Description
BOLA Mini couplings in cross design are compact connecting pieces made of polytetrafluoroethylene (PTFE) for laboratory tubing systems. This fitting provides four ports with internal UNF 1/4'' 28G threads that accept matching hollow screws, allowing secure attachment of flexible tubing. It is dimensioned for hose with an inner diameter of 0,8 mm and an outer diameter of 1,6 mm (1/32 × 1/16''), and the overall length is 25 mm. The cross configuration supports multi-way distribution of fluid or gas pathways in analytical, preparative and process laboratory setups where chemical inertness and reliable miniature connections are required. PTFE construction offers broad chemical resistance suitable for aggressive media and high-purity work. These mini couplings from manufacturer Bohlender combine compact geometry with the low-friction, non-stick surface characteristic of fluoropolymers. Offered as a single piece with a net weight of 0,004 kg, the component is well suited to chromatography lines, sample-transfer manifolds and general laboratory fluid handling. The standardised internal thread ensures compatibility with common miniature fluidic accessories used across research and quality-control environments.

Questions about BOLA Miniature Couplings, UNF 1/4'' 28G, Ø 0,8 x 1,6 mm PTFE, 4-way
What is this article?
BOLA Miniature Couplings, UNF 1/4'' 28G, Ø 0,8 x 1,6 mm PTFE, 4-way is the article on this page. Luminix Health distributes Bohlender 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.
