(Prefix)(CS) - (Inside Dia) - (Height)
Standard - Height and cross section are equal, thus giving a square seal. Utilizes type 'D' lip. Typical Part Number U25-2.50
Deep - Utilizes the same 'D' lip, but the seal height is greater than the cross section, thus giving a rectangular shape. Typical Part Number U25-2.50-37D
Type SQB - Same dimensions as the Standard seal. Beveled lip design provides better film breaking. Utilizes type 'B' lip. Typical Part Number U25-2.50-SQB
Type B - Same dimensions as the Deep seal. Beveled lip design provides better film breaking. Utilizes type 'B' lip. Typical Part Number U25-2.50-37B
