EVIL ENERGY silicone vacuum tubing hose kit 4×5ft (4,6,8,12.7mm) Black — heat‑resistant, 130 PSI

EVIL ENERGY's silicone vacuum tubing kit supplies four 5 ft (1.5 m) tubes in 4mm, 6mm, 8mm and 12.7mm for durable, heat-resistant vacuum and boost line use.

This kit bundles four lengths of premium silicone vacuum hose engineered for automotive and general-purpose vacuum applications. Each 5-foot tube is made from food-grade, FDA-compliant silicone with a 3 mm wall to resist collapse under vacuum. With wide temperature tolerance and high burst pressure, these hoses are suited to turbo vacuum, boost control, and other systems where flexibility, chemical resistance and heat stability matter.

How tough are these hoses for high-temperature engine bays?

The silicone construction withstands extreme heat and cold, keeping flexibility and strength from -40°F to 428°F (-40°C to 220°C). At room temperature the hoses resist burst up to 130 PSI and maintain a working pressure of 43 PSI, so they’re built to tolerate transient pressure spikes and hot engine environments.

• Temperature range: -40°F to 428°F (-40°C to 220°C)
• Burst pressure: 130 PSI at room temperature; 100 PSI at high temperature
• Working pressure: 43 PSI for routine vacuum/boost tasks
• 3 mm wall thickness prevents collapse under vacuum loads

Which sizes are included and what applications fit each size?

The kit contains four 5 ft (1.5 m) lengths in common vacuum diameters: 5/32" (4 mm), 1/4" (6 mm), 5/16" (8 mm), and 1/2" (12.7 mm). That range covers small sensor lines, PCV/vacuum routing, boost control plumbing and larger manifold or reservoir connections.

• 4 mm (5/32") — ideal for vacuum sensor tubing and small fittings
• 6 mm (1/4") — common for PCV lines and general vacuum routing
• 8 mm (5/16") — fits many boost controller and turbo vacuum ports
• 12.7 mm (1/2") — suitable for larger manifold taps and reservoir lines

Are these hoses safe for fuel or food contact and how durable is the material?

The hoses are manufactured from FDA-compliant food-grade silicone, which offers strong chemical resistance and inertness for many uses. While silicone resists many fluids and maintains integrity in harsh environments, always verify compatibility with specific fuels or solvents before prolonged exposure.

• Material: pure silicone, FDA-compliant food grade
• Chemical resilience: inert to many automotive fluids; check for specialty chemicals
• Flexible and tear-resistant with consistent wall thickness
• Easy to cut and route for custom installations

How simple is installation and what should I prepare?

Installation is straightforward: measure and trim to length, slide over fittings, then clamp as required. The silicone’s flexibility makes routing around tight bends easy, but use appropriate clamps or hose fittings at pressure points to ensure leak-free operation.

• Each tube comes in 5 ft (1.5 m) lengths for flexible routing
• Cut cleanly with a sharp blade for burr-free ends
• Use worm-drive clamps, spring clips, or barbed fittings where needed
• Confirm inner diameter matches your fittings before final assembly

Who is this for: EVIL ENERGY’s silicone vacuum tubing kit is aimed at DIY mechanics, tuners, and maintenance professionals who need reliable, heat-resistant vacuum and boost lines. It’s a practical choice for engine bay upgrades, turbo plumbing, vacuum repairs, laboratory setups, or any project calling for flexible silicone tubes in the sizes included. If you need a ready set of commonly used diameters with strong temperature tolerance and crush resistance, this kit covers those bases.
