MooiYrs Silicone Vacuum Hose Kit 130PC (5 ft Hoses) — 6 IDs, High‑Temp 130 PSI Durable Engine & Boost Lines

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

This kit supplies six common inner diameters of silicone hose (from 1/8" to 3/8") with 5-foot lengths, plus a wide assortment of connectors to replace old vacuum lines, build custom manifolds, or repair heater and turbo plumbing. The hoses are engineered for heat resistance and durability without hardening or collapsing, and the connectors let you create reliable joints for vacuum, coolant, or air-routing chores.

What makes these hoses suitable for engine bays and high-heat zones?

The hoses are molded from premium silicone rated for continuous temperatures from -76°F to 392°F and a working pressure up to 130 PSI. That combination resists aging, cracking, and softening that typical rubber can suffer under under-hood heat and chemical exposure.

• High-temperature silicone construction for stable performance.
• 130 PSI max working pressure for vacuum and boosted applications.
• 3mm wall thickness for strength and resistance to kinking.
• Wide temperature range for cold starts and hot operation.

How easy is it to fit and customize this kit for different vehicles?

Each hose comes in 5-foot lengths that are flexible and easy to trim, so you can cut exact runs for routing in tight engine compartments. The 130-piece connector set includes multiple diameters and joint types to match a variety of factory fittings and custom assemblies.

• Six inner diameters: 1/8", 5/32", 3/16", 1/4", 5/16", 3/8" for broad compatibility.
• Cut-to-length flexibility for precise routing and clean finishes.
• Assorted connectors simplify splicing, branching, and sealing lines.
• Works with vacuum, boost, intake, and coolant bypass lines.

Will these hoses hold up under pressure and long-term use?

The kit is designed with a beefy 3mm wall and a documented 130 PSI rating for reliable service in boosted or pressurized circuits. Silicone's resistance to oils, coolants, and ozone helps prevent common failure modes so installations stay leak-free longer than many standard rubber replacements.

• Thicker walls to resist collapse and abrasion in tight bends.
• Material resists oil, coolant, and ozone exposure for longevity.
• Connector assortment reduces the need for improvised joins that can leak.
• Consistent internal diameters help maintain flow and vacuum integrity.

What practical jobs can this kit handle right away?

From routine vacuum line replacement to custom turbo plumbing or marine engine maintenance, the kit covers most small-bore fluid and air routing tasks. Its versatility also makes it a go-to for hobbyists fabricating intercooler piping, PCV systems, heater hoses, and other under-hood modifications.

• Replace cracked factory vacuum and PCV lines quickly.
• Fabricate custom intake or intercooler plumbing in DIY builds.
• Use in marine and industrial small-diameter fluid runs.
• Temporary or permanent repairs for cooling bypasses and vents.

Who is this for: MooiYrs Silicone Vacuum Hose Kit is aimed at mechanics, tuners, boat owners, and DIY enthusiasts who need a robust, all-purpose assortment of silicone tubing and fittings. If you work on engines, build custom plumbing, or want a ready stock of reliable vacuum and low-diameter hoses for repairs and projects, this kit provides the variety, temperature tolerance, and connector selection to get professional-feeling results without sourcing parts individually.
