MSE® Seal
Optimum Sealing Solutions
HIGH-PERFORMANCE, LOW-FRICTION SEAL
The MSE® (Metal Spring Energized) seal’s superior designed “dual-lip body” gives improved sealing performance. Because our expertise in custom design and fabrication leads innovative designs, special configurations of MSE seals are limitless.
Anti-Blowout MSE Seals
Greene, Tweed has developed a specially configured MSE Seal for applications where the dynamic sealing surface is withdrawn past the seal interface while the seal remains under pressure.
The seal and housing geometry allows the withdrawal/removal of the dynamic sealing surface without the seal being “blown” from its gland.
The seal is manufactured from Greene, Tweed’s proprietary grades of PTFE, creating extremely low-friction characteristics. Seals operate at pressures to 6,000 psi (414 bar); however, higher pressures can be achieved.
The seals unique design gives secure sealing over repeated demanding applications.
