PTFE Spring Energized Seals

SPRING ENERGIZED SEAL FEATURES AND BENEFITS

Wide range of temperature and pressure with almost unlimited chemical compatibility

Standard seals can be used at pressures up to 3,000 psi.  Custom seals up to 60,000 psi

Standard seals can operate in the range of –280 to 500oF

Custom designs can operate in the range of –400 to 600oF

Low friction and long service life

Wide range of PTFE compounds available

Can be used for rotary, reciprocating and oscillatory motions.

HOW THE SPRING ENERGIZED PTFE SEALS WORK

The MSE seal is a sealing device consisting of a PTFE or other polymer, energized by a corrosion resistant metal spring.  When the seal is seated in the gland, the spring is under compression applying force on the gland sealing surfaces thereby creating a tight barrier to prevent gas or fluids from leaking.  The spring also provides resiliency to compensate for seal wear, gland misalignment or eccentricity.  While spring force provides adequate force for sealing at low pressure, at high pressure the system pressure augments the spring force to provide an even tighter seal.  The MSE seals are precision machined from PTFE, filled PTFE and other high performance polymers.
