Description
Reducing connector UNF 1/4-28 OD 1/8 PFA is a specialised laboratory fitting intended for secure fluid-line transitions in analytical and process setups. The component provides a threaded UNF 1/4-28 interface on one side and an outer-diameter 1/8 connection on the other, enabling reliable diameter reduction within tubing or instrument manifolds. Fabricated from PFA, the connector offers the chemical resistance and thermal stability associated with this fluoropolymer, making it suitable for demanding laboratory environments where inertness toward aggressive media is required. Supplied as a single piece, the reducing connector integrates easily into existing fluid-handling assemblies and supports precise routing of liquids or gases. This item from manufacturer KNF belongs to the broader category of laboratory materials and is identified under UNSPSC classification for laboratory connectors and fittings. Its compact design and standardised thread geometry facilitate straightforward installation without additional adapters in many common laboratory configurations. The PFA construction further ensures low extractables and long-term dimensional stability under typical laboratory operating conditions.

Questions about EINSCHR.VERSCHR-G UNF1/4-28 AD1/8 PFA
What is this article?
EINSCHR.VERSCHR-G UNF1/4-28 AD1/8 PFA is the article on this page. Luminix Health distributes KNF 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.
Which category should I open next?
