CEL Plug M18x1.5 12L – TN 296 hydraulic blanking plug

The CEL M18x1.5 12L plug is a hydraulic fitting element designed for blanking hydraulic hose ends and other compatible connectors ending with a nut. The design of the plug allows for a connection with a conical compression seal, formed during nut tightening. The product is used to close properly prepared tube ends in power hydraulic systems.

The plug is designed for light series 12L connections, working with a metric thread nut M18x1.5. It belongs to the TN 296 blanking plug group, also known as Blanking Plug for Tube Ends. It is used in hydraulic systems of agricultural, orchard, forestry, and construction machinery, as well as industrial equipment.

Matching nut thread: M18x1.5.
Connection series: L – light.
Seal type: conical, compression during tightening.
Designation according to Ermetto: ROV 12-L.
Designation according to Rastelli-Raccordi: TS296-12L.
Designation according to Cast: 108007.1.
Designation according to Vitillo: ATME12L.1.
Type designation: TN 296.
English name: Blanking Plug for Tube Ends.
Purpose: blanking hose ends and connectors equipped with an appropriate nut.

Application of the CEL 12L plug in power hydraulics

The CEL M18x1.5 12L plug is used to close properly prepared hydraulic hose ends. It is useful during the assembly of new installations, repair of oil systems, disconnection of hydraulic receivers, and securing unused tube connections.

The product is used in the hydraulics of agricultural machinery, orchard equipment, forestry and construction equipment, and industrial installations. It can be used during work on hydraulic hoses equipped with compatible union nuts. Proper selection of the plug allows closing a hose end without the need to rebuild the rest of the installation.

Conical compression seal – principle of operation

The CEL plug utilizes a seal formed by the pressure of properly matched conical surfaces. After placing the blanking plug in the hose end, the nut is tightened, causing mechanical pressure on the components. In this way, it is possible to close the connection and cut off the flow of the medium through the secured end.

Tightness depends on the compatibility of the plug's geometry and the matching connector, the condition of the conical surfaces, and correct assembly. The plug is not a universal cap for any threaded hole. Its design requires a proper hose end equipped with a nut that provides pressure.

M18x1.5 thread and 12L light series

The M18x1.5 designation refers to a metric thread with a nominal diameter of 18 mm and a pitch of 1.5 mm. In the case of the CEL plug, this parameter defines the thread of the nut matching the blanking plug. The 12L symbol identifies the size belonging to the light series of metric tube connections.

When selecting, one should check not only the M18x1.5 thread but also the 12L size and the tube end profile. The compatibility of the thread itself does not guarantee a proper seal. Do not use the plug with components of different matching surface geometry.

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

The CEL M18x1.5 12L plug appears under designations used in hydraulic fittings manufacturers' catalogs. According to Ermetto, it corresponds to the symbol ROV 12-L, according to Rastelli-Raccordi to the designation TS296-12L, according to Cast to number 108007.1, and according to Vitillo to designation ATME12L.1.

Catalog designations help identify the correct type of blanking plug during installation repairs, ordering parts, and comparing technical documentation from different manufacturers. Before using a replacement element, confirm the compatibility of its dimensions and design with the existing hydraulic connection.

Blanking plug for tube ends TN 296

The TN 296 type defines a group of elements intended for blanking tube ends. The English name Blanking Plug for Tube Ends indicates the product's function as a plug closing the end of a tube. The design of the blanking plug is adapted to work with an appropriate screw connection and conical seal.

Unlike standard plugs screwed into a valve block body or other threaded hole, the CEL plug is pressed by a nut located at the end of the tube. For this reason, when completing fittings, special attention should be paid to the type of connection being blanked.

Securing hoses during repairs and modernizations

During hydraulic system repair, it may be necessary to disconnect a hose from a receiver, valve block, or other installation element. A properly selected CEL plug allows for closing the free end equipped with a compatible nut. It helps limit the ingress of contaminants and the leakage of residual oil from the depressurized hose.

The blanking plug can also be used when changing hydraulic hose configurations. If the connection is to remain closed while the system is operating under pressure, it is necessary to previously confirm the permissible parameters for the entire assembly.

Selecting the CEL M18x1.5 plug for a hose end

Before purchasing, identify the type of hose end, the nut size, and the design of the sealing surface. For the CEL 12L plug, the correct thread size for the matching nut is M18x1.5. Compatibility of the conical contact surface should also be checked.

When replacing a currently used element, it is worth comparing the designations ROV 12-L, TS296-12L, 108007.1, and ATME12L.1. This allows for reducing the risk of confusing the CEL plug with another type of hydraulic blanking plug.

Assembly and leakage check of the CEL 12L plug

Before starting work, turn off the device and safely depressurize the hydraulic installation. The hose end should be cleaned, and the conical surfaces checked for damage. Then, the plug should be placed in the appropriate position and pressed using the matching nut.

Tightening should be performed according to the requirements of the connection system used. Do not compensate for a damaged sealing surface with excessive force. After assembly, it is necessary to check for leaks and confirm the permissible operating conditions of the blanked end.
