EVIL ENERGY Silicone Vacuum Tubing Kit 4 Sizes 10ft Black — 130 PSI, High-Temp Food-Grade

EVIL ENERGY's silicone vacuum tubing kit supplies four 10-foot vacuum hoses in 4mm, 6mm, 8mm and 12.7mm diameters built for high-temperature and high-pressure automotive use.

This kit brings durable, food-grade silicone vacuum lines designed for engines, turbo systems, boost controls, and workshop plumbing. Each hose has a 3mm wall thickness to resist collapsing under vacuum and offers wide operating temperatures from -40°F to 428°F, making it suitable for under-hood heat as well as colder climates. With tested burst pressure up to 130 PSI at room temperature and a 43 PSI working pressure rating, the set is tailored for demanding automotive and hobbyist applications where flexibility, chemical resistance, and temperature tolerance matter.

What sizes are included and why those diameters matter?

The kit contains four 10-foot lengths in common vacuum sizes: 5/32" (4mm), 1/4" (6mm), 5/16" (8mm) and 1/2" (12.7mm). These diameters cover most automotive vacuum routing, boost lines, and small pneumatic setups so you won’t need to splice mismatched hoses.

• 5/32" (4mm) for sensor ports and small actuators
• 1/4" (6mm) ideal for vacuum check valves and manifold taps
• 5/16" (8mm) commonly used for boost lines and larger fittings
• 1/2" (12.7mm) for main routing or higher-flow connections

How does the material perform under automotive conditions?

Each hose is molded from FDA-compliant food grade silicone, which offers superior heat stability and resistance to many automotive fluids compared with ordinary rubber. The silicone retains flexibility at low temperatures and resists hardening or cracking from engine heat, extending service life in exposed locations.

• Temperature range: -40°F to 428°F (-40°C to 220°C)
• Food-grade silicone resists oil, coolant vapors, and ozone better than generic rubber
• 3mm wall prevents collapse and abrasion under vacuum

What are the pressure ratings and safe uses for these hoses?

The hoses are rated 43 PSI working pressure with burst ratings tested to 100 PSI at high temperature and up to 130 PSI at room temperature. That makes them reliable for vacuum circuits, boost routing on many turbo applications, and various pneumatic or lab uses where moderate pressure is expected.

• Working pressure: 43 PSI for continuous use
• Burst pressure: 100 PSI at high temperature, 130 PSI at room temperature
• Not intended for extreme high-pressure hydraulic systems

How easy is installation and what fittings work best?

Silicone remains flexible yet firm enough to hold push-fit barb fittings, vacuum caps, and hose clamps without slipping when sized correctly. Trim ends cleanly and use clamps for permanent connections or spring clamps for a removable setup. The consistent inner diameters fit standard barbed and quick-connect vacuum fittings for straightforward swaps or upgrades.

• Cut with a sharp blade for smooth, leak-free ends
• Use barbed fittings sized to the hose inner diameter for secure joints
• Apply small hose clamps where pressure or heat mobility is a concern

Who is this for: This EVIL ENERGY kit suits automotive enthusiasts, tuners, mechanics, and DIY hobbyists needing reliable vacuum and boost lines that tolerate engine bay heat and repeated use. It’s also useful for lab prototyping, small pneumatic projects, and appliance repairs where flexible, temperature-resistant tubing is required. If you need several standard diameters in long, ready-to-cut lengths with a high temperature and pressure margin, this kit provides a practical, all-in-one solution.
