CES Plug M30x2 20S – heavy series hydraulic blanking plug

The CES Plug M30x2 20S is a hydraulic blanking plug designed for closing hydraulic hose ends and compatible connectors terminated with a nut. The product belongs to the heavy series S and is designed for connections with an M30x2 metric thread nut. Sealing is achieved through the compression of appropriately matched conical surfaces when tightening the nut.

The blanking plug belongs to the group of TN 296 elements, referred to in English-language documentation as Blanking Plug for Tube Ends. It is used in hydraulic power systems of agricultural, orchard, forestry, construction, and industrial machinery. It allows for securing a hose end during assembly, repair, or modernization of the installation.

Catalog type: TN 296.
English name: Blanking plug for tube ends.
Purpose: blanking hydraulic hose ends and connectors terminated with a suitable nut.

Use of CES 20S plug in power hydraulics

The CES M30x2 20S plug is used to close hydraulic hose ends equipped with a suitable union nut. It can be used during disconnection of hoses from system components, replacement of parts, maintenance work, and for securing unused ends of oil systems.

Blanking plugs of this type are used in agricultural machinery, orchard equipment, forestry equipment, construction machinery, and industrial installations. They allow for closing a suitable connection without the need for permanent hose modification. The condition for correct application is the compatibility of the plug with the nut and the design of the hose end.

Heavy series S – connection size 20S

The designation 20S identifies a connection variant belonging to the heavy series S. The CES M30x2 plug is designed to work with appropriately selected hose ends of this series. When assembling fittings, the nut size, connection design, and sealing surface geometry must be taken into account.

Elements of the heavy series S should not be automatically replaced with parts of the light series L. Individual versions may differ in dimensions and the way they work with other connector elements. A matching thread alone is not sufficient confirmation of interchangeability.

Conical compression seal – principle of operation

The CES plug uses a seal obtained through mechanical compression of mating conical surfaces. The blanking element is placed in the hose end and then pressed using a suitable nut. During tightening, a clamping force is created that allows for closing the hydraulic connection.

Tightness depends on the compatibility of the plug and hose end geometry, the condition of the mating surfaces, and correct assembly. Contamination, scratches, and deformations of the conical surfaces can cause leaks. The CES plug is not a universal plug intended for direct screwing into any threaded hole.

M30x2 thread – meaning of the designation

The M30x2 designation specifies a metric thread with a nominal diameter of 30 mm and a pitch of 2 mm. In the case of the CES plug, this parameter refers to the thread of the nut responsible for pressing the blanking plug against the hose end. The 20S size allows for determining the correct series and size of the hydraulic connection.

Before assembly, not only the M30x2 thread dimension should be checked, but also the compatibility of the 20S size and the type of sealing surface. Matching the thread alone does not guarantee a tight connection.

Catalog designations Ermetto, Rastelli-Raccordi, Cast and Vitillo

The CES M30x2 20S plug can be identified according to the designations used by manufacturers of hydraulic fittings. According to Ermetto, it appears as ROV 20-S, according to Rastelli-Raccordi as TS296-20S, according to Cast as 108020.1, while according to Vitillo as ATME20S.1.

These designations facilitate part identification when browsing technical catalogs, ordering fittings, and repairing hydraulic systems. Before using a replacement element, its dimensional, constructional, and operational compatibility must be confirmed.

TN 296 hydraulic tube end blanking plug

The TN 296 designation refers to the type of blanking plug designed for closing tube ends. The English name Blanking Plug for Tube Ends describes the function of the element as a plug for suitable hydraulic hose ends. The blanking plug is pressed by the nut located at the end of the hose, which allows for a conical seal to be achieved.

The CES plug must be distinguished from plugs screwed into distributor bodies or other threaded holes. The TN 296 variant is designed to work with a suitable hose end equipped with a union nut.

Securing hoses during service

During repair of a hydraulic installation, it may be necessary to disconnect a hose from an actuator, distributor, or other component. A properly selected CES 20S plug allows for closing a hose end equipped with a compatible nut. It helps to limit the ingress of contaminants and the outflow of oil residues during work on a depressurized system.

If the plug is to remain installed while the system is operating under pressure, the permissible parameters of the entire connection must be confirmed. The heavy series S designation itself does not constitute confirmation of a specific operating pressure value.

Selection of the CES M30x2 plug for a hose end

Before choosing a CES M30x2 20S plug, verify the hose end size, the mating nut thread, and the connection series. It is also important to match the conical surfaces. Selection based solely on thread diameter can lead to using the wrong element.

When replacing an existing plug, the designations ROV 20-S, TS296-20S, 108020.1, and ATME20S.1 are helpful. They allow for more accurate identification of the correct variant and reduce the risk of confusing elements of different series.

Assembly and leakage control of the CES 20S plug

Before assembly, turn off the device and safely depressurize the hydraulic system. Then, clean the hose end and check the condition of the conical surfaces and the nut thread. The plug should be placed in the correct position and pressed with the nut in accordance with the requirements of the connection system used.

Do not compensate for damaged sealing surfaces with excessive tightening force. After assembly is complete, it is necessary to check for leaks and verify the compliance of the complete connection with the installation's operating conditions.
