Garlock Sealing Technologies has a new metallic seal designed to meet the demanding requirements of the semiconductor, ultra-high vacuum, space and nuclear industries.
Garlock Sealing Technologies has introduced a new metallic seal designed to meet the demanding requirements of the semiconductor, ultra-high vacuum, space and nuclear industries.
A joint development with CEA, the French Atomic Energy Commission, the Ultra-Flex seal design achieves a high sealing tightness of 1x10-9 cm3/s He with clamping pressures equivalent to that of elastomeric seals.
Ultra-Flex has an open C cross-section manufactured from an exterior metal sealing material - gold, aluminium, silver or copper, depending on the application - formed over an internal metallic core of Inconel.
On loading the seal during assembly, two opposing offset ridges on the sealing face move into the optimum position as the C section deforms.
The metallic composition of Ultra-Flex provides benefits over elastomer seals including high and low temperature resistance, zero outgassing, reduced contamination and wider chemical resistance.
Ultra-Flex is available in a wide range of sizes and materials either from stock or manufactured to customer specifications.
