Product Advantages & Technical Features

Bayonet Static Epoxy Mixing Nozzles

Designed for flawless small-volume dispensing, this high-performance bayonet mixer nozzle guarantees homogeneous mixing of two-part epoxies, polyurethanes, and silicones — whether applied manually or with pneumatic guns. The robust bayonet twist-lock system allows tool-free, ultra-fast nozzle changes, keeping production lines moving without interruption.

  • Perfectly supports 1:1 and 2:1 ratios with outstanding mixing consistency
  • Secure bayonet interface engineered for hundreds of repeated attachments
  • Wide selection of tip styles: stepped, tapered, straight, Luer lock, Luer slip, and H-tapered
  • Traditional round helical mixing elements for thorough blending
  • Shorter square-profile mixing elements that dramatically reduce retained volume and material waste while preserving excellent homogeneity

Frequently Asked Questions (FAQ)

Q1 What cartridge systems does this bayonet mixer nozzle fit?

It locks securely onto all industry-standard 50 ml dual cartridges and reliably handles 1:1 and 2:1 mix ratios with zero leakage.

Q2 Can I attach dispensing needles for micro-precision output?

Yes, models with luer-lock outlets accept precision needles directly, enabling consistent beads well below 1 mm for electronics and medical assembly.

Q3 How many mixing elements provide the best performance?

More elements ensure superior homogeneity, especially with high-viscosity or fast-reacting materials, delivering uniform cure and maximum bond strength in critical assemblies.

Q4 Are these nozzles reusable?

They are engineered as single-use to eliminate cleaning, prevent cross-contamination, and guarantee consistent, contamination-free results every time.

Q5 What materials are used in the nozzle construction?

The housing uses tough, chemical-resistant polypropylene (PP), while the mixing elements are precision-molded from low-friction POM (Acetal) for smooth flow, minimal pressure drop, and long-term reliability.
