Description
Octagonal cap stopper in PE-HD, blue and round, for oxygen bottles with NS 14 joint geometry provides a plastic closure option for laboratory glassware that uses a standard ground joint. The stated joint size is NS 14/23, matching common small-joint flasks and related vessels where a secure, removable stopper is needed. Manufactured from high-density polyethylene (HDPE), the stopper combines chemical resistance with a lightweight, impact-tolerant body suited to routine handling. The blue colour supports quick visual identification on the bench, while the octagonal cap profile aids grip when inserting or removing the stopper. Intended for oxygen-bottle applications as described by the manufacturer data, this single-piece item from lab-o-plastix is positioned among plastic ground-joint stoppers for laboratory use. It is suitable where a PE-HD NS 14 stopper is preferred over glass for reduced breakage risk and simple cleaning. Use it to close compatible jointed vessels during storage, transport within the lab, or short-term holding of contents according to your local procedures and material compatibility checks.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about NS-plastic-stoppers, HDPE, blue, round, hexagonal for oxygen bottles, NS 14
What is this article?
NS-plastic-stoppers, HDPE, blue, round, hexagonal for oxygen bottles, NS 14 is the article on this page. Luminix Health distributes lab-o-plastix 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.
