Coupling nut for standard beer shank

[sborz22]

Hi All,

I have been trying to get my nitro setup up and running but for the life of me I cannot figure out which coupling nut I need for my faucet and shank. Any help as to where I can buy it is also helpful.

Beer Shank - Chrome Plated 3" x 3/16" bore × 1

Taprite sells piece parts for draft systems. My local home brew store does too.
