Description Small Size, Maximum Suction. The Grabo HighFlow Oval Foam Seal 80mm × 160mm for the GRABO HIGH FLOW achieves grip on small sizes and shapes of bricks, pavers, and stones. Use this seal on small materials where all other seals are too large to grip. This specialty seal features our new open-cell foam, which allows our high-flow to pull a maximum amount of air without creating a vacuum.
