Description
Hose connector 5/16 inch, 8 mm, 1/8 PT is a brass fitting designed for vacuum-pump hose connections in the laboratory. The connector combines a 5/16 inch (8 mm) hose barb with a 1/8 PT threaded end, enabling secure attachment of flexible tubing to vacuum pumps and related apparatus. Manufactured from brass, it provides durable, leak-resistant performance for everyday vacuum service. Explicitly intended for use with all vacuum pumps, this hose connector from manufacturer Witeg simplifies the link between pump ports and laboratory tubing lines. Supplied as a single piece, it serves as a practical lab material item for setting up or maintaining vacuum systems in research, teaching and analytical environments. The dual 5/16 inch / 8 mm hose side accommodates common tubing sizes, while the 1/8 PT thread matches standard pump and manifold ports. Compact and robust, the brass construction withstands typical laboratory vacuum conditions and repeated assembly cycles, offering a reliable interface component for vacuum-line configurations.

Questions about Hose barb 5/16inch, 8mm, 1/8PT, for al
What is this article?
Hose barb 5/16inch, 8mm, 1/8PT, for al 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.
