Metal Spring‑Energized MSE®

Metal Spring‑Energized (MSE®) Seals deliver reliable, high‑performance sealing for demanding applications across a wide range of pressures, temperatures, and media. Designed for versatility and durability, MSE seals use a precision‑engineered metal spring to maintain constant load and compensate for hardware misalignment, wear, and thermal expansion.
Available in diameters from 0.110 in. (0.279 cm) to 60 in. (152.4 cm), MSE seals can be customized for diverse application needs. Multiple seal geometries and energizer styles allow optimized performance in dynamic or static environments, including high‑pressure, high‑vacuum, cryogenic, and chemically aggressive conditions.

Product Options Include:

Finger Spring Energized MSEs
Coil Spring Energized MSEs
Canted Coil Spring Energized MSEs

Material Choices:

Jacket Materials: Multiple grades of Avalon® PTFE, engineered for chemical resistance, low friction, and long service life.
Spring Materials: Options include Stainless Steel, Elgiloy®, and Inconel®, selected for strength, corrosion resistance, and high-temperature stability.

Engineered for precision and reliability, MSE seals offer a robust sealing solution for industries such as aerospace, semiconductor, energy, chemical processing, and industrial equipment.
