Can I use my 0.25mm ID column with a Press-Tight® Connector?

Press-Tight® Connectors can be used with any fused silica column that has an OD of 0.33 to 0.74mm. The nominal OD of Restek 0.18mm and 0.25mm ID fused silica columns is 0.37mm; therefore, they are compatible with Press-Tight® Connectors.
