From and FDA plant point of view you dont want to pay for anything that will last a long time a 48" X 1" hose with crimped fittings is 200 dollars
For the more afforable stuff that needs to be changed out a lot we use KURI TEC POLYSPRING
The big issue is what pressure is in your system as anything with flex and FDA approvel loses a lot of its rating as pressure increases
WP at 70 F 100 psi
WP at 120 F 70 psi
In are plant the cheep hose became so costly to change most of the stuff is done with RUBBER FAB EPDM LINED which has a 150 PSI rating in 1/2" ID at 70 F
This stuff gets boiling water everyday and is at good as it gets
