MSE® Seals

Coil Spring MSE® Face Seal

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.

MSE® internal and external pressure face seals are intended for static applications. Pressure operation is higher for face seals as the design assumes that the hardware clearance gap is reduced compared to standard clearances or assumes no clearance gap.

Features & Benefits

Coil Spring MSE® seals consist of a PTFE seal jacket energized by a high-loading coil spring and are intended for temperatures from -270°F to 550°F (-168°C to 288°C). These seals are mainly designed for static applications but will also work under dynamic conditions with surface speeds up to 100 ft/min

– Low friction
– Precise and uniform movement without stick/slip
– Low power absorption and torque requirements
– Friction can be adjusted and controlled
– Can run dry or lubricated giving a long service life Able to withstand corrosive environments
– Virtually unlimited media service with one seal
– Will not contaminate sensitive media Wide temperature performance envelope
