How Do UN Seals Eliminate Hydraulic Downtime

Seals play a crucial role in hydraulic systems. U-shaped seals made of polyurethane (PU) and fluororubber (FKM) perform particularly well in high-intensity environments, such as those found in construction machinery, motors, and industrial robots.

Why choose polyurethane (PU) and fluororubber (FKM)?

Polyurethane is known in the industry as the "fifth plastic" because it combines the properties of both plastic and rubber. Honestly, traditional rubber often quickly breaks down in acidic and alkaline environments or when exposed to organic solvents, while PU offers far greater resistance. Its elasticity and toughness prevent deformation and aging even after extended use, ensuring a stable seal. Fluororubber is highly chemically stable, offering resistance to high temperatures, oils, high vacuum, acids, alkalis, and a variety of chemicals. It also boasts relatively good media resistance among elastomers.

NQKSF is U-shaped piston seal series, designed specifically for hydraulic systems, can withstand temperature fluctuations from -20°C to 250°C, making it suitable for a variety of complex environments. More importantly, as oil pressure increases, its sealing force automatically strengthens, significantly reducing leakage.

Application Scenarios and Industry Demands

Speaking of their applications, U-shaped piston seals are used across a wide range of industries. Industrial machinery, especially pumps and hydraulic cylinders, places stringent demands on seals. Seals in motors, gearboxes, and engines also require both high-pressure and wear resistance. Agricultural and construction machinery often operate in harsh environments, making U-shaped seals' corrosion resistance and compression resistance an excellent choice.

Of course, industries like water treatment, wind power generation, and the chemical industry also place extremely high demands on seal stability and durability. NQKSF has accumulated extensive experience in the sealing field over many years, exporting its products to over 80 countries and earning widespread recognition.
