MooiYrs Silicone Vacuum Hose Kit 130PCS — 6 Sizes 6.6ft Lengths, 130PSI Durable Engine Vacuum & Boost Lines

MooiYrs Silicone Vacuum Hose Kit is a complete automotive-grade set of flexible silicone vacuum tubing and connectors designed for engine vacuum, boost, coolant bypasses, and general fluid/air routing.

This kit bundles six ID sizes of high-temperature silicone hose—each length 6.6 feet—with 12 connector types and a total of 130 pieces to replace, reroute, or fabricate vacuum and low-pressure lines. The hoses are engineered with a 3mm wall thickness and rated for up to 130 PSI, making them durable for common automotive, marine, and light industrial routing tasks. The kit's varied diameters and connector assortment let you adapt to multiple fittings, sensors, and plumbing arrangements without buying separate parts.

Which hose sizes and lengths are included, and how do they match my vehicle?

The set includes six inner diameters commonly used in engine bays and shop applications: 3mm (1/8"), 4mm (5/32"), 5mm (3/16"), 6mm (1/4"), 8mm (5/16"), and 10mm (3/8"). Each diameter comes as a continuous 6.6-foot length so you can cut exact segments to fit sensors, vacuum lines, or custom plumbing. These sizes cover EVAP, MAP/vacuum lines, PCV, boost taps, and small coolant bypasses.

• 3mm/1/8" to 10mm/3/8" IDs — six useful common sizes
• Uniform 6.6 ft lengths for multiple runs and spares
• 3mm wall thickness for improved abrasion and pressure durability

How are the connectors organized, and which fittings will I get?

The kit contains 12 connector styles and a total of 130 pieces to let you splice, branch, reduce, or terminate lines without additional adapters. Connectors include straight joins, T-fittings, elbow joins, reducers, barbed ends, and tapered plugs to seal unused ports. That assortment makes it easier to adapt a hose diameter to a sensor port or combine multiple lines for vacuum distribution.

• T-shaped and straight couplers for branching or joining hoses
• Reducers and step connectors for mismatched IDs
• Barbed ends and plugs to attach to sensors or seal ports

What operating conditions and durability can I expect from these silicone hoses?

MooiYrs hoses are formulated to work across a wide temperature range (roughly -76°F to 392°F) and are rated up to 130 PSI in non-pulsating applications. The 3mm wall thickness adds resistance to kinking, abrasion, and moderate vacuum or pressure loads found in automotive and marine systems. Silicone also resists many automotive fluids better than standard rubber, helping maintain pliability and shape over time.

• Temperature tolerance for hot engine bay environments
• 130 PSI nominal rating for low-to-moderate pressure tasks
• Thicker walls to reduce kinks and improve longevity

How easy is it to install and customize these vacuum hoses?

The tubing is highly flexible and can be cut cleanly with scissors or a hose cutter to length, then secured with clamps or spring clips if needed. Silicone's pliability lets you route lines through tight spaces without sharp bends, and the included connector variety reduces the need for extra fittings. Use simple tools and common clamps to complete most installations in a garage or workshop.

• Cut to length with scissors or a hose cutter
• Use clamps or spring clips for secure connections
• Connector assortment reduces additional purchases

Who is this for: The MooiYrs Silicone Vacuum Hose Kit is intended for DIY mechanics, professional technicians, tuners, and hobbyists who need a reliable, ready-to-use selection of vacuum and low-pressure hoses and fittings. It suits routine repairs, custom turbo or intercooler plumbing, intake and coolant bypass modifications, marine rigs, and light industrial uses where silicone’s temperature range and flexibility are an advantage. If you want versatile hose lengths plus a broad connector set in one purchase, this kit covers most common needs.
