MooiYrs Silicone Vacuum Hose Kit 130PC Blue 6 IDs 5ft Tubing with Connectors — High Temp, 3mm Wall, 130 PSI

MooiYrs Silicone Vacuum Hose Kit is a complete 130-piece set of high-temperature, thick-walled blue silicone tubing and connectors designed for automotive, marine, and DIY engine bay vacuum and coolant routing.

This kit provides six inner-diameter options of flexible silicone hose, long 5-foot runs, and a wide assortment of connectors so you can replace brittle factory vacuum lines, build custom plumbing for turbo or intercooler work, or route coolant and air lines without resorting to short, flimsy sections. The hoses are rated for high pressure and wide temperature extremes, offering a reliable alternative to standard rubber lines for long-term projects and performance applications.

What is included and how many pieces will I receive?

The set includes six different inner-diameter hoses and a variety of connectors adding up to 130 pieces total. Each hose size is supplied in a 5-foot length so you can cut custom runs without needing many splices.

• ID 3mm (1/8") — OD 9mm — 5 ft
• ID 4mm (5/32") — OD 10mm — 5 ft
• ID 5mm (3/16") — OD 11mm — 5 ft
• ID 6mm (1/4") — OD 12mm — 5 ft
• ID 8mm (5/16") — OD 14mm — 5 ft
• ID 10mm (3/8") — OD 16mm — 5 ft
• Assorted vacuum connectors and fittings included — total kit count: 130 pieces

How tough are these hoses and what conditions can they handle?

MooiYrs hoses are manufactured from premium silicone with a reinforced 3mm wall thickness for durability and leak resistance. They withstand wide temperature ranges and hold up under moderate pressure, making them suitable for engine bay use and light pressurized lines.

• Temperature range: -76°F to 392°F (-60°C to 200°C)
• Maximum working pressure: up to 130 PSI (material rating)
• Thick 3mm walls resist kinking, abrasion, and premature collapse
• Flexible construction allows easy bending and routing in tight spaces

Can I cut and install these hoses myself — what tools or tips help?

Yes — the silicone tubing is easy to trim with common tools and installs with the included connectors or standard clamps. For reliable joints, use a sharp tubing cutter, push fittings fully onto the hose, and secure with hose clamps where required.

• Cut with a rotary tubing cutter, sharp utility knife, or fine-tooth saw for clean ends
• Use the provided vacuum connectors for quick factory-style joints
• Fit clamps (worm-drive or spring) over larger ID runs for pressurized applications
• Test assembled lines for leaks before returning to full service

Will this kit work for both vacuum and coolant routing?

The silicone material is compatible with air, vacuum, and many coolant environments, but selection of hose size and secure fittings is important for liquid service. For permanent coolant plumbing, pair the correct ID hose with corrosion-resistant clamps and check for chemical compatibility with your specific fluids.

• Suitable for vacuum lines, breather hoses, and low-to-moderate pressure coolant or intercooler plumbing
• Not intended as a direct substitute for high-pressure radiator hoses without proper clamps and fittings
• Verify compatibility if using specialty fluids (additives, fuels, solvents)

Who this kit is for: DIY mechanics, restorers, custom builders, tuners and marine technicians who need long, flexible runs of reliable silicone hose in multiple diameters. If you’re replacing brittle vacuum lines, fabricating intake or intercooler plumbing, or assembling a custom manifold of hoses and connectors, this MooiYrs kit supplies the lengths, sizes, and fittings to finish the job cleanly and with fewer splices.
