFX…90GM. The set includes the flange, metric screws, spring washers and sealing O-ring.
- Flange complete with UNC screws: Code AFS…90GU or AFX…90GU. The set includes UNC screws, spring washers and O-ring. It is important to note that the UNC screw set is available exclusively in the carbon steel version.
