How do you stop a hydraulic pipe fittings from leaking?

Why do hydraulic pipe fittings leak? 

1. Uneven or damaged sealing surfaces: Damaged, worn, or uneven sealing surfaces can cause the seal failure of the hydraulic fittings, causing leaks. 

2.Improper installation: hydraulic pipe fittings can also lead to leakage if they are not installed in the correct way and specifications. For example, insufficient tightening strength, improper gasket installation, etc.

3.Loose or damaged fitting parts: Parts in hydraulic pipe fittings, such as screws, spring plates, etc., can also cause leaks if they are loose or damaged. 

4.High hydraulic oil temperature: Excessive hydraulic oil temperature can cause seals to age, harden, and fail, which in turn can cause leaks. 

5.Excessive or overloaded hydraulic pressure: Pressures and loads that exceed the range of the hydraulic pipe fittings can also cause leakage in the hydraulic pipe fittings. 

To sum up, hydraulic pipe fittings leakage is caused by a variety of factors, in order to avoid the occurrence of such situations, it is necessary to pay attention to reasonable installation, regular inspection and maintenance, and choose hydraulic pipe fittings products that are suitable for working conditions and loads. 

What are the hazards of hydraulic pipe fittings leakage to equipment? 

1.Reduce work efficiency: Leakage will lead to a drop in pressure and flow in the hydraulic system, which will reduce work efficiency and increase production costs. 

2.Damage to the equipment: Leakage can cause corrosion of parts and materials around the equipment, which can lead to damage to the equipment. 

3.Increased maintenance costs: If the leakage problem is not dealt with in time, it will lead to greater damage and increase the repair cost. 

4.Environmental pollution: Leakage will cause hydraulic oil to leak into the environment, pollute the environment and cause harm to the ecosystem. 

5.Safety issues: Oil leakage will make the ground slippery and increase the incidence of accidents. Especially for flammable and explosive hydraulic fluids, it can also cause fire or explosion. 

To sum up, leakage of hydraulic pipe fittingss may cause serious harm to the equipment, so measures should be taken to repair the leakage as soon as possible, and pay attention to the maintenance and maintenance of the hydraulic system to ensure the safety and normal operation of the equipment. 

How to prevent leakage?


In order to prevent leakage of hydraulic pipe fittingss, we can take the following measures: 

1.Choose high-quality hydraulic fitting products: Make sure that the specifications and models of hydraulic pipe fittingss meet the needs of the actual application and can withstand the required pressure and temperature range. High-quality hydraulic fittings ensure sealing performance and durability and reduce the incidence of leaks. 2. Correct installation and use: When installing the hydraulic pipe fittings, it is necessary to ensure that the sealing surface is clean, smooth, free of impurities and wear. At the same time, it is necessary to ensure the correct installation speed and channel, as well as parameters such as torque, and use the correct seals. 

2.Regular inspection and maintenance: Regularly check the operation status of the hydraulic system and hydraulic pipe fittingss, deal with problems in time, and replace aging seals. 

3.Control pressure and load: For hydraulic pipe fittingss, the pressure and load should be controlled within a reasonable range to avoid excessive or overload. 

4.Environmental protection: The environment of the hydraulic system should be kept dry and clean to avoid impurities such as dust and moisture from entering the system and affecting the sealing performance of the hydraulic pipe fittings. 


In summary, preventing leakage from hydraulic pipe fittingss requires a multi-faceted approach, including measures such as selecting quality products, proper installation and use, regular inspection and maintenance, controlling pressure and load, and environmental protection. Only by fully implementing these measures can the safe and stable operation of hydraulic pipe fittingss be guaranteed.

Which products have better sealing performance? 

Metric compression type hydraulicpipe fitting is a common hydraulic pipe fitting product, which adopts the compression type sealing structure, which can achieve a better leakage prevention effect. It has the following advantages: 

1.Good sealing performance: The compression structure can realize the double sealing of static seal and dynamic seal, which can ensure the sealing performance of the hydraulic system. 

2.Strong bearing capacity: The ferrule in the ferrule structure can withstand large pressure and load, which can ensure the safety and reliability of the hydraulic pipe fitting under high pressure and high load conditions. 

3.Easy installation: The ferrule structure has the characteristics of plugging and reusing, which can be easily disassembled and replaced, and is suitable for working occasions that need to be replaced frequently. 

4.Low maintenance cost: The compression type sealing structure can be compatible with the general hydraulic pipe fitting threaded interface, and its maintenance cost is relatively low, and the use cost has obvious advantages.

To sum up, the leakage prevention effect of metric compression hydraulic pipe fittings is relatively good, and it is suitable for working occasions that require high requirements for working environments and high loads, but it is still necessary to pay attention to maintenance during use and replace aging seals in time to ensure their long-term stability and safety.
