Description
Overview
The GRABO RK13001 Type A1 foam-rubber seal replaces a worn or damaged sealing element on a compatible GRABO lifter. The high-friction, closed-cell construction forms the contact area between the tool and the material; replacing a worn seal helps restore the tool’s ability to maintain its intended vacuum.
Features
- Hand-replaceable seal for routine maintenance.
- Closed-cell rubber construction with black and red material components.
- Replacement for an existing seal, not an upgrade to the tool’s rated lifting capacity.

Applications
Use when the existing Type A1 seal is worn, damaged or no longer maintaining the expected seal. Confirm the replacement type against the tool before fitting it; a fresh seal cannot compensate for an unsuitable surface or an excessive load.
Selection and Use
- Inspect the contact surface and seal before lifting and verify vacuum after replacement.
- Material test values describe the seal components, not a working-load rating for the lifter.
- Store the spare at room temperature and protect its sealing surfaces from damage.
