Ultra Low Emissions with the FLEXSEAL® ULE

Garlock FLEXSEAL® ULE - Ultra Low EmissionsGarlock has expanded their Ultra Low Emissions family of products to include a spiral wound gasket. The FLEXSEAL® ULE is designed for use where leakage control is critical and the aggressive application requires a spiral wound design. It’s manufactured using high performance graphite, and offers maximum protection against oxidation. The standard design includes an inner ring and outer ring, as well as preformed metal wire to enhance compressibility and sealability. The FLEXSEAL® ULE spiral wound is another product born from Garlock’s customer driven innovation.
