Product Introduction
We attach great importance to brand building, unique market positioning and scientific marketing and promotion, which makes our oil seal double lip, step rod seal, SPNS seals stand out. Credibility is our flame, hot and bright, intoxicating. But if you don't add firewood and coal and persevere, the flame will go out. Although our company has achieved remarkable results, our company still insists on improving from all aspects and keeping up with the trend of the times.
Description
Piston Step Seals DSD is composed of PTFE seal and O-ring. A single-acting O-Ring energized piston seal for dynamic applications installed in closed grooves, including grooves to ISO 7425. Hydraulic step seals offers high sealing efficiency, low friction with no stick-slip, minimal break out force and high wear resistance.
Its design eliminates the potential for stick-slip and its very low running friction makes it ideal for high-speed applications. Provide outstanding wear and extrusion-resistance properties as well as large range of temperature and high-speed capabilities.
Piston Stepseal is available in a variety of DSH Seals high-performance materials to suit a wide range of demanding applications. A tandem arrangement using the DSD in an high performance material is effective in sealing high-frequency and long-stroke applications.
