Oleo Tecnica Long BSP Parallel Threaded Stubs with Double O-Ring Seat

Description

Hydraulic Architecture and Connections

Oleo Tecnica Long BSP Parallel Threaded Stubs with Double O-Ring Seat are essential connection components in hydraulic systems, designed to handle high-pressure flows. The component geometry features a BSP parallel thread combined with a double O-Ring seat configuration, ensuring superior leak-tight sealing and minimizing the risk of leakage under hydraulic stress. The extended design facilitates installation in complex operating spaces while maintaining the mechanical performance of the circuit unchanged.

Series 3000 Technical Specifications

Series 3000 is engineered to withstand maximum recommended working pressures that vary according to the nominal size of the stub. For the smaller 1/2″, 3/4″ and 1″ sizes, the system provides a pressure rating of 345 Kg/cm². As the diameter increases, the operating pressures decrease to 276 Kg/cm² for the 1″1/4 size and 207 Kg/cm² for the 1″1/2 and 2″ models. In terms of weight, Series 3000 fittings increase proportionally: starting from 0.32 Kg for the 1/2″ configuration and reaching 1.76 Kg for the 2″ version, reflecting the material density required to withstand the pressure loads.

Series 6000 Technical Specifications

For heavy-duty applications requiring extreme hydraulic loads, Series 6000 offers enhanced and consistent performance across the entire range. Regardless of the nominal size – from 1/2″ up to 2″ – each BSP parallel threaded stub with double O-Ring seat in this series withstands a maximum recommended working pressure of 414 Kg/cm². To support these values, the dimensional parameters, particularly flange thickness and external diameters, are increased. Consequently, the weight of the components also increases, starting from 0.33 Kg (1/2″) and reaching 2.29 Kg for the largest 2″ size.

O-Ring Types and Construction Materials

The efficiency of the double seat is ensured by the use of specific O-Ring types calibrated for each size. The series uses type 4075 O-Rings for 1/2″ connections, type 4100 for 3/4″, type 4131 for 1″, type 4150 for 1″1/4, type 4187 for 1″1/2 and type 4225 for the 2″ connection, regardless of the pressure class (Series 3000 or 6000). In terms of metallurgy, the components are available in two material designations to meet different environmental and fluid requirements: A105 carbon steel (or equivalent), identified by the SFS ordering prefix and treated with a Cr3 zinc-plated surface coating for standard corrosion protection; and AISI 316L stainless steel, identified by the SFX prefix, ideal for highly aggressive environments.
