Working Principles

Understanding how our test point fittings work helps ensure proper selection, installation, and
maintenance for optimal performance.

working principle Test point Fitting

Test Port Fitting Operation

Hydraulic test ports are fittings that allow quick and easy connection of test instruments to a hydraulic system for pressure measurement, fluid sampling, or air bleeding. They facilitate diagnostics and maintenance by enabling convenient access to the system's fluid without needing to shut down the system or remove components.

Avoid Common Pitfalls

Even the best fittings can fail when improperly selected or installed. Learn how to avoid these common mistakes.

Incorrect Material Selection

The Issue
  • Choosing materials incompatible with the fluid or environment can cause rapid corrosion, contamination, or premature failure.
The Solution
  • Analyze your fluid properties and environmental conditions carefully. Consult our material compatibility chart or speak with our engineers for guidance.

Improper Installation Torque

The Issue
  • Over-tightening can damage threads, crush sealing components, or warp fitting bodies, while under-tightening leads to leaks.
The Solution
  • Always follow manufacturer torque specifications and use a calibrated torque wrench for critical applications

Mixing Thread Standards

The Issue
  • Attempting to connect incompatible thread types (NPT, BSPT, metric) can cause leaks or complete system failure.
The Solution
  • Verify thread specifications before installation and use appropriate adapters when transitioning between different thread standards.

Inadequate Support

The Issue
  • Unsupported pipes create stress on fittings, potentially causing leaks or complete separation, especially in systems with vibration.
The Solution
  • Install appropriate pipe supports and anchors according to engineering standards, particularly near direction changes.

FAQ

What is a hydraulic test fitting?

The hydraulic test fitting is designed to facilitate the connection of test instruments to the hydraulic system to detect and diagnose system problems, and also to reduce the risk of contamination.

What are the benfits of hydraulic test fittings?

Hydraulic test fittings prevent contamination from entering the system, do not require stopping the equipment to test the pressure, are simple to operate, and are resistant to high pressure. These advantages can relatively reduce costs and maintenance expenses.

What thread types are available for hydraulic test fittings?

Hydraulic test fittings are also available in a wide variety of thread types, including JIC, NPT, BSPP, Metric, UNF, and more.

What are the materials of hydraulic test fittings?

Hydraulic test fittings are normally made of metal, including stainless steel, steel, carbon steel, nickel-plated alloys and zinc, etc.

What are hydraulic test fittings used for?

Hydraulic test fittings are typically used to connect pressure gauges or hydraulic hoses for pressure testing, sampling, venting in hydraulic systems. These fittings can be applied in engineering, agriculture, and equipment testing industries, etc.

What types of hydraulic test fittings are available?

There are many different types of hydraulic test fittings, the common ones being adapters, couplers, couplings, caps, etc.

What is the maximum pressure that a hydraulic test fitting can withstand?

The maximum operating pressure that a hydraulic test fitting can withstand cannot exceed 63MPa, or 9000psi.

Is it necessary to set up a hydraulic pressure hydraulic test fitting?

Because hydraulic systems are designed to be more complicated and difficult to detect, the setting up of hydraulic hydraulic test fittings facilitates the detection of hydraulic system faults, as well as the release of some of the gas in the pipeline, reducing the chance of equipment damage and greatly improving the efficiency of the system. Therefore, it is very necessary to set up hydraulic testing port fittings.

Where to purchase hydraulic test fittings?

If you have a purchase request, you can click on our website to place an order, or inquire with our staff.

Can you get free sample of hydraulic test fittings?

Of Course, our company can provide free samples of hydraulic test fittings.
