bore sizes on nipple shank assemblies equal to ID of tube needed?

[AndrewSF]

Nipple Shank Assembly - 4-1/2" with 3/16" Bore
Draft Beer Nipple Shank Assembly
will this nipple fit a 3/16" ID tube?

Nipple Shank Assembly - 4-1/2" with 1/4" Bore
Draft Beer Nipple Shank Assembly
and, will this nipple fit a 1/4" ID tube?

is that the only difference?

thanks!

Yes, the 3/16 fits 3/16 ID beer line and the 1/4 fits 1/4 ID beer line.

3\16 line will also fit on the 1\4 shank with a little heat and persuasion. 1\4 bore helps with flow to the faucet
