Description
BOLA screw-in connectors UNF are PTFE transition pieces that combine a GL14 laboratory fitting thread with an external UNF 1/4'' 28G screw-in thread for direct mounting into instruments and couplings. The GL14 side is intended for hard-walled tubes and hoses used with BOLA laboratory screw fittings, while the UNF 1/4'' 28G male thread screws into devices or fittings that have a matching internal UNF 1/4'' 28G thread. This version is sized for tubing with inner diameter × outer diameter 0,8 × 1,6 mm and provides a through-bore of 0,8 mm for low-volume fluid paths. Overall length is 39 mm, keeping the connector short for tight instrument panels and compact chromatography or process modules. The body is machined from polytetrafluoroethylene (PTFE) for chemical resistance in laboratory fluid systems and is offered by manufacturer Bohlender as a single piece with a net weight of 0,0094 kg. Typical use is the leak-tight coupling of small-bore hard tubing to UNF-threaded ports on pumps, valves, detectors and other laboratory apparatus where an all-PTFE wetted connection is preferred.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about BOLA UNF Screw-in Tube Fittings, 0,8x1,6mm / GL14 - UNF 1/4''28G PTFE, 1x GL 14
What is this article?
BOLA UNF Screw-in Tube Fittings, 0,8x1,6mm / GL14 - UNF 1/4''28G PTFE, 1x GL 14 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.
