● Strong Pressure Resistance: The fittings are meticulously designed to withstand high pressure, ensuring the stable transfer of fluid during the operation of the hydraulic system. They are less prone to rupture or leakage, guaranteeing the safe and efficient operation of the system.
● Durable Materials: Usually made of high-quality materials such as stainless steel and brass, they possess excellent corrosion resistance. Even when in contact with various working media for a long time, they can maintain their structural integrity and extend their service life.
● Reliable Sealing: Paired with superior sealing materials like nitrile rubber and polytetrafluoroethylene, they can effectively prevent liquid leakage, ensuring the sealing performance of the hydraulic system and avoiding pressure loss and environmental pollution caused by leakage.
● Easy Installation: Generally, they have a compact and reasonable design with small dimensions, facilitating installation operations in narrow spaces. They can flexibly adapt to a variety of complex equipment layouts, saving installation time and labor costs.
● Wide Compatibility: They are suitable for many different types of hydraulic oils and working media. Whether it is common mineral oil or special antifreeze, ethylene glycol, etc., they can be well adapted to meet diverse industrial application requirements.

Factors |
Specific Performance |
|
Material Properties |
Stainless steel, rich in alloy elements like chromium and nickel, forms a dense passive film to resist corrosion from air, water and other media, ensuring a long service life in humid, acidic and alkaline environments. |
|
Sealing Design |
Equipped with nitrile rubber seals, whose molecular structure is tight and has a high barrier property against working media like oils, preventing media intrusion and corrosion of internal parts to ensure long-term normal use of the fittings. |
|
Manufacturing Process |
Precision forging process makes the overall structure of the fittings dense and uniform without internal defects, reducing the occurrence of cracks and deformation when under pressure and external impact, thus enhancing durability. |
|
Operating Environment |
In a suitable indoor industrial environment with a temperature of 20 - 25°C, the material properties of the fittings are stable, and the aging speed of each component is slow, enabling normal use for several years. |
● Regular Tightening Checks: Ensure all connecting parts are securely tightened to prevent leaks.
● Hydraulic Oil Replacement: Replace hydraulic oil regularly to maintain cleanliness and avoid contamination and aging.
● Cleaning and Maintenance: Regularly clean the pump body and fittings to remove dust and oil stains, keeping the equipment tidy.
● Valve Seal Inspection: Check the sealing performance of valves and replace damaged seals promptly to prevent leaks.
● Proper Storage: Store in a dry and well-ventilated area when not in use to avoid damage from harsh environments.
