Agilent MS interface column nuts (or transfer line nuts) are manufactured from a softer metal than the transfer line interface. This is to prevent stripping of the transfer line threads and costly repairs. Add a few MS interface column nuts to your next order and keep spares on hand.
Agilent Technologies products are intended for sale/shipment within the US only. International customers should contact their local Agilent Technologies distributor to place orders for Agilent Technologies products.
