WEU Series Triple-Function Rod Seals | Sealing, Dustproof & Retention Solutions for Pneumatic Cylinders
Engineered for precision pneumatic systems, the WEU Series Piston Rod Seal uniquely integrates sealing, dust exclusion, and axial retention in a single compact unit. Crafted from 90 Shore TPU, this specialized seal excels in low-pressure applications (≤1.6 MPa) while withstanding -35°C to +80°C temperature extremes—ideal for automated machinery and pneumatic actuators.
