DSH Seals has kept pace with the industry standards which expand to meet safety requirements. The dust rubber seals/wiper seals/dust seals and other sorts of seals in DSH Seals meet environmental standards’ requirements and industrial conditions. The wiper seal, also likewise referred to wipers, scraper ring, rubber seal, is a piston ring. It is also called the wiper ring or rubber dust seal. The wiper seal is a scratch-resistant double lip rubber dust seal. Seals made of nitrile rubber and fluoroelastomer are all acceptable for a vast selection of
operating temperatures, preventing debris from entering, protecting equipment, and maintaining performance.

Dust seal, crucial in hydraulic equipment, shields the vital equipment components by removing the dust from the rod surface. By avoiding the infiltration of debris, particles, metallic chips, or weld flash which may affect or damage the operation of the valve and the pump function, it boosts the machines or devices to perform stably. The exterior static sealing of the wiper seal within the housing also plays a vital role in preventing moisture and particles from getting into the wiper seal. These seals also keep the lubricant from escaping the hydraulic system. Wiper seals contribute substantially to improving the uptime of the apparatus, as they prevent the contamination of the hydraulic fluid which can damage the wear rings and other components. The wiper seals additionally protect the piston rod on the film, which eventually leads to the lubrication effect of the seals. Wiper seal is designed to
scrape excess lubricating oil from the cylinder wall or hydraulic system to prevent excessive oil from penetrating the combustion chamber. The wiper seal is widely utilized in manufacturing and mechanical industries, such as crushing machines, pneumatic and hydraulic cylinders, steelworks, or chemical pumps. It may likewise be seen at the telescopic suspension forks of motorcycles and bicycles.

Seals fail commonly due to misuse or abuse use, deterioration, exposure to the inappropriate medium environment, and inability to rebound after being compressed, which may finally result in a
severe oil spill. DSH Seals had each of these factors under account before it developed a selection of exemplary
dust rubber seals. Our dust rubber seals have these features.

Characteristics:

The use of our wiper seals/dust seals in industrial applications can provide several
benefits:

1. Good anti-contamination performance. The seals keep the dirt or particles from
stepping into any part of the inner mechanical system.

2. Anti-leakage. It is successful in sealing up various medium liquids, so it helps
reduce the probabilities of any machine or device breaking down or collapsing.

3. Insensitive to shock loads and pressure peaks. The seals work efficiently even in
heavy load or other extreme working conditions.

4. Extreme temperature adaptability. Featuring excellent heat resistance, it works
normally and stably under high and cold temperatures.

5. Ease of installation and maintenance. An engineer can easily replace the wiper
seal in a few minutes.

6. Dimensional accuracy.

7. Wear-resistant. It can withstand heavy and busy use conditions without the problem
of wearing out, making it especially suitable for industrial use.
