✅ Core features of hydraulic quick connectors:

1. No tools required, quick connection/disconnection

Operators can complete connection and disassembly in a few seconds without tools such as wrenches, which greatly improves on-site maintenance efficiency and replacement speed, and is suitable for frequent equipment switching or modular operation scenarios.

2. Self-sealing design, no leakage when disconnected

The connector usually has an automatic valve core or check device inside. When disconnected, both ends automatically close to prevent hydraulic oil leakage, contamination or system pressure loss, which is a key function for environmental and system pressure protection.

3. Reliable sealing and strong pressure bearing capacity

High-quality hydraulic quick connectors use a double-layer O-ring + conical or spherical sealing structure, which can withstand working pressures up to 2545 MPa (250450 bar) and maintain stable sealing without leakage under high pressure.

4. Multiple connection methods

Common connection end forms include:

External thread, internal thread (BSP, NPT, Metric)

Flange connection

Tube type (with clamp/ferrule)

Can be adapted to various hydraulic hoses, rigid pipes or system ports.

? Application areas:

Construction machinery: excavator attachments (breakers, wood grabbers), quick-change devices;

Agricultural equipment: tractors, combine harvester hydraulic pipelines;

Hydraulic testing: high-frequency connections in test stations or system debugging;

Petroleum, mining, metallurgical equipment: frequent disassembly and assembly, strong vibration equipment;

Wind power, ships: modular high-pressure fluid systems;

Industrial automation: robot hydraulic actuator quick connection;

⚠️ Notes:

When matching and selecting, pay attention to the pressure level, material, and sealing ring material (such as NBR, FKM, EPDM) of the male and female heads;

Different brands/models may not be compatible, and it is recommended to select a set;

It is recommended to release the system pressure during plugging and unplugging to avoid impact or oil splashing;

Flat quick connections are more suitable for occasions with high environmental protection requirements to prevent hydraulic oil residue from contaminating the ground or equipment.
