This results in equipment that runs smoothly with longer seal life. ■ Sizes up to 70 inches (1778 mm ) are available in 95A Super Polymer through our fusion program. ■ 95A Super Polymer is recognized as the best overall seal material that can be used in the majority of situations. Other materials available to meet specific requirements. 10K Standard Available Materials & Seal Sizes Materials Code H S 95A Super Polymer* O ≤1.50 ( 38 ) ≤1.25 ( 32 ) 85A Super Polymer A ≤1.50 ( 38 ) ≤1.25 ( 32 ) Fluoroelastomer J ≤0.75 (19 ) ≤0.75 (19 ) Hi-Temp.
