VS-RS20B2

Double-Lip V-Spring-loaded rotary shaft seal for extreme environments

This seal is designed to provide long service life and low friction for extreme service applications over a wide temperature range. This seal is for high PV applications characterized by high pressure and low speed. This seal has a small axial length, and is available in many materials specially suited to handle aggressive chemicals and environments. A secondary dust lip provides dirt exclusion and retains fluid. Also available in small quantities for repairs and seal replacement in 1 to 3 days.

VS-RS20HP

Ultrahigh pressure single-lip rotary shaft seal for extreme environments.

This seal is designed to provide long service life and low friction for extreme service applications over a wide temperature range.

This seal is for high PV applications characterized by high pressure and low speed. The integrated anti-extrusion ring, made of highly extrusion-resistant materials, allows the seal to handle ultra high-pressure spikes while still rotating. This seal has a relatively small footprint and is available in many materials specially suited to handle aggressive chemicals and environments. Also available in small quantities for repairs and seal replacement in 1 to 3 days.
