Nitrogen/Argon Line, Teflon®

 The 14/20 outer joint in the center of the manifold is designed to suit a rubber septum. The septum maintains syringes in an inert environment, reducing the number of times they're used. The main tube has a 22 mm outside diameter and is available with 10 mm hose connections on the right, left, or both sides. The hose connectors on the delivery ports are 8 mm. There are four ports on each manifold.
