Grainfather Glycol chiller hoses

[G2sat2576]

Does anyone know where i can get a replacement red hose that connects from the Grainfather glycol chiller to the fermenter? I just like to have replacements for everything in case something goes wrong on brew day. I think it may be 3/8 ID and 1/2 OD but i may be incorrect.

I used 5/16" ID. Should be silicone because nylon compatibility with propylene glycol is not good
