Overview and Applications of Threaded Counter Flanges<\/h3>\n

Oleo Tecnica NPT Threaded Counter Flanges represent a high-quality construction solution for the hydraulic sector and for fluid contamination control. Designed to withstand demanding duty cycles, these counter flanges ensure optimal mechanical and hydraulic sealing, which is essential for the safety and efficiency of the system. NPT (National Pipe Thread) threading provides a precise and reliable tapered connection, helping to prevent fluid leakage even under demanding operating conditions.<\/p>\n

Series 3000 and 6000 Specifications<\/h3>\n

The product range is divided into two main categories to meet different pressure requirements: Series 3000 and Series 6000. Series 3000 covers a very wide dimensional range, from 1\/2″ up to 5″. The maximum recommended working pressure for this series varies according to component size: it starts at a maximum of 345 kg\/cm\u00b2 for smaller sizes (up to 1″), then progressively decreases to 276 kg\/cm\u00b2 for the 1″1\/4 size, 207 kg\/cm\u00b2 for models up to 2″, 172 kg\/cm\u00b2 for 2″1\/2, 138 kg\/cm\u00b2 for 3″, and down to 34 kg\/cm\u00b2 for the larger versions from 3″1\/2 to 5″.<\/p>\n

Series 6000 is engineered for very high-pressure applications. Available in sizes ranging from 1\/2″ to 3″, this series maintains a constant maximum recommended working pressure of 414 kg\/cm\u00b2 across all listed models.<\/p>\n

Construction Features and Materials<\/h3>\n

The durability and structural strength of Oleo Tecnica NPT Threaded Counter Flanges are determined by the use of high-quality materials. Designers and purchasing managers can select between two material options: S355 steel for standard high-strength applications, or AISI 316L stainless steel for operating environments requiring maximum corrosion resistance.<\/p>\n

In addition, the ordering designation system makes it easy to identify the fastening-hole configuration. Standard versions (GFS…N for S355 and GFX…N for AISI 316L) feature metric threaded fastening holes, while versions designated with the “U” suffix (GFS…NU and GFX…NU) incorporate UNC threaded fastening holes.<\/p>\n
