PRODUCT SPECIFICATIONS
13 mm Flip-Off Cap - complete specification
The 13 mm flip-off cap is the most common closure format for small-format injectable vials, antibiotic preparations, and lyophilised drug products. The aluminium skirt crimp-seals to the vial neck; the plastic flip tab provides one-way tamper-evident access.

Tamper-evident flip-off mechanism
The plastic flip tab folds back permanently on opening - it cannot be returned to its original position, providing unambiguous visual tamper evidence. Combined with the crimped aluminium skirt, the 13 mm flip-off cap forms a two-layer tamper-evident closure system that meets USP and EP requirements for injectable vial packaging.
Pharmaceutical grade - CoA included
Manufactured to pharmaceutical grade specifications with dimensional tolerances validated against standard 13 mm vial neck formats. A Certificate of Analysis confirming dimensional specification, colour reference, and material compliance is issued with every production lot. GMP documentation package available on request for supplier qualification.
Factory direct - no trading company markup
We are the manufacturer. Direct sourcing means transparent pricing, accurate lead times, direct technical communication, and consistent quality control across every order. No intermediary, no markup, no quality surprises between batches.
MACHINE COMPATIBILITY
Manual bench crimper
to fully automatic line
The 13 mm flip-off cap dimensions conform to the international standard for 13 mm vial neck crimping, ensuring compatibility across the full spectrum of crimping equipment - from single-vial manual pliers to high-speed rotary crimping heads on automated filling lines running thousands of vials per hour
Semi-automatic & fully automatic lines
Rotary crimping · high-speed · inline
Our 13 mm caps are dimensioned to the international standard for 13 mm crimp-on vial closures - ensuring drop-in compatibility with rotary crimping stations on semi-automatic and fully automatic pharmaceutical filling lines from all major equipment manufacturers including IMA, Bosch, Bausch+Ströbel, Groninger, and others. The consistent aluminium hardness and skirt geometry produce a reliable, uniform crimp across all head types without jamming or double-crimping.
Inline rotary crimping stations - all major brands
IMA · Bosch · Bausch+Ströbel · Groninger compatible
High-speed lines: up to 36,000 vials/hour
Consistent Al hardness - no crimp variation across the bag
Suitable for: pharma manufacturers · CMO/CDMO · fill-finish
Manual & bench-top crimping
Hand crimper · Bench pliers · Semi-manual
Our 13 mm caps are fully compatible with hand-held bench-top crimping pliers and semi-manual single-head bench crimpers - the equipment of choice for compounding pharmacies, research laboratories, small-batch clinical trial material production, and veterinary practices. The aluminium skirt thickness and hardness are specified to crimp cleanly in a single-press cycle on standard bench crimpers without requiring excessive hand force.
Hand-held SS crimping pliers - single vial
Bench-top manual single-head crimpers
Semi-manual benchtop rotary head crimpers
Clean crimp in one press - no double-pressing needed
Suitable for: compounding pharmacy · CRO · vet clinic · R&D lab
Machine compatibility testing
We recommend confirming dimensional fit with your specific crimping equipment and vial batch before committing to a production order. Contact us to arrange a sample pack for machine trial - we can provide 100–500 caps for compatibility testing on your line at no charge with a confirmed inquiry.

Bag labelling
Every bag from 500 pcs carries a lot label with product code, colour, quantity, manufacturing date, and our factory reference. Lot labelling supports your incoming inspection and batch record documentation. |
Standard bag = 1,000 pcs
The 1,000-piece sealed PE bag is our most popular format - it matches a typical filling session or small production batch, provides clear lot-level traceability, and is the format used for our stocked colours available for immediate dispatch. |
Custom pack sizes
If your production line requires a different pack count - for example 800 pcs to match your crimping machine hopper capacity - custom bag counts are available on production orders. Contact us to specify. |
STANDARD COLOUR RANGE
Colour-code your vials. Every product, every strength.
Colour differentiation on vial caps is a critical patient safety and production workflow tool - preventing mix-ups between different products, concentrations, or intended patient populations. We stock 10+ standard colours for immediate dispatch; custom Pantone colours are available on production orders.
