CEL Plug M14x1,5 8L – hydraulic blanking plug TN 296

The CEL Plug M14x1,5 8L is a hydraulic fitting element designed for blanking hydraulic hose ends and other connectors finished with a suitable nut. The connection is sealed by the pressure of the mating conical surfaces during the tightening of the nut. This solution allows for closing an unused hose end and securing a disconnected part of the hydraulic installation.

The blanking plug is intended for light series 8L connections, with an M14x1,5 metric thread nut. The product belongs to the TN 296 element group, referred to in English documentation as Blanking Plug for Tube Ends. It is used in hydraulic systems of agricultural, orchard, forestry, construction, and industrial machinery.

Type designation: TN 296.
English name: Blanking Plug for Tube Ends.
Purpose: blanking hose ends and compatible connectors with a nut.

Use of the CEL 8L plug in power hydraulics

The CEL Plug M14x1,5 8L is used in hydraulic installations where it is necessary to close a hose end equipped with a suitable nut. It can be used during service work, disconnecting hydraulic receivers, hose modification, and securing installation ends.

In agriculture and orcharding, blanking elements are used during the maintenance of hydraulics in tractors, sprayers, and specialized machinery. In forestry, construction, and industry, they are used for assembly and repair work on oil systems. The condition for the correct use of the plug is the compatibility of its geometry with the hose end.

Conical compression seal – principle of operation

The CEL plug uses the principle of sealing through mechanical pressure of properly matched conical surfaces. The blanking element is placed in the hose end and then pressed by means of a mating nut. Tightening creates the force necessary to close the connection.

The effectiveness of the seal depends on dimensional compatibility, the correct cone profile, and the condition of the mating surfaces. Mechanical damage, dirt, or incorrect selection of elements can lead to leaks. The plug should not be treated as a universal cap for any threaded hole.

M14x1,5 thread and 8L size

The M14x1,5 designation refers to a metric thread with a nominal diameter of 14 mm and a pitch of 1,5 mm. In the case of the CEL plug, this dimension defines the thread of the mating nut. The 8L symbol identifies the connection size belonging to the L light series.

When selecting, not only the nut thread but also the shape of the hose end and the type of sealing surface should be considered. M14x1,5 thread compatibility does not automatically mean the plug can be used in every connection of this size.

Ermetto, Rastelli-Raccordi, Cast and Vitillo designations

The CEL Plug M14x1,5 8L can be identified according to several catalog designations used by hydraulic fitting manufacturers. According to Ermetto, the product is designated as ROV 8-L, according to Rastelli-Raccordi TS296-8L, according to Cast 108005.1, and according to Vitillo ATME08L.1.

These designations facilitate searching for elements in technical documentation, comparing catalogs, and identifying parts during the repair of existing installations. When selecting a replacement, confirm the compatibility of its design, dimensions, and operational parameters.

Blanking plug for TN 296 hydraulic hoses

The TN 296 designation refers to a type of blanking plug designed for tube ends. In English documentation, the name Blanking Plug for Tube Ends is used. The design of the plug allows it to work with a properly prepared tube end and a nut providing sealing pressure.

The CEL 8L plug can be used for temporary protection of hoses during repair work. Using a blanking plug helps limit the entry of contaminants into the installation and secures the hose end after disconnection from the mating fitting.

Selecting a plug for a hydraulic hose end

Before purchasing, check if the hose end is equipped with the appropriate M14x1,5 nut and a sealing surface compatible with the CEL 8L plug. The technical condition of the end is also important, especially the absence of damage to the conical surface.

When replacing a previously used plug, it is worth comparing its designation with the numbers ROV 8-L, TS296-8L, 108005.1, and ATME08L.1. This allows for a more accurate determination of the required element type and reduces the risk of purchasing an unsuitable plug.

Installation and leakage control of the CEL 8L plug

Before installation, turn off the device and safely depressurize the relevant part of the hydraulic system. Then clean the hose end, check the condition of the nut thread, and inspect the surfaces responsible for sealing. The plug should be placed in the correct position and tightened with the nut.

Tightening should be performed in accordance with the requirements of the connection system used. Do not attempt to eliminate leaks by excessive pressure on damaged surfaces. Before starting the installation, it is necessary to check for leaks and confirm the permissible operating conditions of the complete connection.
