MSE® SEALS SEALING SOLUTIONS Greene, Tweed's MSE® seal consists of a sealing device made from a PTFE or other polymeric component, energized by a corrosion- resistant metal spring or an elastomeric O-ring. When the seal is seated in the gland, the spring is under compression, applying force on the gland sealing surfaces and, thereby, creating a tight barrier to prevent gas or fluid from leaking. The spring also offers 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. MSE seals are precision machined from PTFE, filled PTFE and other high-performance polymers. Greene, Tweed's design experts partner with customers when choosing from over 100 seal materials, a variety of spring materials and three standard spring designs. Their expertise ensures that our customers select the best combination of materials and design to meet and exceed their application requirements.
