Features
The hydraulic pressure gauge adapter is a handy component that simplifies the installation and connection of pressure gauges within your hydraulic system. It boasts several key features:
Versatile Interface: This adapter features 3/8"-18 National Pipe Thread (NPT) threads on both the male and female ends. This ensures secure and leak-proof connections to various components within your hydraulic system. Additionally, the threads for the pressure gauge interface can be customized to match your specific pressure gauge requirements, providing exceptional versatility.
Bearing Pressure: This robust adapter can withstand a bearing pressure of up to 70 MPa (megapascals), which is approximately 10,152 psi (pounds per square inch). This makes it suitable for various high-pressure hydraulic applications.
Simplified Installation: The adapter's threaded connections allow for easy installation into existing hydraulic lines. The male end screws directly into the pump or hydraulic cylinder port, while the female end connects to the hose or joint. The third threaded hole serves as a dedicated connection point for your pressure gauge.
Leak-Proof Connections: The threaded connections ensure secure and leak-proof integration within your hydraulic system, minimizing the risk of pressure loss or contamination.
Durable Construction: Manufactured from high-quality materials, typically stainless steel or brass, this adapter is built to withstand the demanding conditions of high-pressure hydraulic systems.
The adapter simplifies the process of adding a pressure gauge to your hydraulic system. Here's how it works:
1.Installation: The male end of the fitting is screwed into the port of the pump or hydraulic cylinder. This creates a secure connection.
2.Connection to Hose or Joint: The female end of the adapter is connected to a hose or joint. This allows for the flow of hydraulic fluid through the adapter.
3.Pressure Gauge Attachment: The third threaded hole on the adapter, typically located on the side, provides a connection point for the pressure gauge. This allows you to monitor the pressure within the hydraulic system.
By using a hydraulic oil gauge adapter, you can easily add a pressure gauge to your hydraulic system without affecting the existing connections. This makes it simple to monitor the system's pressure and diagnose any potential problems.
Conclusion: A Practical Solution for Pressure Monitoring
The hydraulic pressure gauge adapter is a practical and versatile solution for simplifying pressure gauge installation within your hydraulic systems. It offers ease of use, leak-proof connections, and compatibility with various hydraulic systems and pressure gauges. By incorporating this adapter, you can ensure effective pressure monitoring throughout your hydraulic equipment.
