Blanking Plug CEL M30x2 22L

The CEL M30x2 22L blanking plug is a hydraulic plug designed for closing hydraulic hose ends and other compatible connectors ending with a nut. The product belongs to the L light series and is intended for 22L size connections, equipped with an M30x2 metric thread nut. Sealing is achieved by compressive pressure of appropriately matched conical surfaces during nut tightening.

The blanking plug belongs to the TN 296 group of elements, referred to in English documentation as Blanking Plug for Tube Ends. It is used in hydraulic systems utilized in agriculture, horticulture, forestry, construction, and industry. It allows for closing the appropriate hose end during assembly, repair, maintenance, or modernization of a hydraulic system.

Application of the CEL 22L blanking plug in power hydraulics

The CEL M30x2 22L blanking plug is used for blanking hydraulic hose ends equipped with an appropriate union nut. It can be used during disconnection of hoses from hydraulic system elements, replacement of components, maintenance work, and closing unused hose ends.

The product is used in the hydraulics of agricultural machinery, horticultural devices, forestry equipment, construction machinery, and industrial installations. An appropriately selected plug allows for closing a compatible hose end without the need for permanently modifying its structure.

L light series – 22L connection size

The 22L designation identifies a variant belonging to the L light series. The CEL M30x2 plug is intended for use with appropriately selected hose ends of this series. When assembling hydraulic fittings, check the compatibility of the nut, connection size, and geometry of the sealing surfaces.

Light series L blanking plugs should not be automatically replaced with heavy series S elements. Individual versions may differ in dimensions and the construction of mating parts. Simply matching the thread does not guarantee a proper connection seal.

Conical compression seal – principle of operation

The CEL M30x2 22L blanking 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 using a mating nut. Tightening causes a clamping force that allows for closing the hydraulic connection.

Correct tightness depends on the compatibility of the plug and hose end geometry, the condition of the mating surfaces, and proper installation. Scratches, dirt, and deformations of the conical surfaces can cause leaks. The CEL plug is not a universal blanking plug intended for direct screwing into any threaded hole.

M30x2 thread – connection parameters

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 CEL 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, both the M30x2 thread and the 22L size, as well as the type of sealing surface, should be considered. Thread compatibility alone does not mean the plug will be suitable for every hydraulic connector.

Catalog designations Ermetto, Rastelli-Raccordi, Cast and Vitillo

The CEL M30x2 22L plug can be identified based on the designations used by hydraulic fitting manufacturers. According to Ermetto, it appears as ROV 22-L, according to Rastelli-Raccordi as TS296-22L, according to Cast as 108010.1, while according to Vitillo as ATME22L.1.

Catalog designations help in identifying the correct variant when searching for replacement parts, comparing technical documentation and assembling hydraulic connections. Before using a replacement, confirm the compatibility of its construction and dimensions with the requirements of the specific hose end.

Hydraulic tube end blanking plug TN 296

The TN 296 designation refers to the type of blanking plug intended for closing tube ends. The English name Blanking Plug for Tube Ends defines its function as a plug for appropriate hydraulic hose ends.

The blanking plug is pressed by a nut located at the end of the hose. For this reason, it must be distinguished from plugs intended for direct screwing into threaded holes of distributor bodies, valve blocks and other hydraulic elements.

Protecting hoses during repairs and maintenance

During service work, it may be necessary to disconnect a hose from an actuator, distributor or other component. An appropriately selected CEL 22L 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 plug is to remain installed while the system is operating under pressure, the permissible parameters of the complete connection must be confirmed beforehand. The L light series designation alone does not confirm a specific operating pressure.

Selecting a CEL M30x2 plug for a hose end

Before selecting a plug, check the type of hose end, the mating nut thread and the connection series. For the CEL M30x2 22L plug, a compatible L light series end with the appropriate nut and matched conical surfaces is required.

When replacing a previously used blanking plug, the designations ROV 22-L, TS296-22L, 108010.1 and ATME22L.1 are helpful. They allow for more accurate identification of the correct variant and reduce the risk of confusing the plug with elements of other sizes.

Installation of the CEL M30x2 22L plug and 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 correct position and pressed using a compatible nut.

Tightening should be performed in accordance with the requirements of the connection system used. Do not attempt to eliminate leaks by over-tightening damaged components. After completing installation, check for tightness and ensure that the complete connection meets the operating conditions of the system.
