1/4 in NPT Female to 1/4 in Barbed Female Converter Attached to N2 nozzles in lab
I added three 1/4" NPT Female to 1/4" Barbed Female Converters to the N2 nozzles in the B110 fume hood, West of the North clean rooms in B111A, and North of the mobile clean rooms in B111B. The 1/4" barbed female end should fit the 1/4" ID tubing I previously bought to back fill the LFC and RbQ Vacuum Chamber. We might need to split the nozzle off in B111A for our multiple vacuum chambers. To tighten the converter, I used a 9/16" and 17 mm wrench. I didn't crank it too hard. In the B110 fume hood, the air velocity is much higher now, which should allow for better solvent removal.

We attached a 1/4" ID hose from the N2 nozzle in B111B to the LFC up-to-air valve. We put it through one of the inner gaps for cables/cubes in the mobile clean rooms. We purged the tube with N2 briefly before attaching it to the LFC. We used hose clamps to attach the hose; the hose clamp on the barbed nozzle was not particularly helpful as the hose is pretty secure without it.
