Set Components - what's included in the 13mm closure set
The 13mm vial closure set consists of two distinct components engineered to work together - a rubber stopper providing the compression seal, and an aluminum cap providing the crimped retention and tamper-evidence layer. Each component is independently specified, independently quality-checked, and independently orderable.
13mm rubber stopper
Bromobutyl elastomer · compression seal
The primary sealing component - a bromobutyl rubber stopper sized for 13mm vial neck applications, providing the compression seal against the glass vial neck once crimped under the aluminum cap. Available in standard or custom hardness formulations.
✓ Orderable as standalone item
✓ Bromobutyl - pharmacopoeial standard
✓ USP <381> reference material
13mm aluminum cap
Flip-off / tear-off · crimp retention
The secondary retention and tamper-evidence component - an aluminum cap sized for 13mm crimping, available in flip-off or tear-off opening style, custom colour, and custom logo/branding printing or embossing.
✓ Orderable as standalone item
✓ Flip-off or tear-off opening style
✓ Custom colour, print, or embossed logo

Why we call it a "set" rather than a single product
The stopper and cap are manufactured on separate production lines, using entirely different materials and processes (rubber compounding/moulding vs aluminum stamping/forming). Calling them a "set" reflects that they are two genuinely independent components that happen to be commonly ordered together - not a single moulded or fused part. This distinction matters for how you can order, combine, and use them.
Pre-assembled or separate supply - your choice
The 13mm closure set can be supplied two ways - pre-assembled (stopper seated inside the cap, ready to place on the vial as one unit) or as two separate component streams for independent handling on your fill-finish line. Both options use the identical stopper and cap specifications; only the packing and supply logistics differ.
pre-assembled set
✓ Single placement motion - faster line throughput
✓ Stopper pre-seated correctly - eliminates alignment error
✓ Reduced component handling steps on your line
✓ Single incoming inspection / lot record
✗L ess flexibility to mix stopper/cap combinations
separate component supply
✓ Compatible with existing two-stage filling lines
✓ Mix and match stopper material with different cap colours/styles
✓ Order quantities independently - different reorder cycles
✓ Easier to source one component from elsewhere if needed
✗ Two incoming inspections / two lot records to manage
Which option fits your filling line?
Pre-assembled sets suit single-stage automated lines designed to place one combined closure component per vial - typically the higher-throughput choice. Separate supply suits lines with distinct stoppering and capping stations (common on older or modular equipment), or where you want to combine a standard stopper with multiple cap colour variants for different product SKUs without holding pre-assembled inventory for each combination. Tell us your line configuration and we will recommend the appropriate supply mode.
