Description
Replacement screw fitting for holder 718966 is a spare connection component for the main column interface on the Column Protection System guard column holder (REF 718966). The fitting is supplied together with one O-ring and is intended to restore a secure mechanical and sealing interface between the analytical column and the guard column holder used in liquid chromatography setups. When original screw fittings wear, deform or lose sealing performance during routine operation, this dedicated replacement allows the holder to remain in service without exchanging the complete assembly. The part is packed as one piece and supports orderly maintenance of chromatography accessory inventories in analytical and research laboratories. Designed for the specified Column Protection System precolumn holder, it aligns with the geometry required for reliable column coupling. This replacement screw fitting from manufacturer Macherey-Nagel is a practical service item for laboratories that keep modular column-protection hardware ready for continuous sample analysis, method development and routine LC workflows where dependable fittings and seals are essential.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about Replacement connector f. holder 718966
What is this article?
Replacement connector f. holder 718966 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC fittings, tubing & inline filters, inside HPLC columns & accessories, in Chromatography equipment.
HPLC fittings and tubing are numbered by bore. A wide bore after the column broadens the peaks. Finger-tight and wrench fittings, and stainless against PEEK, are different pressure ratings. An inline filter is the last screen before the column, and it clogs on purpose so the column does not.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
