Description
PTFE fitting, 4 mm OD, white is a laboratory connector engineered for secure, airtight attachment of HPLC capillaries. Made from chemically resistant PTFE and equipped with an integrated ferrule, it ensures reliable sealing when joining tubing to Safety Caps and Safety Waste Caps. The fitting features a UNF 5/16''-24 thread and is sized for 4,0 mm outer diameter tubing. This white PTFE fitting from manufacturer SCAT forms part of a modular range offered in seven diameters and eight colours, all sharing the integrated-ferrule construction for consistent performance. Compatible with the full SCAT Safety Cap and Safety Waste Cap systems, it supports safe solvent delivery and waste collection in analytical and preparative chromatography. The inert polymer resists common HPLC solvents and maintains integrity under routine laboratory conditions. Supplied as one piece, the fitting installs quickly without additional ferrules beyond standard finger-tight assembly on compatible ports.

Questions about PTFE fitting, 4,0 mm OD, white
What is this article?
PTFE fitting, 4,0 mm OD, white is the article on this page. Luminix Health distributes SCAT 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.
