Polyurethane Vac Tubing 1/4in OD 10ft

The Polyurethane Vac Tubing 1/4in OD 10ft from REDHORSE PERFORMANCE is an essential upgrade for any serious engine builder, turbo enthusiast, or street/race car builder managing vacuum-operated systems. Whether you're plumbing a fresh carbureted engine, integrating emissions control components, or routing auxiliary vacuum systems on a custom build, this tubing handles the demands of real-world engine bay environments. Vacuum lines are critical to fuel delivery, brake booster operation, heating controls, and emission systems—making quality tubing non-negotiable for reliability and performance.

Polyurethane construction delivers superior durability compared to OEM rubber tubing, resisting ozone cracking, fuel vapors, and extreme underhood temperatures that degrade standard hoses over time. The 1/4-inch outer diameter (OD) is the industry standard for most vacuum applications, fitting standard metric and SAE vacuum fittings without adapters. REDHORSE PERFORMANCE's formulation maintains flexibility across temperature swings while resisting kinking and collapse under vacuum loads—critical when routing through tight engine bays or around hot components. The 10-foot spool provides ample length for complete vacuum system fabrication, custom layouts, or multiple component routing on larger displacement or modified engine platforms.

This tubing suits carburetor rebuilds, fuel pressure regulator vacuum lines, brake booster plumbing, PCV system upgrades, and custom emissions reroutes on both vintage restorations and modern performance builds. Mechanics and fabricators favor polyurethane for repeatability—it doesn't harden or become brittle after seasons of thermal cycling like aging rubber. Cut to exact lengths needed, crimp or barb-fit standard vacuum fittings, and expect years of maintenance-free operation in street or competition applications. Stock multiple spools for shop inventory, or grab a single roll for your next engine refresh project.
