Applications
Buyers rarely start with a model number. They start with a bottle and a product. These are the five applications we tool for, and what each one actually demands of a closure.
Typical hazards: Return-and-refill barrels, long warehouse storage, dispenser compatibility
The two failures that matter here are a tamper ring that will not break cleanly and a cap that seeps once pallets are stacked three high. Barrel necks in 45 mm and 55 mm, with matching carry handles and a self-sealing non-spill option for dispensers.
Typical hazards: High-speed capping, hot-fill deformation, carbonation pressure
Beverage lines run fast, so application torque and cap geometry have to suit your capper rather than the bench. Tell us the line speed and whether you hot-fill — both change the liner we recommend.
Typical hazards: Oil creep at the thread, drip after pouring, long shelf life
Oil finds every gap a water cap gets away with. Wide-mouth necks with a sealing liner, plus matching preforms and carry handles for jerrycan formats.
Typical hazards: Moisture ingress, pilferage, retail shelf presentation
Supplement packs are judged on the shelf and on the seal. Induction seal liners and desiccant-tube inserts, with clear and tinted over-caps where the pack has to look like a premium product.
Typical hazards: Viscous product, repeated opening, staining and odour transfer
A condiment cap gets opened hundreds of times, not once. Grip and a liner that reseals matter more than they do on a water bottle, and food-contact resin has to hold up against acid and oil.
How to specify
Most cap complaints trace back to a specification decision, not a moulding defect. Working through these four in order avoids the usual mismatches.
The outside diameter of the finish and the thread type. Everything else about the bottle is irrelevant to whether our cap fits it.
Still water, carbonated, hot-filled, oil or a dry supplement. This decides the resin, the liner and whether you need a barrier at all.
Manual, semi-auto or inline at speed. Application torque is set for the line, and a cap specified for a bench will slip on a fast head.
The EU and the US both need food-contact documentation we do not hold yet. Say so early and we will tell you honestly what it takes to close that gap.

A dash means we do not currently tool that combination — not that it cannot be made. The last row is the honest answer to most enquiries: if your neck is not on this list, it becomes a mould conversation rather than a catalogue one.
