EVIL ENERGY Silicone Vacuum Tubing Kit 6-Pack 5ft Hoses (3–10mm) – Food-Grade, 130 PSI, Heat-Resistant

EVIL ENERGY silicone vacuum tubing kit contains six 5-foot black hoses in graduated inner diameters for reliable air and water transfer up to 130 PSI at room temperature.

This kit bundles six lengths of food-grade, FDA-compliant silicone vacuum hose in the most commonly used inner diameters, giving you a ready set for automotive vacuum lines, turbo boost plumbing, A/C vacuum work, lab setups, and hobby plumbing. Each hose features a 3 mm wall to resist collapse under vacuum and a broad temperature range (-40°F to 428°F / -40°C to 220°C), so the same hoses can be used for cold-weather starts or high-heat applications. The hoses are intended for air and water only — they’re not rated for natural gas or oil transport.

What sizes are included and why those diameters matter?

The kit contains six 5-foot (1.5 m) hoses sized 1/8" (3 mm), 5/32" (4 mm), 3/16" (5 mm), 1/4" (6 mm), 5/16" (8 mm), and 3/8" (10 mm) inner diameter. These cover most small-vacuum and boost plumbing needs so you won’t need to splice or restrict fittings to match common ports. Using the correct diameter improves flow and prevents undue stress on fittings.

• Six lengths, each 5 ft for flexibility and spare length.
• Covers tiny sensor lines up to moderate boost/vent plumbing.
• Prevents mismatched fittings and unnecessary adapters.

How durable and heat-resistant are these silicone hoses?

Each hose is made of pure silicone rated to withstand -40°F to 428°F (-40°C to 220°C) and uses a 3 mm wall thickness to resist collapse under vacuum. Working pressure is 43 PSI with burst ratings up to 100 PSI at high temperature and 130 PSI at room temperature. That combination of wall thickness and temperature tolerance gives dependable performance in engine bays and heated environments.

• 3 mm wall prevents kinking and collapse under vacuum.
• 43 PSI working pressure for routine vacuum and boost tasks.
• Burst-rated up to 130 PSI at room temperature for safety margin.

What are the approved uses and important limitations?

These hoses are intended for transferring air and water only; they are not suitable for natural gas, fuel, oil, or other hydrocarbon liquids. Typical approved uses include automotive A/C vacuum service lines, vacuum sensor lines, turbo vacuum/boost plumbing, lab pneumatic tubing, aquarium plumbing, and hobby projects. Always verify chemical compatibility before exposing silicone to solvents or fuels.

• Recommended: automotive vacuum lines, boost lines, A/C service, lab air, hobby plumbing.
• Not recommended: natural gas, gasoline, oil, or solvent transfer.
• Food-grade silicone suitable for non-hazardous water and air contact.

How does this kit simplify repairs and installations?

Having six common diameters ready in equal 5-foot lengths reduces downtime and guesswork when swapping lines or building assemblies. The black silicone is flexible for routing, yet firm enough to hold on to barbed fittings and clamps, so connections stay secure under vacuum and light positive pressure. The variety eliminates frequent trips to the store for the right size.

• Equal lengths for consistent spares and replacements.
• Flexible but stable material for neat routing and clamp retention.
• Wide temperature range reduces need for multiple material types.

Who is this for: The EVIL ENERGY silicone vacuum tubing kit is designed for mechanics, DIY automotive enthusiasts, hobbyists, lab technicians, and anyone who needs reliable air or water transfer lines in multiple sizes. It’s especially useful when you need durable, flexible hoses that tolerate a wide temperature range and resist collapse under vacuum — provided you do not intend to carry fuel or gas through these lines.
