Torque Solution Silicone Vacuum Hose (Black) 3.5mm (1/8in) ID Universal 5ft

This is a 5-foot length of black silicone vacuum hose from Torque Solution. It has an inner diameter of 3.5 millimeters, which is about 1/8 of an inch. This hose is designed for universal applications where a durable, flexible vacuum line is needed.

Silicone is a great material for vacuum lines because it holds up well to heat and won't get brittle over time like rubber hoses can. This means it's less likely to crack or leak, which is important for maintaining proper engine vacuum. The 3.5mm ID is a common size for many vacuum-operated components on various vehicles.
