Watch all three setups crimped back to back on our small auto capping machine:
2ml/3ml/7ml glass vial crimping machine
Buyers shopping for a small auto capping machine usually already know exactly what they need to run - a specific glass vial size, paired with a specific flip off seal size.
This video walks through three of the most common setups we build: a 2ml glass injection vial with a 13mm aluminum-plastic flip off seal, a 3ml glass vial also on a 13mm flip off seal, and a 7ml glass vial stepping up to a 20mm flip off seal, all crimped back to back on the same class of machine.
Three Glass Vials, Three Flip Off Seal Sizes, One Machine Class
The video above was filmed during a recent pre-shipment run, and it covers three different glass vial and flip off seal configurations on our small auto capping machines.
| Glass Vial Volume | Glass Vial Size | Flip Off Seal Size |
|---|---|---|
| 2ml | 16 × 27mm | 13mm aluminum-plastic flip off seal |
| 3ml | 16 × 35mm | 13mm aluminum-plastic flip off seal |
| 7ml | 22 × 40mm | 20mm aluminum-plastic flip off seal |
Adjustable Doesn't Always Mean "All-in-One"
Our small auto capping machines are fully size-adjustable - a single unit can be reconfigured to handle multiple glass vial and flip off seal sizes, which is exactly what makes them practical for smaller operations that don't want to invest in a separate machine for every format they run.

Here's the part that surprises a lot of new buyers:
even though one machine can technically crimp several sizes, most of our returning customers still choose to run one machine per size.
It's not a limitation of the equipment - it's a production choice.
Keeping one machine locked to one size keeps the line simpler to manage day to day,
with less time spent switching setups between batches.
Why This Matters When You're Buying
If you're deciding between one flexible machine or a few dedicated ones, both are valid approaches - it really comes down to how your production runs. A single adjustable machine makes sense for smaller, mixed-batch operations. Dedicated machines per size tend to win out once volume grows and consistency across long runs becomes the priority. Either way, every machine - adjustable or dedicated - goes through the same crimping test before it ships.

Where These Vial crimping machine Get Used
13mm flip off seal - 10ml sterile water vial
Compounding pharmacies hand-sealing small batches of sterile water used as diluent for peptide or HGH reconstitution.
13mm flip off seal - 30ml bacteriostatic water vial
Telehealth or DTC pharmacies packaging patient-specific bacteriostatic water orders in small runs.
20mm flip off seal - 30ml sterile water for injection vial
Hospital pharmacies repackaging bulk sterile water for injection into smaller dosing vials on demand.
20mm crimp cap - 50ml sterile water vial
Veterinary clinics preparing diluent vials on-site for vaccine or medication reconstitution.
24mm crimp cap - 100ml sterile water for irrigation bottle
Small clinics or medical facilities manually sealing irrigation-grade sterile water bottles in low-volume settings.
32mm crimp cap - 250ml multi-dose sterile water bottle
Mobile or field medical use, where a bench-top capping machine isn't practical.
