4BN BSP Male Captive Seal Hollow Hex Hydraulic Plug

The 4BN BSP Male Captive Seal Hollow Hex Hydraulic Plug is a professional hydraulic component. Its core characteristics are:

（1）Thread specification: It adopts the BSP standard external thread, which forms the basis of its international universality and is divided into two types.

①BSPP (G): Parallel threads, the seal is entirely dependent on the end face integrated sealing ring.

②BSPT (R): Conical thread, capable of achieving inter-metallic sealing, but not compatible with BSPP.

（2）Anti-detachment Sealing: Core Design. The integrated sealing ring is fixed in the end face groove by a physical method, ensuring that the 4BN BSP Male Captive Seal Hollow Hex Hydraulic Plug will not move or come off even under high pressure and vibration. Common sealing materials include NBR (general oil-resistant type) or FKM (high-temperature resistant and chemical corrosion resistant type).

（3）Hexagon drive: Located at the head, it can be installed and disassembled using a standard hexagonal wrench, and is particularly suitable for operation in narrow or confined spaces.

（4）Sturdy body: The main body is usually made of durable materials such as carbon steel (high strength, often galvanized for rust prevention), stainless steel (high corrosion resistance), or brass (often used in water and gas lines), to withstand high pressure and harsh environments.

Technical Specifications

（1）Comply with the standard: The 4BN BSP Male Captive Seal Hollow Hex Hydraulic Plug complies with the ISO 1179-2 (Type E) international standard.

（2）Specification range: The thread sizes typically range from G1/8" to G3".

（3）Work pressure: The pressure level varies depending on the specification of the 4BN BSP Male Captive Seal Hollow Hex Hydraulic Plug.

（4）Operating temperature: Varies depending on the material of the sealing ring, and the range is quite wide.

（5）Size parameters: The overall dimensions will vary depending on the thread specification. The core dimensions include the diameter of the head, the total length, and the width between the opposite sides, etc.

（6）Surface treatment: To enhance corrosion resistance, the surface will undergo treatments such as galvanizing and nickel plating.
