Reliable Grip for Heavy Tiles – The Professional Replacement Suction Cup
The Replacement Suction Cup with Vacuum Indicator and Quick-Action Lever (Item No. 21575) is the ideal solution for tilers, stone workers, and craftsmen who demand maximum safety and precision when handling large-format or heavy panels. Designed for professional use, this suction cup impresses with its robust construction, easy handling, and exceptional holding power – even on textured or slightly porous surfaces.
As a compatible spare part for the Sigma Kera-Lift Installation Frame (art.-no. 12225), it ensures seamless functionality and maintains the full performance of your installation system. Perfect for those who regularly work with porcelain stoneware, Kerlite, natural stone, or glass panels and want to avoid any risk.
Typical Applications and On-Site Use
In daily work, suction cups can wear out due to heavy use or lose grip due to dirt or damage. A replacement suction cup with original specifications is essential to:
- fully restore the structural stability of the installation frame,
- ensure flawless vacuum grip on particularly delicate tiles,
- quickly and reliably fix temporary failures of individual suction cups.
The quick-action lever makes the suction cup ready to use in seconds – a crucial advantage when working under time pressure or frequently repositioning on-site.

- Vacuum Indicator: color-coded for visual grip control

- Compatibility: fits Sigma Kera-Lift Installation Frame (art.-no. 12225)
Superior Replacement for Conventional Suction Cups
Unlike basic suction lifters without a vacuum indicator, this model provides clear visual control of the suction pressure – a major benefit when working with high-value or fragile materials. The integrated quick-action lever enables fast activation and secure fit, even when frequently repositioned or used on slightly curved surfaces.
Thanks to the replaceable suction pad and durable mechanism, this suction cup offers long service life and cost-effective maintenance. Its precise fit with the Kera-Lift system ensures it is ready for use without any adjustments.
Maintenance, Care & Application Tips
- Clean the suction surface thoroughly before each use to remove dust or grease.
- Check the vacuum indicator regularly. If insufficient vacuum is indicated, operate the lever again or reposition the suction cup.
- Store the suction cup flat and dry, preferably in a padded compartment.
- Avoid harsh cleaners that may damage the rubber compound.

FAQ – Frequently Asked Questions About the Replacement Suction Cup with Vacuum Indicator and Quick-Action Lever
Is the replacement suction cup compatible with all Kera-Lift models?
Yes, the suction cup (art.-no. 21575) is specifically tailored to the Sigma Kera-Lift Installation Frame (art.-no. 12225). It can also be used with other models that share the same mounting system.
Can I use the suction cup on its own, without the frame?
Yes, it can be used individually, e.g., for temporary lifting or positioning of smaller panels. For long-term secure installation, it should be integrated into the frame system.
How often should the suction cup be replaced?
That depends on frequency of use, surface conditions, and care. For professional use, it's advisable to regularly test the holding strength and replace if worn or visibly cracked.
Does the suction cup work on textured tiles?
Yes, the special rubber compound and flexible design allow good adhesion even on lightly textured or satin surfaces. However, a clean surface is essential.
Can I check the vacuum pressure?
Yes, the integrated color-coded vacuum indicator provides visual feedback on current holding power – a vital safety feature on-site.
Is replacement complicated?
No, replacement is tool-free and takes only a few seconds. The new suction cup is simply inserted into the Kera-Lift frame holder and ready for immediate use.
How should I store the suction cup?
Store flat, dry, and dust-free – ideally in a box or pouch that protects the rubber from deformation or contamination. Avoid direct sunlight.
How can I identify a defective suction cup?
If the vacuum does not hold, the indicator shows “low pressure,” or cracks are visible, the suction cup should be replaced immediately to avoid accidents or material damage.
Is the suction cup available as a set?
Yes, replacement suction cup sets are available in the Karl Dahm online shop – for example, to fully equip the Kera-Lift frame with eight new elements.
What warranty is included?
As with all professional tools, Karl Dahm offers warranty against material and manufacturing defects. Please refer to the product description or warranty terms on the website for details.
