LF: .5" loc line

[intarsiabox]

AI and Marine Aquaria usually have a good supply of loc-line. If not a number of Canadian on-line stores will have it to you in a few days(maybe a bit longer due to long week-end) Machine tool stores will also carry it as coolant line. I did a quick check and Procut Industrial Supply says they carry it but probably most stores of this type will also.
