Squeezing Salvages Oversize Seals

Thermal and mechanical properties of seal material used to advantage. Simple sizing tool compresses polychlorotrifluoroethylene seal to smaller diameter. Polymer seal held by aluminum rings, then compressed by differential thermal expansion between seal and rings. Inner diameter of seal reduced by small amount sufficient to enable remachining to specified size.
