Product Description
The screw cap holds the end fitting tight against the column barrel, so a cracked or lost cap means a column that will not seal. These replacement caps fit standard CHROMAFLEX columns and restore a secure, leak-free assembly. They are simple, low-cost spares.
This listing is for Kimble catalog number 420833-0020: Screw Cap For Use With standard 4.8 cm CHROMAFLEX Columns. Caps are available for 1.0, 2.5 and 4.8 cm columns and are sold individually. Thread the cap on by hand over the end fitting, snug it evenly, and avoid overtightening. Check the assembly for leaks at low flow before starting a run. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
