BSP Plug (AGR) 1/8" with hex socket 14

The BSP (AGR) 1/8" plug with hex socket 14 is a steel blanking element designed to close compatible connections with an internal thread. It features a 1/8" cylindrical BSP male thread and a 60° internal sealing cone. Its straight design, equipped with a socket for a wrench, allows for installation and removal with a correctly selected tool.

The product belongs to the 34.75 type hydraulic connector group, referred to in English documentation as Male Plug - Thread BSP Parallel. It is made of steel with galvanic surface protection. The plug is used to seal appropriately matched hydraulic system ends where closing a connection with a BSP internal thread is required.

Technical parameters of the BSP AGR 1/8" plug

Product type: hydraulic blanking plug.
Connection type: AGR.
Thread size: BSP 1/8".
Thread type: external, cylindrical BSP.
Seal type: 60° internal cone.
Construction type: closing nipple.
Shape: straight.
Execution: with hex socket.
Designation in product name: 14.
Material: steel.
Surface protection: galvanized.
Product symbol: 4B-02.
Designation according to Rastelli-Raccordi: 34.75.00.02.
Designation according to Cast: 307801.
Catalog type: 34.75.
English name: Male Plug - Thread BSP Parallel.
Purpose: blanking compatible connections with internal threads.

Application of the BSP AGR 1/8" plug in power hydraulics

The BSP AGR 1/8" plug is used to close ends equipped with a correctly selected BSP internal thread. It can be used during the assembly of hydraulic systems, component replacement, maintenance work, and blanking of unused connections.

The design with an external thread allows the plug to be fixed in a compatible threaded hole. Before application, compatibility of the thread and the sealing method of the mating connection must be checked. The thread size alone is not sufficient confirmation of compatibility.

External BSP 1/8" cylindrical thread

The plug is equipped with a cylindrical BSP male thread in size 1/8". It is designed to work with a corresponding connection having an internal thread. The cylindrical execution of the thread is an important identification feature of this variant.

During selection, distinguish the cylindrical BSP thread from tapered threads and other connection systems. The design of the sealing surfaces should also be considered, as thread compatibility does not guarantee the tightness of every connection.

60° internal cone – sealing type

The BSP AGR plug has an internal conical surface with a 60° angle. This solution is designed to work with a correctly matched hydraulic connection element. Proper tightness depends on the compatibility of the sealing surface geometry and correct installation.

Before installing the plug, check the condition of the conical surface and the mating element. Scratches, deformations, and contamination can affect the tightness of the connection. Do not assume that tightening the thread alone will provide a proper seal.

Hex socket – installation and removal of the plug

The BSP (AGR) 1/8" plug is equipped with a hex socket, which allows for its installation and removal using a correctly selected tool. In the name of this variant, there is an additional designation 14.

During installation, check the condition of the socket, thread, and mating surfaces. The tool should be properly fitted to reduce the risk of damaging the element during tightening or loosening.

Steel construction and galvanic surface protection

The BSP AGR 1/8" plug is made of steel. The surface of the product has been galvanically protected, which provides protection for the steel element against corrosion.

Before applying the product, consider the system requirements regarding material, operating environment, and working parameters of the complete connection. Proper selection should include both the plug design and the system's operating conditions.

Catalog designations 4B-02, Rastelli-Raccordi, and Cast

The BSP AGR 1/8" plug can be identified based on the 4B-02 symbol and catalog designations used by hydraulic fittings manufacturers. According to Rastelli-Raccordi, the product has the designation 34.75.00.02, while according to Cast, it appears under the number 307801.

These designations facilitate searching for the correct variant when assembling hydraulic systems and selecting spare parts. When comparing elements, check the compatibility of thread size, design, and sealing surface type.

Catalog type 34.75 – Male Plug BSP Parallel

The plug belongs to the 34.75 type connector group. The English name Male Plug - Thread BSP Parallel means a plug with an external cylindrical BSP thread. The product has a simple closing nipple design and a 60° internal conical surface.

When choosing an element, pay attention to the compatibility of all design features with the hydraulic connection. Threaded plugs can come in various versions, so they should not be selected solely based on thread diameter.

Selecting the BSP AGR 1/8" plug for a hydraulic connection

Before purchasing, verify the internal thread of the mating connection and its sealing design. For this variant, the external 1/8" BSP thread, the cylindrical character of the thread, and the 60° internal cone are essential.

When replacing a previously used plug, the designations 4B-02, 34.75.00.02, and 307801 are helpful. Before using a replacement element, confirm its compatibility with the requirements of the specific connection.

Installation and leak test of the BSP AGR plug

Before installation, turn off the device and safely depressurize the hydraulic system. Then, clean the plug thread, connection, and sealing surfaces. Do not install elements with damaged threads or mating surfaces.

The plug should be fixed in the appropriate connection and tightened with a tool matched to the hex socket, according to the requirements of the connection system used. After completing the installation, check the correctness of the fixing and the tightness of the connection before starting the system.
