Product Description

Asymmetric Hydraulic Rod Seal PU Oil Seals RU3 D-3

 

The JB-3 is a single-acting hydraulic rod seal with asymmetric profile. The JB3 U-ring features precision-angle-trimmed sealing lips, providing optimum sealing efficiency for light, medium and heavy duty applications. It can be easily configured with a compatible full-depth back-up ring to withstand extreme pressure spikes in harsh environments.

The inner dynamic lip is asymmetrically designed with an advanced profile, intentionally shorter and more robust than a symmetrical U-ring, greatly improving the sealing and the compression set properties.   We also provide u-cup seals for low-temperature applications.
