The Opti-Mix® static mixing nozzle is specifically designed for crack injection epoxies and ensures thorough mixing of epoxy components:
- For use with both low viscosity and gel viscosity ETI formulations.
- Flow regulators ensure that resin and hardener flow at equal rates and prevent mixed epoxy from flowing back out of the nozzle into the cartridge. This ensures thorough mixing and prevents mixed product from curing in the neck of the cartridge, causing blockage. Testing shows that mixing with the Opti-Mix nozzle is 4 times more consistent than a standard spiral mixing nozzle.
- For use with both pneumatic and manual dispensing tools.
- Half the length of standard spiral mixing nozzles, allowing easy access in cramped conditions and reducing waste.
- Barbed end allows easy attachment to the E-Z-Click Injection Fitting.
- When dispensing low viscosity material, using a standard spiral mixing nozzle and a manual dispensing tool, resin and hardener surge unevenly through the nozzle without being thoroughly combined. The result is poorly mixed epoxy that will not fully cure and will not effectively repair the crack. The Opti-Mix nozzle corrects this problem utilizing unique mixing elements and a flow regulator that allows the use of a manual tool with low viscosity epoxy.
This photo shows low viscosity epoxy mixed with a standard mixing nozzle (left) and with the Opti-Mix nozzle (right). Testing shows that epoxy mixed with the Opti-Mix nozzle has over 20% more strength than samples mixed with a standard mixing nozzle.
E-Z-Click Ports and Injection Fitting
The E-Z-Click Injection System is comprised of a specially designed fitting and ports that take the mess out of your repair project while allowing you to work faster. The E-Z-Click Injection Fitting™ installs onto the end of the Opti-Mix mixing nozzle and clicks onto the E-Z-Click Ports™ during injection.
- Positive connection eliminates messy leakage, minimizing waste and clean-up.
- No drilling of ports: E-Z-Click Ports perform while pasted to the surface of the concrete. No drilling required for most applications.
- Disconnect the fitting and the epoxy stops flowing, no leaky mess.
- After injecting, pull the head of the E-Z-Click Port out to close it and prevent leakage.
- One person can work faster without having to hold the tube on the port.

Flush Mount Port
ETR Epoxy Paste
Ideal for pasting over the surface of cracks and attaching ports for pressure injection. The non-sag paste consistency enables paste-up on horizontal, vertical and overhead applications. Fast cure time means shorter time between paste-over and injection. Packaged as a kit in separate 8 oz. canisters which are mixed manually to yield 16 ounces of epoxy. Also ideal for small concrete repair application: spall repair and misc. patching.
