Our YOUQI DHS PU dust wiper seals are manufactured from premium‑grade PU (TPU/PUR) polyurethane, delivering outstanding wear‑resistance and anti‑dust performance for hydraulic and pneumatic cylinder systems. Designed for piston and rod sealing, these seals work reliably against hydraulic oil, liquid and gaseous media under diverse operating conditions.

We supply standard dimension YX45×53×10, alongside fully custom non‑standard sizes to match unique equipment requirements. Colors include blue and green, and custom color options are available upon request. Suitable for rotary and reciprocating motion scenarios, DHS dust seals effectively block external dust, dirt and debris from entering cylinder interiors, preventing component abrasion and extending service life.

Strict quality control is implemented throughout production. Both standard and non‑standard specifications are supported. Sourced from Shanghai, China, our seals serve industrial fluid‑power clients worldwide with stable, cost‑effective sealing solutions.
