CES M20x1.5 12S Plug

The CES M20x1.5 12S plug is a hydraulic blanking plug designed for closing hydraulic hose ends and other compatible connectors terminated with a nut. The product belongs to the heavy series S and works with a nut with an M20x1.5 metric thread. Sealing is achieved by pressing properly fitted conical surfaces during nut tightening.

The blanking plug belongs to the TN 296 product group, referred to in English documentation as Blanking Plug for Tube Ends. It is used in power hydraulics for agricultural, orchard, forestry, and construction machinery, as well as industrial equipment. It allows for closing a hose end during assembly, maintenance, repair, or system modernization.

Application of the CES 12S plug in power hydraulics

The CES M20x1.5 12S plug is used for closing hydraulic hose ends equipped with an appropriate swivel nut. It can be used when disconnecting hoses from hydraulic receivers, replacing components, technical inspections, and securing unused ends of oil installations.

The product is used in hydraulic systems of agricultural machines, orchard equipment, forestry equipment, construction machinery, and industrial installations. A properly selected blanking plug allows for closing a compatible hose end without the need for permanent modification.

Heavy series S – connection size 12S

The 12S designation identifies a variant belonging to the heavy series S. The CES M20x1.5 plug is designed to work with properly selected hose ends of this series. When assembling fittings, check the compatibility of the nut, connection size, and sealing surfaces.

Heavy series S elements should not be automatically replaced with light series L blanking plugs. Individual versions may differ in dimensions and the construction of mating surfaces. The fit of the M20x1.5 thread alone does not guarantee a leak-tight connection.

Conical compression seal – operating principle

The CES plug uses a seal achieved by pressing properly fitted conical surfaces. The blanking element is placed in the hose end and then pressed using a mating nut. During tightening, a clamping force is generated that allows for closing the hydraulic connection.

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

M20x1.5 thread – meaning of the designation

M20x1.5 denotes a metric thread with a nominal diameter of 20 mm and a pitch of 1.5 mm. In the case of the CES plug, this dimension refers to the thread of the mating nut, which is responsible for pressing the blanking plug against the hydraulic hose end.

When selecting, check not only the thread size but also the 12S series and the hose end design. Thread size compatibility does not automatically mean the possibility of using the plug in every hydraulic connection.

Catalog designations Ermetto, Rastelli-Raccordi, Cast, and Vitillo

The CES M20x1.5 12S plug appears under designations used by hydraulic fitting manufacturers. According to Ermetto, it is designated as ROV 12-S, according to Rastelli-Raccordi as TS296-12S, according to Cast as 108017.1, and according to Vitillo as ATME12S.1.

Catalog designations facilitate the search for spare parts, comparison of technical documentation, and assembly of hydraulic connections. Before using a replacement, confirm the compatibility of its dimensions and design with the requirements of a specific connector.

Blanking plug for hydraulic hose ends TN 296

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 its function as a plug for appropriate hydraulic hose ends.

The plug is pressed by a nut located on the hose end. For this reason, it should be distinguished from plugs screwed directly into the bodies of directional control valves, valve blocks, or other hydraulic components.

Securing hydraulic hoses during service

During service work, it may be necessary to disconnect a hose from an actuator, distributor, or other component. A properly selected CES 12S plug allows for closing a hose end equipped with a compatible nut. It helps limit the entry of contaminants and the outflow of residual oil during work on a depressurized system.

If the blanking plug is to remain installed while the system is operating under pressure, the allowable parameters of the complete connection must be confirmed beforehand. The heavy series S designation alone does not determine the maximum working pressure of the finished assembly.

Selecting the CES M20x1.5 plug for a hose end

Before purchasing, check the size of the hose end, the mating nut thread, and the connection series. For the CES M20x1.5 12S plug, an appropriate heavy series S end is required, equipped with a compatible nut and matching conical surfaces.

When replacing an existing blanking plug, the designations ROV 12-S, TS296-12S, 108017.1, and ATME12S.1 are helpful. They allow for more accurate identification of the correct variant and reduce the risk of confusing it with elements of other sizes.

Installation of the CES M20x1.5 12S plug and leak check

Before installation, turn off the device and safely depressurize the hydraulic system. Then, clean the hose end, check the condition of the conical surfaces and the nut thread. The plug should be placed in the correct position and pressed using a properly selected nut.

Tightening should be carried out according to the requirements of the connection system used. Do not attempt to eliminate leaks by over-tightening damaged components. After installation is complete, it is necessary to check the tightness of the connection before restarting the system.
