A dedicated tensioner and sealer for steel banding
The KZL-32 and KZS-32 divide the job between two dedicated air-powered tools: tension the band, then close the seal. This setup suits steel, pipe and plate bundling where separate tools fit the workflow.
Check your setup before orderingSteel strap โข Compatible metal seals โข External compressed air required
This is a separate tensioner-and-sealer workflow. Confirm strap width, thickness, steel grade and seal type together. These tools are not for PP/PET plastic strap.
Why choose this setup?
-
Less repeated hand tensioning: pneumatic power handles the pulling stage.
-
Dedicated tools for each task: KZL tensions; KZS seals. Plan the working space for both tools.
-
Application-led selection: match the steel band and joint to your actual package and workstation.
Choose the right configuration
| KZL-32 tensioner |
Tensions the steel strap. Use with a compatible sealer to complete the joint. |
| KZS-32 sealer |
Closes the compatible metal seal. It does not replace the tensioner. |
| 32 mm setup |
32 mm wide ร 0.8โ1.2 mm thick steel strap (approximately 1.260 ร 0.031โ0.047 in.). Confirm steel grade and seal. |
| Other widths |
Need 25 mm or 19 mm? Request configuration confirmation before ordering. The model name alone does not establish compatibility. |
| Working air pressure |
Approximately 58โ87 psi / 4โ6 bar / 0.4โ0.6 MPa. |
Width options are configurations, not automatic universal compatibility. Confirm any parts or adjustment required to change widths. Inch conversions are approximate; nominal inch categories do not replace actual metric dimensions.
Check your air supply
Working pressure: 58โ87 psi / 0.4โ0.6 MPa.
Pressure alone is not enough: your compressor must also deliver adequate airflow while the tool operates. Tank size and motor horsepower alone do not establish compatibility.
-
Air preparation: use filtered, regulated and lubricated compressed air as specified in the supplied manual.
-
Hose sizing: Confirm the hose and branch-line sizing for the paired tools and your installation.
-
Connections: confirm inlet thread, coupler type and hose connection before ordering; do not assume NPT and BSP fittings interchange.
-
Continuous or shared use: provide compressor delivery flow, operating pressure, hose length and the number of tools used simultaneously so the installation can be checked.

Where this tool fits
-
Steel tube, bar and section bundles: check bundle stability, seal position and tool access.
-
Plate and metal-product packing: check the support surface and edge protection required by your packaging plan.
-
Repeat industrial dispatch work: arrange the air supply and working position around your packing process.
For coils, curved packages or restricted access, send package dimensions and photos before selecting. Fit depends on tool clearance and joint position, not just the strap width.
Plan a complete workstation
Check the order contents before purchase. Confirm the selected tool configuration and both tools in the set, supplied fittings and any accessories. Steel strap, matching seals, an air source, air-preparation components, hose/couplers and any balancer must be accounted for; do not assume accessories shown in application material are included.
From setup to a checked joint
Follow the supplied model-specific manual to prepare the strap and seal, position the tool, tension the band, complete the joint and release the tool. Inspect a trial joint before starting a batch. For the separate-tool setup, follow the specified cutting/release procedure.
Use trained operators and appropriate eye and hand protection. Disconnect the air supply before adjustment, cleaning or maintenance. Strapping is for packaging, not lifting. Tool tension and joint strength are not finished-package load ratings.
Questions before you buy
Does this tool need metal seals?
Yes. Match the seal type and dimensions to the selected tool and steel strap. These KZ tools should not be confused with a sealless steel-strapping tool.
Will my existing compressor work?
Check both working pressure and delivered airflow, plus hose and connection sizing. Send the compressor specification and intended workload for a setup check; pressure or tank capacity alone is not sufficient.
Can one tool handle every listed width?
Do not assume so. Width options may require a different setup or parts. Order the configuration that matches your actual strap.
What should I check if tensioning or sealing is poor?
Stop using an unsatisfactory joint. Check strap/seal compatibility, working air supply and tool condition against the supplied manual. Disconnect air before servicing; contact us with the model and photos for assistance.
