The Topex Sealant Cartridge Applicator Nozzle 21B330-1 is an accessory designed to fit standard sealant and caulking cartridges. It provides a controlled outlet for sealants, adhesives and silicones, enabling accurate bead formation and targeted material application. The nozzle is intended for quick fitting and replacement on compatible caulking guns, helping achieve consistent extrusion and reducing waste during repair, installation or finishing work.
Advantages
This nozzle offers a narrow, controlled flow path that improves precision when applying sealants and adhesives. Its design facilitates cleaner joints and more uniform beads compared with freehand dispensing. The accessory is simple to install and remove, allowing users to switch between nozzle sizes or materials quickly. Constructed to work with common cartridge formats, it supports routine maintenance, renovation and sealing tasks with minimal setup time.
Suitable for
- Applying silicone, acrylic or polyurethane sealants in bathroom and kitchen joints

- Sealing joints in construction and renovation projects
- Precision adhesive dispensing for small repair and DIY tasks
Key specifications
- Compatibility: fits standard sealant and caulking cartridges
- Material: durable plastic suitable for common sealant chemistries
- Outlet shape: tapered for controlled bead profile and variable bead width
- Mounting: push-fit or screw-fit connection depending on cartridge type
- Replacement: designed for easy removal and replacement during use
How to use
Attach the nozzle to a standard sealant cartridge according to the cartridge’s connection type, ensuring a secure fit. Trim the tip of the nozzle to the desired bead diameter and angle for the task. Insert the fitted cartridge into a compatible caulking gun, apply steady pressure to dispense the sealant, and move the gun along the joint at an even pace to form a uniform bead. After use, remove any residual material from the nozzle and either cap it or replace it as needed to prevent clogging.
Usage recommendations
For best results, select nozzle tip size and cutting angle based on joint width and desired bead shape. Use appropriate personal protective equipment and follow sealant manufacturer instructions regarding substrate preparation, curing times and compatibility with materials.
