Oleo Tecnica Socket-Weld Counter Flanges for Metric Tube are a technical connection solution designed for use in hydraulic systems and circuits. These components ensure a secure and leak-tight connection for metric tubes, preserving the integrity of the hydraulic flow. Their construction features a socket-weld configuration designed to facilitate insertion of the tube and subsequent welding, thereby creating a joint with high mechanical reliability. Correct application of these counter flanges supports strict control of hydraulic fluid contamination and helps maintain optimal operating pressures within the system, in accordance with the component’s rated parameters.<\/p>\n

Pressure Specifications and Available Series<\/h3>\n

The range of Oleo Tecnica Socket-Weld Counter Flanges for Metric Tube is structured around two main product lines designed to meet different hydraulic sealing requirements: Series 3000 and Series 6000.<\/p>\n

For Series 3000, the maximum recommended working pressure varies directly according to component size. It is 345 Kg\/cm\u00b2 for 1\/2″, 3\/4″ and 1″ sizes; decreases to 276 Kg\/cm\u00b2 for the 1″1\/4 size and to 207 Kg\/cm\u00b2 for the 1″1\/2 size.<\/p>\n

Series 6000, intended for higher hydraulic loads, provides a maximum recommended working pressure of 414 Kg\/cm\u00b2 for 1\/2″, 3\/4″ and 1″ sizes. For the larger sizes, the nominal pressure rating is 276 Kg\/cm\u00b2 for 1″1\/4 and 320 Kg\/cm\u00b2 for 1″1\/2.<\/p>\n

It is essential to emphasize a key technical principle: the stated maximum recommended working pressure is based exclusively on the structural strength of the flange. The actual maximum working pressure of the complete hydraulic system is determined and limited by the thickness and material quality of the tube used.<\/p>\n

Construction Features and Materials<\/h3>\n

The strength and reliability of the counter flanges are ensured by the use of high-performance metallic materials. The components are available in two primary construction variants: S355 steel and AISI 316L stainless steel. S355 steel provides high strength and is suitable for most standard hydraulic applications. AISI 316L offers superior resistance, making the components ideal for demanding operating environments. The geometric design includes different dimensional parameters proportional to the size of the metric tube, ensuring strict tolerances and weights ranging from a minimum of 0,26 kg up to 1,94 kg for the largest Series 6000 models.<\/p>\n

Ordering Designation and Fastening Holes<\/h3>\n

Oleo Tecnica Socket-Weld Counter Flanges for Metric Tube are available with advanced fastening-hole options for maximum versatility. The models can be identified through specific ordering designations. Counter flanges with metric threaded fastening holes are identified by the codes GFS…SA for S355 versions and GFX…SA for AISI 316L variants. For Series 3000, the specified metric threads are M8 for the 1\/2″ size, M10 for 3\/4″, 1″ and 1″1\/4 sizes, and M12 for the 1″1\/2 size. For Series 6000, progressive metric threads from M8 up to M16 are used. Alternatively, counter flanges with UNC threaded fastening holes are available, identified by the codes GFS…SAU (S355) and GFX…SAU (AISI 316L). Their threads range from 5\/16″ to 1\/2″ for Series 3000 and from 5\/16″ up to 5\/8″ for Series 6000.<\/p>\n
