Spare resin mixer nozzle built to replace a static mixer that has hardened or blocked mid-installation, without needing to discard the rest of the cartridge. The internal helix design blends resin and hardener more efficiently than a standard mixer, cutting extrusion force and wastage. It fits all common resin and cartridge types, making it a practical spare to keep on site or at the counter regardless of which chemical anchor brand is in use.
How a blocked nozzle wastes a full cartridge of resin
Two-part resin starts curing the moment it passes through the mixer, and if the job is paused for more than a few minutes the resin sets solid inside the nozzle. Once that happens, the rest of the cartridge is unusable unless the hardened nozzle can be removed and replaced, which often means the remaining resin is thrown away along with a good part of the job's budget. Swapping in a spare mixer nozzle lets the cartridge be reused immediately, so a five-minute delay on site doesn't turn into a wasted cartridge.
Key Features
-
Internal helix mixing design: Blends resin and hardener more thoroughly than a standard static mixer, reducing the risk of an incomplete cure at the point of application
-
Lower extrusion force: Easier to dispense by hand or gun, reducing fatigue on jobs with a high number of fixings
-
Faster extrusion: Cuts the time spent per fixing when working through a large rebar or stud installation run
-
Reduced wastage: Less resin left unused inside the mixer compared with standard nozzle designs
-
Universal fit: Works with resin and cartridge systems across brands, so one spare nozzle type covers multiple cartridge ranges
-
Point of sale ready: Packaged for easy display and quick counter sale alongside resin cartridges

Who is this for
Groundworkers, steel fixers and structural installers working through multi-fixing rebar or stud installation runs where a job may be paused partway through a cartridge. Builders' merchants and trade counters also stock it as a low-cost point of sale spare alongside resin cartridges, for customers who need a replacement nozzle rather than a full new cartridge.
Typical applications
-
Replacing a nozzle that has hardened after a job was paused partway through a resin cartridge
-
Keeping as a site spare during large rebar or threaded stud installation runs with multiple fixings per cartridge
-
Stocking at builders' merchant counters as a low-cost point of sale item alongside resin cartridges
-
Fitting to a cartridge when the original mixer has cracked or been damaged during handling
-
Swapping mid-installation when switching between different resin cartridge brands using the same gun
-
Reducing resin wastage on jobs with long gaps between individual fixings
How to use
Step 1: Remove the blocked, damaged or original nozzle from the cartridge thread.
Step 2: Screw the new mixer nozzle onto the cartridge fully, ensuring it seats securely over both component openings.
Step 3: Extrude a small amount of resin to waste until an even, consistent colour is achieved.
Step 4: Continue the fixing as normal, following the resin manufacturer's hole preparation and cure time instructions.
Step 5: Dispose of the used nozzle once the job or cartridge is finished, it cannot be cleaned and reused.
Common mistakes
-
Reusing a nozzle after resin has cured inside it: the mixing chamber is permanently blocked and will not extrude cleanly
-
Not extruding to waste before continuing: skipping this step risks injecting poorly mixed resin into the first fixing after a nozzle change
-
Forcing a nozzle that doesn't seat correctly: a loose fit lets resin leak at the join instead of mixing properly inside the nozzle
-
Assuming the cartridge itself is blocked: often it's only the nozzle, and a full cartridge replacement isn't necessary
Safety
Wear appropriate hand and eye protection when handling uncured resin during a nozzle change, as with any two-part epoxy or resin system. Dispose of the used nozzle according to site waste procedures once cured, it is not reusable or recyclable as a mixed component.
Maintenance
No maintenance applies, this is a single use disposable component. Store spare nozzles in their original packaging in a dry location until needed.
Frequently Asked Questions
Q: Will this nozzle fit my existing chemical anchor cartridge?
A: Yes. The internal helix design is built to a universal fit, working with epoxy, vinylester and polyester resin cartridges across brands rather than being locked to one manufacturer's own system. Simply remove the original cap or blocked nozzle and screw this one on in its place. If a cartridge uses a non-standard thread fitting, check the fitting before ordering.
Q: How does the internal helix design improve mixing over a standard nozzle?
A: A standard static mixer relies on a simple set of internal baffles to combine resin and hardener as they're extruded. This nozzle uses a tighter internal helix that folds the two components together more times over the same length, producing a more even mix with less pressure needed to push it through. That lower extrusion force is why it dispenses faster and with less hand fatigue than a standard mixer, particularly noticeable across a long run of fixings.
Q: What is this nozzle NOT suitable for?
A: This nozzle is not a substitute for a blocked cartridge itself. If resin has cured inside the cartridge body rather than just the nozzle, replacing the nozzle alone will not restore it. It's a single use, disposable item and should not be cleaned out and reused once resin has set inside it.
Q: Why choose this nozzle over the standard mixer supplied with a cartridge?
A: The standard mixer supplied with most cartridges is adequate for a single continuous application, but it's not designed to be swapped mid-job. This nozzle is built specifically as a spare, so a paused job that lets resin start curing in the original mixer doesn't mean discarding the rest of the cartridge. Its internal helix also extrudes with less force and less wastage than many standard mixers supplied as-is.
Q: How do I fit a replacement nozzle onto a cartridge mid-job?
A: Unscrew the blocked or original mixer from the cartridge thread, taking care not to disturb the two component openings underneath. Screw the new nozzle on fully, then extrude a small amount to waste until an even colour is achieved before continuing the fixing. This confirms the new nozzle is mixing correctly before it's used on a structural fixing.
Q: Can a mixer nozzle be reused once resin has cured inside it?
A: No. Once resin cures inside the internal helix, it cannot be cleaned out and reused, the cured material blocks the mixing chamber permanently. Each nozzle is designed as a single use, disposable component, replaced whenever a cartridge is reopened after a pause or when a new cartridge is started.
