MSE® Seals

Scraper Lip

Aerospace, Defense, Energy, Industrial Operations, Life Sciences, Semiconductor

The MSE® seal’s superior designed dual-lip body offers improved sealing performance in virtually unlimited media service and the widest temperature range. Finger Seal MSE® seals use a cantilever-type stainless steel spring to act as an energizer during low pressure situations. The spring compensates for seal wear in dynamic applications as well as overcoming the nonresilient nature of PTFE materials.

The scraper lip design is best suited for nonlubricated applications where abrasive media are present and space is limited. The scraper lip keeps abrasive media from getting between the seal and the hardware, thus decreasing abrasion. Available in rod and piston designs. Applicable to both static and dynamic applications.
