Black silicone vacuum hose made to Toyota OEM sizing: 3.5mm inner diameter and 7mm outer diameter.
Replace your split or hardened vacuum hoses with this long lasting silicone hose once and for all. Silicone is tolerant of extreme temperatures, and is not subject to deterioration like the original rubber vacuum hoses. Reliability is sustained because the hoses will stay as new virtually forever regardless of operating environment. You'd be surprised how well an old rig can perform when it's vacuum tight.
Available in different lengths to suit your needs.
