Plug CEL M22x1.5 15L

The CEL M22x1.5 15L plug is a hydraulic blanking plug designed to seal the ends of hydraulic hoses and other compatible connectors terminated with a nut. The product belongs to the light series L and works with 15L size connections equipped with an M22x1.5 metric thread nut. Sealing is achieved by pressing properly matched conical surfaces when tightening the nut.

The TN 296 type blanking plug, also referred to as a Blanking Plug for Tube Ends, is used in power hydraulics for agricultural, orchard, forestry, construction machinery, and industrial equipment. It allows for closing the appropriate hose end during assembly, maintenance, repair, or modernization of a hydraulic system.

Designation according to Vitillo: ATME15L.1.
Catalog type: TN 296.
English name: Blanking Plug for Tube Ends.
Intended use: blanking ends of hydraulic hoses and connectors terminated with a suitable nut.

Application of the CEL 15L plug in power hydraulics

The CEL M22x1.5 15L plug is used for closing hydraulic hose ends equipped with a suitable union nut. It can be used during hose disconnection from system components, replacement of parts, maintenance work, and securing unused oil system connections.

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

Light series L – connection size 15L

The 15L designation identifies a variant belonging to the light series L. The CEL M22x1.5 plug is designed to work with appropriately selected hose ends of this series. When selecting fittings, verify the compatibility of the nut, size designation, and geometry of the sealing surfaces.

Light series L elements should not be automatically replaced with heavy series S blanking plugs. Variants may differ in dimensions and connection design. Just matching the M22x1.5 thread does not guarantee a tight seal.

Conical compression seal – operating principle

The CEL plug uses a seal obtained through mechanical pressure of matched conical surfaces. The blanking element is placed in the appropriate hose end and then pressed with the matching nut. Tightening creates a clamping force that allows for closing the hydraulic connection.

Tightness depends on the compatibility of the plug and hose end geometry, the proper condition of the mating surfaces, and correct installation. Scratches, contamination, or deformation of the conical surfaces can cause leaks. The CEL plug is not a universal plug intended for direct screwing into any threaded hole.

M22x1.5 thread – meaning of the designation

M22x1.5 means a metric thread with a nominal diameter of 22 mm and a pitch of 1.5 mm. In the case of the CEL plug, this dimension refers to the thread of the nut matching the blanking plug. The nut is responsible for pressing the plug against the end of the hydraulic hose.

When selecting, not only the M22x1.5 thread should be checked, but also the 15L size and the type of sealing surface. Compatibility of the thread alone does not mean that the blanking plug will be suitable for every hydraulic connector.

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

The CEL M22x1.5 15L plug can be identified based on designations used by hydraulic fitting manufacturers. According to Ermetto, it appears as ROV 15-L, according to Rastelli-Raccordi as TS296-15L, according to Cast as 108008.1, and according to Vitillo as ATME15L.1.

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

Hydraulic hose end blanking plug TN 296

The TN 296 designation refers to the type of blanking plug designed for sealing the ends of tube lines. The English name Blanking Plug for Tube Ends describes the product's function as a plug for appropriate hydraulic hose ends.

The blanking plug is pressed by the nut located at the end of the hose. For this reason, it should be distinguished from plugs screwed directly into threaded holes of manifold bodies, valve blocks, and other hydraulic components.

Securing hydraulic hoses during service

During service work, it may be necessary to disconnect a hose from an actuator, manifold, or other component. A properly selected CEL 15L plug allows for closing the end of a hose equipped with a compatible nut. This helps limit the ingress 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, it is necessary to confirm the permissible parameters for the complete connection. The designation of the light series L alone does not determine the maximum operating pressure of the finished assembly.

Selecting the CEL M22x1.5 plug for the hose end

Before purchasing, check the type of hose end, the matching nut thread, and the connection series. For the CEL M22x1.5 15L plug, an appropriate light series L end, equipped with a compatible nut and matched conical surfaces, is required.

When replacing a previously used blanking plug, designations ROV 15-L, TS296-15L, 108008.1, and ATME15L.1 are helpful. They allow for more accurate identification of the correct variant and reduce the risk of confusing it with plugs of other sizes.

Installation of the CEL M22x1.5 15L plug and leak tightness check

Before starting 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 appropriate position and pressed using a compatible nut.

Tightening should be performed according to the requirements of the connection system used. Do not attempt to fix leaks by excessively pressing damaged elements. After installation is complete, the connection must be checked for leaks before restarting the system.
