Metallic Seals

Metallic seals can be used to seal at temperatures outside the recommended operating range of elastomeric seals. Eaton can make a seal from almost any alloy that can be formed. In high-volume applications and when using newly developed alloys, the cost of the alloy is a factor to consider. Overwhelmingly, however, strength (spring) properties are the primary technical consideration. The more severe the application, the more important it is to use strong, resilient materials. Iconel 718 is Eaton’s first choice of material when strength and resiliency are concerns. Inconel 718 offers the best engineering properties for sealing within its operating temperature range.
