Oleo Tecnica 90° BSP Threaded Flanges with 60° Conical Seal
Oleo Tecnica 90° BSP Threaded Flanges with 60° Conical Seal ensure secure connections for high-pressure hydraulic systems. Available in Series 3000 (up to 345 Kg/cm²) and Series 6000 (up to 414 Kg/cm²), they support sizes from 1/2″ to 1″1/2. Manufactured in S355 or AISI 316L, they are available in customizable configurations with metric or UNC screws (in carbon steel), spring washers and O-Rings for precise and high-performance assembly.
The available product codes (referring to the basic “flange only” S355 ordering family) are: AFS08090B, AFS08090B038, AFS10090B, AFS10290B, AFS10490B, AFS10690B, AFS40190B012, AFS40190B038, AFS40290B, AFS40390B, AFS40490B, AFS40490BL13, AFS40590B.
Oleo Tecnica 90° BSP Threaded Flanges with 60° Conical Seal are hydraulic components designed to ensure maximum reliability in connections for circuits operating under high pressure. The 90-degree configuration with a 60-degree conical seal, combined with GAS (BSP) threading, allows precise fitting and optimal mechanical and leak-tight sealing. The components are designed for installation in complex hydraulic systems and are available in sizes ranging from 1/2″ up to 1″1/2, covering a wide range of flow-rate and piping-dimension requirements.
The range is divided into two main pressure categories, designed to meet different operating loads:
Oleo Tecnica 90° BSP Threaded Flanges with 60° Conical Seal are manufactured in two construction materials to suit the specific environmental and chemical conditions of the circuit:
The ordering system is highly modular. Components can be ordered as “Flange only” (suffix 90B), or complete with fastening and sealing sets. Complete options include a flange supplied with metric screws, spring washers and O-Ring (suffix 90BM), or with UNC screws, spring washers and O-Ring (suffix 90BU). It is important to note that complete UNC screw sets are made available by the manufacturer exclusively in carbon steel.
Assembly is supported by a diversified range of screws and O-Rings depending on series and size. The O-Rings used follow specific standards (types 4075, 4100, 4131, 4150 and 4187). For fastening, Series 3000 uses metric screws ranging from M8x30 up to M12x35 (and UNC from 5/16″x1″1/4 to 1/2″x1″3/4). Series 6000 requires larger fasteners to handle higher pressures, with metric screws from M8x30 up to M16x55 and corresponding UNC screws. This also results in an increase in overall flange weight, ranging from 0.25 Kg for the smallest version (Series 3000) up to 2.75 Kg for the 1″1/2 Series 6000 model.
