House of TubingTM high quality pure silicone hose. 6 MM internal diameter.
Our vacuum hose has thick walls that can withstand high pressure, make tight bends without collapsing, and has an airtight fit. When sized correctly our vacuum hoses do not require clamps or zip ties, even when on the pressure side of a forced induction system. Vacuum hose should have an airtight fit on the nipple it connects. Never use silicone hose for fuel, oil, or any
petroleum base products.
