Oleo Tecnica CETOP Flange Assembly with Blind Stub and Metric Screw Set

Description

Operating Principle and Applications

Oleo Tecnica CETOP Flange Assembly with Blind Stub and Metric Screw Set is an essential technical component for safe closure, isolation and end flanging in hydraulic circuits. Developed to withstand the mechanical stresses typical of industrial hydraulic systems, it ensures system integrity and prevents fluid leakage, while effectively supporting fluid contamination control protocols. Its construction allows quick and easy use on high-pressure line ends, where sealing performance and the operational safety of fittings are critical parameters.

Construction Features and Materials

The product is supplied as a preassembled kit designed to optimize installation and testing procedures. The standard set includes a robust CETOP flange manufactured from S355 steel, precisely coupled with a blind stub machined with a dedicated O-ring seat. The stub is available as standard in A105 carbon steel or AISI 316L stainless steel, allowing maximum adaptability to the aggressiveness of the working environment. Mechanical fastening is ensured by four metric socket head cap screws (TCE) and four Grower-type spring lock washers, completed by the sealing O-ring. Upon specific request, the manufacturer can supply the entire CETOP flange in AISI 316L. The correct ordering designation uses the base identifier for standard materials (e.g. GCET…C…) and adds the suffix X (e.g. GCETX…C..) for structural configurations in AISI 316L stainless steel.

Technical Specifications: Series 250 and Series 400

The technical documentation divides the range into two design categories according to the maximum recommended working pressure.

Series 250 is rated and recommended for operation at maximum pressures of up to 250 Bar. This range covers nominal sizes from a minimum of 3/8 inch up to 4 inches. Component weights range from a minimum of 0.20 Kg for the most compact sizes up to 11.30 Kg for the largest models such as GCET4C250. Metric fastening in this series uses screws ranging from M6x30 to M24x100.

Series 400, on the other hand, is specifically developed for extremely demanding hydraulic applications and heavy-duty cycles, withstanding a maximum recommended working pressure of 400 Bar. While maintaining the same size range (from 3/8″ to 4″), the components feature reinforced structural profiles to withstand high mechanical stress. Series 400 weights start from 0.24 Kg for the smallest size and reach 13.00 Kg in the heavy-duty 4-inch configuration (GCET4C400). The supplied screws range from M6x35 up to the robust M24x100 size.
