Description
The Ritter ZWM 18S is a helical static mixer built with an integral nut connection, so it threads directly onto compatible dual-component cartridge and gun outlets without a separate retaining collar. Eighteen helical elements run the length of the mixer body, folding the resin and hardener streams into each other repeatedly before the adhesive or sealant reaches the nozzle tip.
Where This Static Mixer Is Used
This mixer fits two-component structural adhesives, polyurethane and epoxy potting compounds, and sealants dispensed from manual or pneumatic cartridge guns using an integral nut style outlet. Fabrication shops, sign makers, and assembly lines running multi-part chemistries rely on a mixer like this one to keep the ratio consistent shot to shot, which matters most on structural joints where an under-mixed streak can leave a soft spot in an otherwise cured bond line. Swapping a fresh mixer between cartridges also keeps cross-contamination from one adhesive system into the next off the workbench.
Mixing Geometry and Fit
Overall length runs 9.3 inches (236 mm), with an outlet outer diameter of roughly 0.3 inches (8 mm) and inner diameter near 0.2 inches (6.2 mm), sized to run through a 10 mm tube bore. The 18-element helix gives the two components enough residence time and turbulence to blend fully at typical gun-driven flow rates, so the bead coming off the tip is a uniform color and consistency rather than streaked. Because the connection is integral (molded into the mixer body itself), there is no separate nut or collar to lose or cross-thread when swapping mixers between jobs.
