MooiYrs Silicone Vacuum Hose Kit — 6 Sizes 6.6ft, 130PCS Connectors, 130 PSI, 3mm Wall

This kit bundles flexible, high-temperature silicone vacuum lines and a wide assortment of connectors so you can rebuild, reroute or prototype vacuum and coolant plumbing quickly. The hoses are sized from 1/8" to 3/8" inner diameter and come in long 6.6 ft lengths, making cuts and custom runs easy while maintaining a thicker 3mm wall for durability. Designed for hobbyists, mechanics, fabricators and marine use, the set targets leak-free performance where heat and pressure tolerance matter.

How does this kit stand up to heat, pressure and engine conditions?

The tubing is made from premium silicone with a rated working range from -76°F to 392°F and a maximum pressure listed at 130 PSI. That wide temperature span protects against hardening in cold weather and softening in hot engine bays, while the thicker 3mm wall adds puncture and abrasion resistance. Use it for vacuum lines, coolant bypasses, boost reference lines and general-purpose fluid or air routing where reliability counts.

• Temperature tolerance: -76°F to 392°F for stable performance in varied climates
• Maximum pressure: rated to 130 PSI for durable operation
• Wall thickness: 3mm reduces risk of pinholes and kinking
• Material: high-quality silicone resists oil, coolant and UV exposure

What sizes and connector options are included for custom plumbing?

The package provides six inner-diameter tubing sizes—1/8", 5/32", 3/16", 1/4", 5/16" and 3/8"—each in a 6.6 ft length, plus a broad assortment of 12 connector types that total 130 pieces. That selection covers most common vacuum and low-pressure coolant needs for cars, motorcycles, boats and small engines, letting you match hose ID to fittings and splice or branch lines easily.

• Tubing IDs: 3mm (1/8"), 4mm (5/32"), 5mm (3/16"), 6mm (1/4"), 8mm (5/16"), 10mm (3/8") — each 6.6 ft long
• Connectors: straight joins, T-joins, elbows and reducers for flexible routing
• Total count: 130 pieces for multiple repairs or fabrications
• Cut-to-length friendly: silicone is easy to trim and seal with clamps

How easy is it to install and adapt for custom projects?

Silicone hose is soft enough to bend around tight engine-bay paths but sturdy enough to hold shape when clamped, making on-vehicle installation straightforward. The long lengths let you measure and cut precisely to your layout, and the connector variety minimizes additional purchases. For secure joints, use stainless clamps or crimp-style clips suitable for silicone tubing.

• Flexible and bendable for tight installations without kinking
• Cut-to-fit lengths reduce waste and allow custom routing
• Works for vacuum, intake plumbing, coolant bypasses and marine lines
• Pair with worm-drive or ear clamps for reliable sealing

Who is this for? If you are a DIY mechanic, tuner, marine technician, small-engine repairer or fabrication hobbyist who needs dependable silicone vacuum and low-pressure lines, this MooiYrs kit supplies a wide range of sizes and connectors to complete repairs and custom setups without multiple trips to the parts store. It’s especially useful when you need longer continuous runs, thicker-walled hose for tougher environments, and a large connector assortment for branching, reducing or joining lines.
