Oleo Tecnica BSP Parallel Threaded Stubs with Double O-Ring Seat are key connection components for fluid management in hydraulic circuits operating under medium-high and very high pressure conditions. The geometric configuration features a BSP parallel threaded connection combined with an advanced sealing system based on a double O-Ring seat. This construction ensures complete system leak tightness and prevents fluid leakage even under severe mechanical stress and significant pressure fluctuations.<\/p>\n

Construction Features and Materials<\/h3>\n

The standard production of these components uses A105 steel or materials with similar mechanical properties (SFS designation). For applications in chemically aggressive environments or where superior corrosion resistance is required, the entire range is available in AISI 316L stainless steel (SFX designation). Regardless of the selected base material, all stubs undergo a Cr3 zinc-plated surface treatment. This process provides the component with high resistance to oxidation and wear, extending its operational reliability.<\/p>\n

Series 3000 Technical Specifications<\/h3>\n

Series 3000 of Oleo Tecnica BSP Parallel Threaded Stubs with Double O-Ring Seat is designed to handle different working pressures in direct relation to the nominal size of the fitting. Specifically, for sizes 1\/2″, 3\/4″ and 1″, the maximum recommended working pressure reaches 345 Kg\/cm2. As the diameter increases, the pressure limit decreases according to the fluid thrust area: the 1″1\/4 size supports up to 276 Kg\/cm2, while the larger 1″1\/2 and 2″ versions ensure safe operation up to 207 Kg\/cm2. Component weight ranges from a minimum of 0.15 Kg (1\/2″) up to 1.10 Kg (2″).<\/p>\n

Series 6000 Technical Specifications<\/h3>\n

For heavy-duty hydraulic circuits operating under very high pressure conditions, Series 6000 offers superior sealing performance and structural integrity. Unlike Series 3000, the maximum recommended working pressure for Series 6000 remains fixed and constant at 414 Kg\/cm2 for all sizes, from 1\/2″ up to 2″. This consistent performance makes it possible to standardize components in complex high-pressure systems without derating sealing capacity in larger-diameter sections. The weights are proportionally higher than those of Series 3000, ranging from 0.16 Kg to 1.76 Kg, in order to withstand the greater stresses generated. Both series use the same O-Ring types (from type 4075 to type 4225), thereby simplifying spare parts procurement.<\/p>\n
