Description
Hose connector 1/8 inch, 3,2 mm, 1/8 PT is a brass laboratory fitting for vacuum tubing connections. It links flexible hose of the matching diameter to a threaded vacuum port, supporting stable vacuum transfer in everyday laboratory work. The 1/8 inch hose side corresponds to 3,2 mm tubing, while the 1/8 PT thread engages standard pump and manifold fittings for a secure join. Made of brass, the connector offers mechanical durability at both the barb and thread interfaces under typical lab conditions. According to the manufacturer data it is suitable for all vacuum pumps, so it serves as a versatile accessory or spare across mixed instrument fleets. From manufacturer Witeg, the part is supplied as a single piece for straightforward stock replenishment and field replacement. Typical uses include connecting vacuum pumps to filtration set-ups, desiccators, manifolds and general vacuum lines where a compact brass hose-to-thread transition is required. Its simple geometry allows quick installation without specialised tools, helping laboratories keep vacuum systems in service with minimal downtime. Research, quality-control and teaching labs that standardise small-bore vacuum tubing will find this connector a practical addition to routine labware inventories.

What is this article?
Hose barb 1/8 inch, 3.2mm, 1/8PT, for 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.
