Nozzle Tube Assembly, this is the insert assembly that is used for the small 8 mm round valves on a Dr. Oligo 48 for all the reagents except for amidites.
This consists of a 1.0-inch-long piece of 1/16 inch OD Orange Teflon tube with a 1.2-inch-long stainless steel tube inserted into the Teflon tube. Also, includes a ferrule.
When a nozzle tube becomes damaged or clogged on the Dr. Oligo 48 that uses 8 mm round valves, this part usually will fix the issue. Using this part requires that you use the old tub nut with stainless steel insert.
