EVIL ENERGY Silicone Vacuum Tubing Kit — 4pc 5ft (4mm,6mm,8mm,10mm) Black, 130 PSI Max, Heat-Resistant

EVIL ENERGY silicone vacuum tubing kit is a four-piece set of 5 ft food-grade silicone hoses (4mm, 6mm, 8mm, 10mm) engineered for durable vacuum and boost line use up to 130 PSI at room temperature.

This kit supplies four lengths of flexible, high-temperature silicone vacuum hose that are sized for common automotive and small-engine vacuum and boost needs. Made from FDA-compliant pure silicone with a 3mm wall thickness, the hoses resist collapse under vacuum, tolerate a wide temperature range (-40°F to 428°F / -40°C to 220°C), and offer reliable working and burst pressures suitable for turbo plumbing, vacuum actuators, brake boosters, and hobby projects.

How tough are these silicone vacuum hoses under heat and pressure?

The EVIL ENERGY hoses are built for elevated temperatures and repeated pressure cycles. Rated for continuous use across -40°F to 428°F (-40°C to 220°C), they maintain flexibility and structural integrity where rubber lines would harden or crack.

• Working pressure: 43 PSI for routine vacuum/boost applications.
• Burst pressure: up to 130 PSI at room temperature; 100 PSI at high temperature.
• 3mm wall thickness prevents kinking and collapse under vacuum.
• Pure silicone compound resists aging, ozone, and many automotive fluids.

What sizes are included and what do those sizes fit?

The set contains four 5 ft (1.5 m) hoses in commonly used inner diameters: 5/32" (4mm), 1/4" (6mm), 5/16" (8mm), and 3/8" (10mm). Those sizes match standard barb fittings, vacuum ports, and small turbo or boost plumbing found on many cars, motorcycles, and DIY setups.

• 4mm (5/32") for small vacuum lines and sensors.
• 6mm (1/4") for common vacuum actuators and small fittings.
• 8mm (5/16") for intermediate vacuum/boost connections.
• 10mm (3/8") for larger boost lines or vacuum reservoir feeds.

Are these hoses safe for food or chemical exposure?

These hoses are made from FDA-compliant food-grade pure silicone, which is non-toxic and inert for many non-reactive applications. While silicone resists many chemicals, verify compatibility with aggressive fuels or solvents before prolonged exposure.

• FDA-compliant material suitable for incidental food contact and general-purpose use.
• Inert silicone resists aging and ozone better than many rubber compounds.
• Not recommended for sustained contact with strong solvents without testing.
• Easy to clean and flexible across a broad temperature range.

How do I install and secure these vacuum lines correctly?

Installation is straightforward: cut to length with a sharp blade, push over the matching barb or port, and secure with appropriately sized clamps or spring clips for pressure applications. Ensure a snug fit and avoid sharp bends to preserve flow and prevent kinks.

• Slip over barbed fittings or push onto vacuum ports; use clamps for boost service.
• Trim squarely for a clean seal; avoid twisting during installation.
• Maintain gentle bend radii; 3mm wall helps resist pinching under vacuum.
• Inspect periodically for wear or chafing in high-vibration areas.

Who is this for: The EVIL ENERGY 4-piece silicone vacuum tubing kit is aimed at DIY mechanics, tuners, turbo enthusiasts, hobbyists, and anyone needing reliable small-diameter vacuum or boost lines. It suits garage repairs, custom plumbing on engines and turbo systems, prototyping pneumatic circuits, or replacing brittle factory vacuum hoses with a durable, heat-resistant silicone alternative.
