Description
Filling/vent cap in polypropylene (PP) with a 53 mm size is a laboratory closure designed for controlled filling and venting on compatible containers. The cap provides hose connections for 6,3 mm tubing, enabling straightforward linkage to laboratory lines during fill or vent operations. Manufactured from PP, it suits routine labware use with carboys, bottles and related vessels where a dedicated filling and venting interface is required. Supplied as a single piece with a weight of 0,136 kg, it is practical for individual replacement or workstation kits. This filling/vent cap from manufacturer Nalgene belongs to laboratory container accessories used with bottles, canisters and similar vessels. The 53 mm format and 6,3 mm hose connections give a clear mechanical match for systems specified to those dimensions. Polypropylene construction supports typical laboratory handling of plastic closures, while the combined filling and vent function streamlines setup when transferring or equalising pressure on larger lab containers.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Filling/vent cap, PP, 53 mm, connections for hoses 6,3 mm, 1 unit(s)
What is this article?
Filling/vent cap, PP, 53 mm, connections for hoses 6,3 mm, 1 unit(s) is the article on this page. Luminix Health distributes Nalgene 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.
