Description
BOLA Mini screw-in adapters with UNF 1/4'' 28G internal thread are PTFE thread transition pieces for laboratory fluid handling. They provide a changeover from internal UNF 1/4'' 28G to external NPT 1/8'' thread, linking mini-fitting systems with standard NPT ports. The adapter is sized for tubing of 1,6 × 3,2 mm inner × outer diameter (1/16 × 1/8''), with a bore diameter of 1,6 mm for efficient transfer at this tubing scale. Constructed from polytetrafluoroethylene (PTFE), it offers chemical resistance and an inert wetted path for analytical and process applications. Available from manufacturer Bohlender, these compact adapters suit chromatography manifolds, sample preparation lines, and general laboratory plumbing where a durable UNF-to-NPT interface is required. Net weight is 0,003 kg. Supplied as one piece, the mini screw-in adapter fits directly into compatible UNF 1/4'' 28G connections and supports reliable media routing with small-bore PTFE tubing while avoiding metal contact in the fluid stream.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

What is this article?
BOLA Miniature Screw-in Adaptors, UNF 1/4'' 28G, Ø 1,6 x 3,2 mm PTFE, UNF 1/4 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.
