Description
Hose connector 1/4 inch, 6 mm, 1/8 PT is a laboratory fitting for vacuum tubing connections on Rocker pump systems. It joins flexible hose of 1/4 inch / 6 mm diameter to a 1/8 PT threaded port, enabling a secure vacuum line between pump and apparatus. The connector is specified for Rocker 300, 300DC, 400, 410 and 430, so it matches the hose and thread interfaces commonly used with that instrument family. From manufacturer Witeg, the part is supplied as a single piece for easy stock keeping and on-site replacement. In laboratory workflows such connectors support filtration set-ups, manifold links and general vacuum transfer where a defined hose-to-thread transition is required. The clear dimensional designation (1/4 inch, 6 mm hose side and 1/8 PT thread) helps technicians select the correct spare without trial fitting. Research, quality-control and teaching laboratories that standardise on Rocker vacuum pumps can use this connector to maintain consistent tubing layouts across multiple units. Quick installation keeps downtime low during routine maintenance or system reconfiguration. As a dedicated accessory for the listed Rocker models, it complements existing vacuum labware inventories and supports reliable day-to-day vacuum operation.

Questions about Hose barb,1/8 PT, 1/4 inch, 6 mm
What is this article?
Hose barb,1/8 PT, 1/4 inch, 6 mm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
