EVIL ENERGY Silicone Vacuum Tubing 5/16 (8mm) 10ft Black — 130 PSI, High-Temp

This 10-foot length of black silicone tubing combines flexible, FDA-compliant material with thick walls to resist collapse, abrasion and high temperatures. Built to withstand a wide temperature band and strong working pressures, the hose is suited for automotive vacuum routing, turbo and boost applications, and any system that needs a resilient vacuum line with predictable performance.

How does this silicone vacuum hose hold up to temperature and pressure?

The tubing uses pure silicone that tolerates extreme temperatures from -40°F to 428°F (-40°C to 220°C) without losing flexibility. It maintains structural integrity under both vacuum and positive pressure, with a clear margin between working and burst ratings.

• Working pressure: 43 PSI for continuous service.
• Burst pressure: up to 130 PSI at room temperature, 100 PSI at elevated temperatures.
• Stable across a broad -40°F to 428°F temperature range.
• 3 mm wall thickness resists collapse under vacuum.

Will the 5/16" (8mm) size fit common automotive vacuum and boost systems?

The inner diameter (8mm or 5/16") matches many stock and aftermarket vacuum fittings used on engines, turbos, and boost controllers. With a 14mm outer diameter, it provides enough thickness for clamps while remaining compatible with standard connectors and barbs.

• Inner diameter: 8mm (5/16") for widespread fitment.
• Outer diameter: 14mm for secure clamping and hose ends.
• 10-foot length gives flexibility to route multiple lines or cut custom lengths.

What makes this hose durable and suitable for repeated service?

Durability comes from the combination of a thick silicone wall and food-grade pure silicone compound that resists aging, ozone, and oil splash. The 3 mm wall thickness prevents collapse under vacuum and helps the hose hold its shape when clamped or routed in tight spaces.

• 3 mm wall thickness prevents pinching and collapse.
• FDA-compliant silicone resists hardening and cracking over time.
• Black finish conceals grime and resists UV degradation.

How easy is it to install and maintain this tubing?

The hose is simple to cut to length and fits common barbed fittings and vacuum components with clamp or spring clips. Cleanup is straightforward because silicone resists sticking and can be wiped or soaked when needed.

• 10 ft (3.05 m) continuous length for versatile routing.
• Cut cleanly with scissors or a hose cutter for custom runs.
• Compatible with clamps, spring clips, and barbed fittings.

Who is this for: This EVIL ENERGY silicone vacuum tubing is aimed at mechanics, tuners, DIY automotive enthusiasts, and anyone needing a dependable vacuum or boost line that endures high heat and pressure. It’s also a solid option for prototype builders, hobbyists, and light industrial uses where a resilient, food-grade silicone hose is required.
