Hydraulic Pressure Test Coupling

Our hydraulic pressure test coupling (also known as hydraulic test point) is a high-precision fluid connection component designed for hydraulic systems. It provides a safe, convenient and reliable way to connect pressure gauges, test instruments or diagnostic tools to hydraulic pipelines, enabling real-time pressure monitoring, system debugging, fault diagnosis and routine maintenance. With a compact structure, excellent sealing performance and wide compatibility, it is an essential accessory for all types of industrial hydraulic systems, from construction machinery to industrial hydraulic stations.

Key Features

1. Zero Leakage & High Pressure Resistance: Adopts advanced sealing structure and high-precision machining, ensuring zero leakage during pressure testing. With high pressure rating (up to 60MPa/8700PSI), it is suitable for high-pressure hydraulic systems, with excellent impact resistance and long service life.

2. Quick Connect & Self-Locking Design: The quick-plug structure enables fast connection and disconnection without tools, improving work efficiency. The built-in self-locking mechanism ensures a secure connection, preventing accidental disconnection during testing, ensuring operational safety.

3. Anti-Contamination Protection: The integrated check valve design prevents hydraulic oil leakage and external dust, impurities from entering the hydraulic system during connection and disconnection, avoiding system contamination and protecting core hydraulic components.

4. Robust & Durable Construction: Made of high-quality carbon steel or stainless steel, with surface zinc plating or nickel plating treatment, it has excellent corrosion resistance, wear resistance and rust resistance, suitable for harsh industrial environments such as high temperature, dust and humidity.

5. Wide Compatibility & Customization: Supports a variety of standard thread specifications (such as G1/4, G1/8, M10×1, M12×1.5, NPT, etc.) and connection types, compatible with most hydraulic systems and pressure gauges. Customized specifications are available to meet special application requirements.

6. Easy Installation & Maintenance: Compact size, simple installation, no need for complex tools. Regular inspection of the sealing ring is sufficient to ensure long-term stable performance, reducing maintenance costs.

7. Safety & Reliability: Complies with international hydraulic industry standards, with strict factory pressure testing and quality inspection, ensuring stable and reliable performance in various working conditions.
