Reusable Hydraulic Fittings Pressure Rating Guide

Welcome to this comprehensive guide on hydraulic pressure ratings and reusable fittings. As professionals in the hydraulic industry, understanding the intricacies of pressure ratings and the types of reusable fittings available is crucial. This guide aims to provide you with in-depth knowledge, from the basics of pressure ratings to the cost-effectiveness of reusable fittings.

What is Rated Hydraulic Pressure?

Definition and Units of Measurement

In the field of hydraulics, the term “rated pressure” is of vital importance. It refers to the maximum pressure that a hydraulic component can safely withstand. The unit of measurement for pressure is usually pounds per square inch (PSI) or bar. For example, if a hydraulic hose has a pressure rating of 3000 PSI, it means the hose can safely withstand 3000 PSI without failure.

The Importance of Pressure Ratings in Hydraulic Applications

Understanding pressure ratings is not just a technical detail, it’s a safety issue. Imagine you are operating a hydraulic system that controls heavy machinery. If the system components can’t handle the pressure they’re being subjected to, they’ll fail. This failure is more than just a minor inconvenience; it can lead to catastrophic consequences, including equipment damage and even injury.

Why Pressure Ratings Should Not Be Ignored

Ignoring pressure ratings is dangerous behavior. The failure of one component in a hydraulic system can have a domino effect, causing other components to fail as well. This can lead to downtime, costly repairs, and, in the worst case, a serious safety incident.

The Role of Pressure Ratings in System Efficiency

In addition to safety, pressure ratings have an impact on the efficiency of a hydraulic system. Components with appropriate pressure ratings ensure that the system operates smoothly, without the risk of pressure drops or fluid leaks. This efficiency translates into better performance and, ultimately, cost savings.

Testing provides real-world data that can validate or challenge the manufacturer’s specifications. It’s an extra layer of assurance for the safety and efficiency of your hydraulic system.

Burst Pressure Test

One of the most common tests is the burst pressure test. In this method, fluid is pumped into the fitting until it reaches the point of failure, also known as the burst pressure. This test gives you an idea of the maximum pressure the fitting can withstand. However, it’s important to note that the burst pressure is not the same as the working pressure, which is usually much lower.

Impulse Test

The impulse test subjects the fitting to rapidly fluctuating pressures to simulate real-world conditions. This test is particularly useful for fittings that will be used in systems with varying pressure levels. The fitting is considered to pass if it can withstand a set number of cycles without failure.

Proof Test

impulse test machine Topa

In a proof test, the fitting is subjected to a specific pressure level for a predetermined period. If the fitting shows no signs of leakage or failure during this time, it is considered to have passed the test.

Vacuum Test

Some hydraulic systems operate under vacuum conditions. In such cases, a vacuum test can be conducted to ensure that the fitting can maintain its integrity under negative pressure.

Environmental Testing

Since environmental factors like temperature and corrosion can affect a fitting’s pressure rating, some tests incorporate these elements. For example, a fitting might be subjected to high temperatures or corrosive fluids to see how it performs under such conditions.

Safety Precautions

Always conduct these tests in a controlled environment and under expert supervision. Incorrect testing can not only provide inaccurate data but also pose safety risks.


After testing, it’s crucial to document the results meticulously. This documentation serves as a record that can be referred to in the future for maintenance or in case of system failure.
