Silicone Vacuum Hose Kit 6PCS 5FT 1/8" 5/32" 3/16" 1/4"

MooiYrs Silicone Vacuum Hose Kit is a complete 6-size set of high-temperature, 130PSI-rated silicone vacuum lines with 12 connector types and 130 pieces for engine, marine, and DIY applications.

This kit supplies durable, flexible silicone tubing in six inner diameters—1/8", 5/32", 3/16", 1/4", 5/16" and 3/8"—each provided in 5-foot lengths, plus a comprehensive selection of connectors to build or repair vacuum, boost and coolant lines. The hoses are constructed from premium silicone with a 3mm wall thickness for resistance to heat, ozone and oil, and they work across a wide temperature range from -76°F to 392°F. Use them for automotive vacuum routing, turbo plumbing touch-ups, marine systems or custom workshop projects where reliable sealing and easy trimming matter.

How durable and heat-resistant are these silicone vacuum hoses?

The hoses are made from high-grade silicone rated for continuous operation from -76°F to 392°F and a maximum working pressure of 130PSI. A 3mm wall thickness improves puncture and crush resistance compared with thin-walled tubing, improving longevity in engine bays and hot spaces.

• Material: high-temperature silicone compound
• Temperature range: -76°F to 392°F
• Wall thickness: 3mm for improved strength
• Max pressure: 130 PSI for vacuum and low-pressure boost use

What sizes and connectors are included in the kit?

This set provides six inner diameters—3mm (1/8"), 4mm (5/32"), 5mm (3/16"), 6mm (1/4"), 8mm (5/16") and 10mm (3/8")—each as a 5-foot length for flexible routing. The package also contains 12 types of vacuum connectors and a total of 130 pieces to cover straight joins, tees, elbows and reducers, so you can adapt tubing to many layouts without hunting additional fittings.

• Six 5-foot silicone tubes, each ID listed above
• 12 connector styles for straight, T, elbow and reducer needs
• Total pieces: 130 for multiple installations or future repairs
• Cut-to-length friendly for customized runs

How easy is it to install or customize the tubing for my car or boat?

The silicone is pliable yet stable, so you can measure, trim and fit lengths with basic tools. It slips over standard vacuum nipples and clamps securely with small hose clamps or OEM-style fittings; the included connectors simplify branching or changes in diameter.

• Cut with scissors or a tubing cutter to desired length
• Fits common vacuum nipples and aftermarket fittings
• Use small clamps or the kit’s connectors for leak-free joints
• Suitable for DIY intake, turbo, intercooler piping repair or routing

Will these hoses resist oil, ozone and engine bay conditions?

Silicone resists ozone, sunlight and many automotive fluids better than ordinary rubber, reducing hardening and cracking over time. While excellent for vacuum, coolant and many intake-related uses, avoid prolonged exposure to concentrated petroleum solvents unless combined with compatible protective measures.

• Good ozone and UV resistance for under-hood service
• Maintains flexibility over wide temperature swings
• Not recommended for continuous contact with strong petroleum solvents
• Well-suited for vacuum, boost, coolant bypass and general routing

Who is this for: The MooiYrs Silicone Vacuum Hose Kit is designed for mechanics, tuners, DIY car builders, marine technicians and hobbyists who need a versatile, long-lasting vacuum and low-pressure hose solution. If you want a ready stock of multiple diameters, reliable heat resistance, and the connectors to assemble complete systems without a parts run, this kit supplies straight lengths and fittings for workshop projects, repairs and custom plumbing tasks.
