The combination of flow control and high dispensing force help you to use all of the sealant while reducing overspill or waste.

Reducing waste and giving you control

As the range of caulking applications grows from sealants and adhesives to firestop products, so does the requirement for dispensers that do away with the mess, and give you control.

Unblocking clogged nozzles, managing flow rate or cleaning up overspill wastes too much of your time – so we've engineered the CD 4-A22 specifically to cut these annoyances out of your day.

With 5,000N of dispensing force and a switchable capacity from 310 ml to 600 ml, you have high flexibility for your working range. The combination of a 6-speed dial for adjustable flow rate and variable speed trigger allow for a precisely controlled flow of sealant or adhesive. Furthermore, the auto-reverse function stops drips and material waste, saving time and money.

The CD 4-A22 is fully compatible with our 22V range of cordless tools, so you can use the batteries you have, without the need to search for an additional power source. When combined with a Hilti B 22/5.2 Ah battery it will continue to perform as long as your working day.


Ease of use for firestop applications

Sealing top-of-wall and bottom-of-wall is important for both firestop and architectural needs. Due to its extremely precise control, the CD 4-A22 is the ideal tool for sealing joints against fire and smoke when you need a visually attractive finish. Additional specifications – such as acoustics or joint movement – can be fulfilled with the right choice of Hilti firestop product.
