✅ Core features of hydraulic hose connectors:

1. High pressure resistance

Hydraulic connectors are usually used with high-pressure steel wire braided hoses and can withstand pressures of 10~60 MPa (100~600 bar) or even higher. Compact structure, secure locking, not easy to leak or fall off.

2. Strong sealing performance

Multiple sealing structures are often used, such as O-ring seals, cone seals, spherical seals, etc., to ensure long-term leakage-free operation under vibration, high pressure or temperature fluctuations.

3. Various connection methods

Common connection forms include:

Compression fittings (DIN ferrules): commonly used for small and medium-caliber metal pipe connections;

Internal/external thread connectors: suitable for hose or valve body interfaces;

Flange connection: used for large diameter, high pressure or frequent disassembly;

Quick couplings (Quick Coupling): realize quick connection and disconnection without tools, commonly used in mobile equipment or inspection stations.

4. High material strength

Mainly made of carbon steel (galvanized surface), stainless steel (such as 316), brass and other materials, with excellent strength, pressure resistance and certain corrosion resistance. Stainless steel connectors are preferred in chemical or marine environments.

5. End structure is suitable for various hoses

The design of the end of the connector can be crimped or plugged with the hose, divided into:

Crimp type with compression sleeve (need to be pressed with hydraulic pipe crimping machine);

Plug-in type with barb (suitable for low-pressure hose);

Embedded type with guard ring (suitable for multi-layer steel wire braided hose).

? Common connector standards and models:

BSP (British thread)

NPT (American taper pipe thread)

DIN 2353 ferrule series

JIC 37° cone seal (SAE standard)

ORFS flat seal

ISO 6162 flange connector (high-pressure flange)

Metric (metric thread), etc.

? Application scenarios:

Connection between hydraulic system hose and cylinder, valve group, pump station;

Engineering machinery, agricultural machinery, mining equipment hydraulic pipeline;

Injection molding machine, CNC machine tool, die-casting equipment hydraulic system;

Switching, testing or emergency connectors in mobile equipment;

High-pressure hydraulic equipment in heavy industries such as ships, wind power, and steel mills.
