We supply fittings by Agilent Technologies, Upchurch, Vici Valco, and other manufacturers. We offer fittings of different materials like PVDF, PEEK and Keel-F. PEEK is usually the most resistant material which is suitable for all organic and anorganic solvents and is mostly acid- and base stable. The ferrule simply slides over any tubing to its required position, while the nut is finger tightened. The unique double ended ferrule design seals at to points to prevent leaks.
