Method UHP Nitrogen gas 0.75 cubic meter with flow meter and two gauges

[Greenberg]

The barbed outlet should be slightly larger than the tubing. Just take a measurement of the inside diameter of the tubing, and purchase an outlet slightly larger.

1. I will use the mask you recommended which is High concentration mask. Just worried of if atmosphere air enters from the sides of the mask Incase of sudden movement.

2. flow meter outer fitting need to fit the oxygen tube. What size of outer fitting should I ask for ?

If I show them my oxygen tube sample they will deny selling me the product.

Greenberg can you advice me on the outer fitting of the flow meter to attach oxygen tube. How to select the right fitting. Whether it should be threaded or plain ? What should be the size, thickness of the outer fitting ?

Can you share the dimensions of the tube of high concentration mask ?

The outlet fitting should be barbed. I do not know the diameter of your oxygen tube; as mentioned earlier, take a measurement of it and then purchase a fitting slightly larger. I do not think your retailer will take issue of your purchase, just say that you need it to homebrew beer. They would understand.
