hi, i cant seem to have access to regular brew tubing lines, so i just went to my lical shop for ubing and the have 2 options>
1. 1/4 inch ID 1/2 OD vynyl reinforced tubing, this its food grade FDA and for a max 250 psi operation
2. 1/4 inch ID 3/8 OD Parker Parflex Polypropylene Tubing NSF 51 White this its for 150 psi operation FDA NSF-51 NSF-61 type 1.
the vynyl seem thicker but i seem somehow flexible and smell like pastic, the poly seem thinner but a lot more rigid, also its odorless.
so im wondering if this options are good specially the poly tubing, for my keezer, or i should buy from a hombrew store some beer lines, that might be expensive due the shipping cost to my country, so i had to try locally first
