Description
Adhesive that cures inside the mixing nozzle is money in the trash. Every purge, every stop in the run, and every nozzle you pull off the cartridge takes retained adhesive with it. On expensive epoxies and thermally conductive pastes it adds up fast.
The Xemex X2-A5-7T Low-Waste Static Mixer holds just 0.6 mL of retained volume. Seven Xemex mixing elements in a 50.5 mm body deliver mixing performance equivalent to a 24-element traditional mixer, so less material stays behind in the nozzle on every cycle.
The luer-slip outlet accepts slip-fit needles and dispensing tips for controlled bead placement. The A-system bayonet inlet fits standard bayonet cartridges at 1:1 through 10:1 ratios and works with manual guns, pneumatic guns, and automated or cobot dispensing.
Compatible with epoxies, methacrylates (MMA), urethanes, and silicones. Designed and manufactured in the United States.

Patented Xemex Mixing Technology
Each Xemex element multiplies the striation count, so full mixing happens in seven elements instead of 24. Shorter mixer, same mix quality, less adhesive left inside when you are done.
Performance in Production
- 0.6 mL retained volume, tied with the X2-A5-7L for the lowest in the Xemex line.
- Seven Xemex elements mix like a 24-element traditional nozzle.
- Short 50.5 mm body puts the tip closer to the work surface for better operator control.
- Luer-slip outlet accepts slip-fit needles and precision tips.
- Polyester insert supports moisture-sensitive adhesive systems.
- Fits manual, pneumatic, and automated or cobot dispensing without changing equipment.
Installation and Handling
- Fits standard A-system bayonet cartridge connections.
- Purge a short bead before the first shot to confirm both sides are flowing.
- Replace the mixer once adhesive begins curing inside the nozzle.
- Leave the spent mixer on the cartridge between runs to seal it, then fit a fresh one for the next job.
Common Applications
- Electronics. Potting, encapsulation, and sealing of sensitive components where complete mixing prevents soft spots.
- Automotive. Structural bonding and component assembly, including tight-access and robotic cells.
- Industrial manufacturing. Assembly, sealing, and composite bonding with two-component adhesives.
- Precision and needle-tip dispensing
A-System Tip Options
The A-system bayonet mixer comes in two outlet styles. Same body, same seven elements, same 0.6 mL retained volume. Only the tip changes.
| Part | Outlet | Best For |
|---|---|---|
| X2-A5-7T (this page) | Luer-Slip | Slip-fit needles and tips, quick changes |
| X2-A5-7L | Luer-Lock | Needles that need to stay locked on under pressure |

Frequently Asked Questions
What is the difference between the X2-A5-7T and the X2-A5-7L?
Only the outlet. The 7T has a luer-slip tip that needles push onto by friction. The 7L has a luer-lock tip that threads on and locks. Body, connection, element count, and 0.6 mL retained volume are identical. Pick luer-slip for fast tip changes, luer-lock when a needle has to stay put under dispensing pressure.
Will the X2-A5-7T fit my cartridge?
It fits standard A-system bayonet cartridges at 1:1, 2:1, 4:1, and 10:1 ratios. If your cartridge or meter-mix unit uses a bell, threaded, or F-style outlet, use the matching Xemex connection style from the comparison table above.
How many elements does the X2-A5-7T replace?
Seven Xemex elements deliver mixing performance equivalent to a 24-element traditional mixer. The gain comes from the internal element geometry, not from added mixer length, which is why the retained volume stays at 0.6 mL.
