Standard 12" × 12" (300mm) Replacement Vacuum Gasket for GRABO HIGH FLOW Lifters

The GRABO HIGH FLOW Foam Seal 300 is the direct OEM replacement gasket engineered for the GRABO HIGH FLOW 300mm suction plate. Designed for hardscape contractors, landscapers, and masons handling rough materials daily, this 12" × 12" uncut closed-cell foam pad clips firmly into place in seconds—instantly restoring factory vacuum seal performance on porous and semi-porous surfaces.

Because abrasive concrete pavers, cleft flagstone, and unpolished slabs wear down foam over time, micro-tears and compressed edges can silently degrade lifting capacity long before catastrophic seal blowout occurs. Rated to support up to 150 lbs (68 kg), keeping fresh FS300 seals on hand guarantees uninterrupted job-site uptime, reliable suction integrity, and consistent holding power shift after shift.

*Note: GRABO vacuum lifter tools and 300mm suction plates are sold separately.

  • OEM Replacement Specification: Factory-standard replacement foam pad designed precisely for the GRABO HIGH FLOW 300mm baseplate.
  • 150 lbs (68 kg) Safe Lifting Capacity: Maintains a dependable negative-pressure seal across flat, porous, and semi-porous architectural pavers and slabs.
  • Tool-Free Fast Field Swaps: Clips directly onto the 300mm suction plate channels in seconds to eliminate crew downtime on active jobs.
  • High-Density Closed-Cell Rubber: Resists premature degradation from rough concrete dust, ambient job-site debris, and repeated compression cycles.
  • Prevents Hidden Pressure Bleed: Restores optimal motor efficiency and airtight performance, ensuring your vacuum pump doesn't overwork on worn gaskets.

Versatile Applications

  • Standard Concrete Pavers: Lift, align, and position interlocking patio stones, driveway pavers, and standard stepping blocks.
  • Flat Sawn Stone & Granite: Handle smooth sawn bluestone, thermal-finish granite, and precast concrete architectural elements.
  • Porcelain & Masonry Slabs: Set outdoor-rated porcelain pavers and patio floor tiles into mortar or compacted sand beds.

FAQs

  • Is this product a complete vacuum lifter?

    No. This product is a replacement consumable foam seal. A GRABO HIGH FLOW tool equipped with a 300mm suction plate is required to use this seal.

  • How does the FS300 standard seal differ from the SMART CUT 300 seal?

    The standard FS300 is an uncut flat foam pad optimized for general flat and standard porous pavers. The SMART CUT version features specialized contour channels engineered to conform around extremely rough, split-face stone and deeply textured aggregates.

  • How often should I replace the foam seal?

    Foam seals are wearable consumables. When working frequently with coarse concrete or abrasive stone, inspect the edges daily. Replace the pad whenever you notice visible fraying, permanent compression grooves, or deep surface gouges that lead to vacuum pressure loss.

  • Can this seal be used directly on the standard GRABO Pro?

    No. This 12" × 12" square seal is engineered specifically for the 300mm suction plate attachment used on the GRABO HIGH FLOW model.
