3/8" Silicone Vacuum Hose - High Quality Coupler Material

Our 3/8" silicone vacuum hose delivers the durability your high-performance engine demands. Unlike standard auto parts store alternatives, this hose withstands extreme boost pressures and vacuum conditions without collapsing, peeling, or swelling. Inferior hose can burst under load, causing catastrophic engine damage and throwing off critical reference signals to wastegates and fuel pressure regulators. This premium coupler material maintains integrity across demanding applications, ensuring your boost-referenced systems receive accurate readings. We've standardized on this hose across our shop vehicles because reliability matters when performance is on the line. Ten feet per spool.
