Tnisesm Silicone Vacuum Hose Kit 134-Piece — Six 6.6ft Reinforced Hoses, 128 Heat-Resistant Connectors for Automotive

The Tnisesm 134-piece silicone vacuum hose kit supplies high-temperature, high-pressure vacuum tubing and a wide range of nylon connectors for automotive, marine, and workshop vacuum routing projects.

This kit bundles six different inner-diameter silicone hoses (each 6.6 ft long) with 12 connector types and 128 connector pieces so you can mix, match and repair vacuum, coolant bypass, intake or accessory lines without hunting for individual parts. The hoses are reinforced silicone that tolerates extreme temperatures and the nylon connectors resist heat, making the set suitable for routing air or water in engine bays, custom fabrication and general-purpose workshop tasks. The package prioritizes versatility: multiple diameters cover older cars, modern engines and small equipment, while varied fittings simplify changes and splices on the bench or under the hood.

How do these hoses handle heat and pressure in engine compartments?

The tubing is reinforced silicone rated for a broad temperature range and tested for practical working pressure and burst thresholds. That combination helps the lines resist softening, cracking and collapse when exposed to high under-hood temperatures and pressure fluctuations during operation.

• Temperature range: -76°F to 392°F (-60°C to 200°C)
• Working pressure: 43 PSI; burst pressure up to 100 PSI at high temperature and 130 PSI at room temperature
• Wall thickness ~3 mm for kink resistance under vacuum
• Heat-resistant nylon 66 connectors rated to 240°C (460°F)

Which sizes and connectors are included for fitting different machines?

The kit covers the most common small-diameter vacuum and coolant routing needs with six silicone inner diameters and a broad assortment of connector types so you can build straight runs, branches or repairs without extra parts. It’s designed to match both metric and imperial-style applications frequently found on older vehicles and custom builds.

• Hose inner diameters: 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm (each 6.6 ft long)
• Outer diameters: 7, 10, 11, 12, 14, 16 mm respectively for clamp compatibility
• 12 connector sizes/types with 128 connector pieces for tees, elbows and straight joins
• Suitable for splicing, branching, and length adjustments without soldering or gluing

What jobs is this kit best used for in the shop or at home?

Because the hoses carry air and water only, this set excels at intake plumbing, coolant bypass lines, vacuum lines to sensors and actuators, and DIY intercooler or radiator modifications where silicone’s flexibility and heat tolerance are helpful. It’s not intended for fuel, oil or aggressive chemical transfer—stick to air and water uses.

• Vacuum line replacement for sensors, brake boosters and controllers
• Custom intake/trumpet plumbing, intercooler resonators, small turbo piping (air only)
• Cooling bypasses, heater core feeds, small radiator or water-transfer lines
• Marine and light industrial air or water routing (non-fuel applications)

How does the kit save time and money compared to buying parts separately?

By providing multiple diameters and many connectors in one package, the kit reduces downtime and prevents multiple orders when troubleshooting or fabricating. It lets you cut custom lengths on the fly and test different fittings without delay, which is especially useful during diagnostics and prototype builds.

• One purchase covers six common hose sizes—no repeated shopping trips
• High quantity of connectors avoids single-use shortages during repairs
• Reusable nylon fittings simplify swapping and reconfiguration
• Cuts and custom lengths let you adapt hoses to unique layouts immediately

Who is this for: Mechanics, DIY enthusiasts, fabricators and boat owners who need durable, heat-resistant vacuum and water hoses for routing, repair or prototype builds will find this Tnisesm kit useful. It’s ideal for anyone wanting an all-in-one set that covers common hose diameters and connector types for engine bays, garage projects and small industrial applications — provided the lines are used for air or water only and not for fuel or oil transfer.
