Description
Aluminium crimp caps with a red PTFE-coated rubber sealing disc provide a secure closure option for compatible small laboratory vials. These N-8 size caps are supplied with a centre hole for needle or septum access and are packed as 100 pieces per unit from manufacturer Witeg. The aluminium shell combined with the PTFE-coated rubber disc supports reliable crimp sealing in analytical, pharmaceutical and general laboratory workflows. The red sealing disc helps identify the liner type at a glance during preparation and sampling. Designed for use with matching N-8 roll-rim or crimp-neck vials, the caps suit routine sample containment, injection and short-term storage steps where a pierced or accessible septum is required. Their compact format and consistent cap geometry support repeatable sealing on standard laboratory crimping tools. Suitable for research, quality-control and production-support benches that standardise on N-8 aluminium crimp closures with PTFE-faced rubber liners.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Aluminum crimp caps
What is this article?
Aluminum crimp caps is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
