Oily Bits used to sell two types, black and clear, wire reinforced.
Tried the black type and it most certainly wasn't bio proof, sweating from day one and it eventually delaminated.
Tried the clear reinforced type and it's been just fine for many years.
I think this was the stuff, but they list silly big diameters, only sell full coils and don't list the price.
Not too much help, sorry.
