Double Wiper

The double wiper seal meets current U.S. environmental regulations and is commonly used on riveted above ground tanks where shoe seals are not the most effective, and on internally coated tanks where a shoe seal could abrade the coating.  Available in several elastomeric and foamed materials, these seals typically have limited product compatibility and temperature ranges.
