The G&B Fissaggi nylon sleeve is a specialized component engineered for use with chemical anchors in hollow masonry, brick, or perforated materials. Measuring 20x85 mm, this sleeve acts as a containment device that prevents the resin from dispersing into the cavities of the base material, ensuring it remains concentrated around the anchor rod for maximum load-bearing capacity. By providing a controlled environment for the chemical injection, it guarantees a secure and reliable fixing point for various structural and non-structural applications.
Advantages
The primary benefit of using this nylon sleeve is its ability to optimize resin consumption while significantly increasing the stability of the anchor in hollow substrates. Its durable nylon construction offers excellent resistance to chemical reactions and environmental factors, ensuring long-term integrity of the installation. The design facilitates an even distribution of the anchoring compound, which prevents waste and ensures that the anchor rod is perfectly centered and firmly bonded to the surrounding material, even in irregular or fragile masonry.
Suitable for
- Installation of heavy-duty fixtures in hollow bricks
- Securing brackets and supports in perforated masonry
- Renovation projects involving porous or hollow base materials
- Professional construction tasks requiring reliable chemical anchoring
When it may not be suitable
This sleeve is specifically designed for hollow or perforated materials and is not intended for use in solid concrete or dense stone, where a sleeve would be unnecessary and could interfere with the bonding process. It is also not suitable for applications requiring extreme fire resistance or high-temperature environments that exceed the thermal limits of nylon.
Key specifications
- Material: High-quality nylon
- Diameter: 20 mm
- Length: 85 mm
- Quantity: 10 pieces per pack
How to use
To use the sleeve, first drill a hole into the masonry according to the required diameter. Clean the hole thoroughly to remove dust and debris, as this is critical for the chemical bond. Insert the nylon sleeve fully into the hole. Inject the chemical resin into the sleeve starting from the bottom, ensuring it fills the sleeve completely without creating air pockets. Insert the threaded rod or anchor bolt into the sleeve with a slow, rotating motion until it reaches the desired depth. Allow the resin to cure according to the manufacturer's instructions before applying any load.
What to consider before purchase
- Verify the diameter of your drill bit matches the sleeve requirements
- Ensure the depth of the hole is sufficient for the 85 mm length
- Check that the base material is compatible with chemical anchoring systems
- Confirm the quantity needed for your specific project size
Usage recommendations
Always wear appropriate personal protective equipment when handling chemical resins and ensure the work area is well-ventilated during the installation process.
