Description
The Medmix Sulzer Mixpac MBH 03-12D static mixer is a 12-element mixing nozzle built for the B-System line of two-component cartridges. It snaps onto the cartridge’s bayonet fitting and blends resin and hardener into a uniform mix as the material passes through the helical elements, so the adhesive, sealant, or potting compound that reaches the substrate cures the way the manufacturer engineered it to.
Sulzer Mixpac rebranded as Medmix in 2021, so you may see this part cataloged under either name depending on the source, but the tooling, part numbers, and fit are unchanged.
What the MBH 03-12D Static Mixer Code Means
Mixpac part numbers follow a set pattern: the first number is the mixer’s nominal bore diameter in millimeters, the second number is the element count, and the trailing letter identifies the outlet style. On the MBH 03-12D static mixer that works out to a 3mm bore, the narrowest in the MBH lineup carried here, 12 mixing elements, and a D outlet, a direct, non-tapered tip sized to seat straight onto the dispensing nozzle rather than stepping down through a taper. The narrow bore suits lower-volume dispensing where precise bead control matters more than throughput.

MBH 03-12D Static Mixer Cartridge Fit
The MBH series is built for B-System S-Style 50ml cartridges, the smaller-format size common on hand-gun dispensed two-part adhesives and sealants used in fabrication shops and field installation work. The bayonet attachment locks the mixer in place under hand-gun pressure without needing a threaded nut.
Applications
Fabricators and installers reach for the MBH 03-12D static mixer on precision bead work, small-fixture bonding, and general two-component sealant jobs sized for 50ml cartridges. Because it is a wear item rather than a reusable fitting, most shops keep a box on hand and swap a fresh mixer with every new cartridge rather than risk cross-contamination or a partially cured plug from a leftover mixer.
Chemical Concepts stocks the full dispensers, mixers, and nozzles line alongside the two-component adhesives and sealants that use them, so you can order the cartridge and the correct mixer together.
