Description
BOLA mini couplings in a straight design connect tubing in laboratory fluid-handling and chromatography setups via an internal UNF 1/4'' 28G thread used with matching hollow screws. This article is the straight POM execution, selected for higher mechanical strength, and fits tubing of 1,6 mm internal diameter by 3,2 mm external diameter (1/16 × 1/8''). Two ports sit on a compact body with a total length of 17 mm, making the coupling practical in dense instrument layouts. Straight versions are available in PTFE or POM; the present size is specified as POM for the 1,6 × 3,2 mm tubing range. Parts from manufacturer Bohlender ship in packs of 3 pieces and carry a net weight of 0,001 kg. Within fittings assemblies these mini couplings provide secure in-line polymer joins when hollow screws of the matching UNF thread are used. The straight form supports simple through connections without additional branches, which helps when routing analytical fluid lines in chromatography accessory sets and related manifold or stand connector applications.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about BOLA Miniature Couplings, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm POLYAMID, straight
What is this article?
BOLA Miniature Couplings, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm POLYAMID, straight 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.
