Single-Lip V-Spring-loaded rotary shaft seal for extreme environments_VS-RS19B

VS-RS19B


Single-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 cross section 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.
