Description
Screw cap DIN 51 with drain cock Ø 20 is a practical closure accessory designed for controlled emptying of laboratory and industrial canisters. The cap follows the DIN 51 thread standard and integrates a drain cock with a 20 mm diameter opening, allowing liquids to be dispensed without fully removing the closure. It is expressly suitable for stackable UN canisters, supporting organised storage and safer handling of bulk containers in laboratory, production, and warehouse environments. Supplied as a single piece in a natural colour finish, the unit pairs cleanly with matching canister systems and keeps the dispensing path accessible when containers remain stacked. From manufacturer lab-o-plastix, this screw cap with integrated drain cock addresses everyday needs for secure sealing combined with convenient outflow control. Categories such as screw closures and tamper-evident style closures highlight its role among laboratory packaging components. The design focuses on straightforward mounting on DIN 51 necks and reliable drain-cock operation for routine liquid transfer tasks. Ideal where stackable UN canisters require a dedicated DIN 51 cap that combines closure integrity with an integrated Ø 20 drain cock for controlled dispensing.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw cap DIN 51 with stopcock bore Ø 20, suitable for stackable UN jerrycans
What is this article?
Screw cap DIN 51 with stopcock bore Ø 20, suitable for stackable UN jerrycans 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.
