2 13/16" Tubing | McMaster-Carr

Strengthened with yarn, this hose handles high-pressure vacuum and suction without getting kinked or crushed. Also called brewer's and vintner's hose, it's FDA compliant and 3-A certified, so it's safe to use with wet food and drinks. However, you shouldn't use it with oily food. It's made of chlorobutyl, which means it stands up to frequent hot water and chemical cleanings. Since it's interior is smooth, food won't get caught or build up inside the hose. This hose has an EPDM cover that won't tear, so you can drag it across shop floors. It's not for continuous steam service.
