SKU CH-H3AD-D384K

Steel catalyst mixer with 28 inch reach blends two-part compounds directly in the cartridge

  • 28-inch steel shaft reaches deep cartridges
  • Catalyst mixing action blends two-part compounds thoroughly
  • Steel construction resists bending under heavy loads
  • Newborn brand trusted for professional dispensing tools
  • Simple hand operation requires no external power

Catalyst Mixer for Two-Part Sealants

The Newborn MX-03 Catalyst Mixer is built to blend two-part caulks and sealants directly in the cartridge. Its steel construction resists wear on automotive and industrial job sites. The 28-inch length provides leverage for thorough mixing without excessive effort.

Steel Build and Cartridge Fit

The all-steel body withstands repeated use with stiff materials and cleans easily after each application. A fixed collar engages standard dual-cartridge nozzles so the mixer stays aligned during operation. No powered driver is required; the long handle gives manual control over mixing speed and pressure.

Manual Mixing Limits

Hand-powered mixing works well for occasional joints but slows production on large seams. Very high-viscosity formulas demand more torque than the lever can comfortably supply. Users needing continuous, high-volume output will find the process labour-intensive compared with pneumatic alternatives.

Questions about this item

What length is the 28" steel shaft designed to reach inside a cartridge?

The 28 inch steel shaft reaches the bottom of standard cartridges so the mixing blades can blend catalyst evenly throughout the material.

What diameter opening does the mixer head need to pass through for insertion?

The mixer head fits through the standard cartridge nozzle opening after the tip is cut, allowing direct placement into the sealant.

How do you attach the mixer to a drill without stripping the chuck?

Insert the hexagonal steel shaft fully into the drill chuck and tighten securely on the flats, not on the rounded portion, to prevent slippage during mixing.
