TSIEBRV Silicone Vacuum Hose Kit — 6x 4.9ft Hoses (1/8"–3/8" IDs) with 64 Connectors & Cutter, High-Temp Durable

TSIEBRV 6PCS Silicone Vacuum Lines Automotive kit is a complete replacement set of durable silicone vacuum hoses, 64 nylon connectors, and a cutter for repairing and upgrading vehicle vacuum systems. This kit is built to replace brittle or leaking vacuum tubing under the hood and to support performance-minded hose upgrades. It includes six continuous 4.9 ft silicone hoses in common inner diameters, a selection of universal nylon connectors, and a compact tube cutter — everything needed to rebuild vacuum lines for engine bays, HVAC systems, and non-pressurized water routes. The hoses resist high temperatures, cold weather, and typical engine-bay wear while offering consistent inner dimensions for secure sealing.

Which hose sizes are included and why those diameters matter?

The set contains six different inside diameters to match the variety of vacuum fittings used across modern and older vehicles. Using the correct ID prevents leaks and preserves system pressures for sensors, actuators, and vacuum-operated components.

• 1/8" (ID) — thin runs and small fittings
• 5/32" (ID) — intermediate small connections
• 3/16" (ID) — common vacuum line size
• 1/4" (ID) — typical for many HVAC and engine lines
• 5/16" (ID) — larger vacuum or return lines
• 3/8" (ID) — high-flow vacuum or water routing

How does the kit ensure a leak-free connection?

Hoses are manufactured from thickened silicone with smooth, even walls and tightly controlled dimensions so fittings seat properly. The included nylon connectors offer robust mating points that, when cut and installed correctly, form a secure seal to maintain system integrity.

• Precision inner diameters for snug fit with fittings
• 64 nylon connectors for tees, elbows, and couplings
• Silicone material resists deformation and holds clamp tension

Can these hoses handle engine temperatures and pressures?

Yes — the silicone hoses are rated to operate across extreme temperatures and handle typical vacuum system pressures encountered in automotive use. They are suitable for normal vacuum and air/water conveying applications but are not designed for fuel, engine oil, or coolant transfer.

• Temperature range: -40°F to 428°F
• Working pressure up to 43 PSI; burst tested to ~130 PSI (room temp)
• High heat resistance reduces hardening and cracking over time

What tools and parts come in the package for installation?

The kit is ready for hands-on repairs: long continuous lengths of each hose size let you route runs without many joints, while the cutter and many connectors let you tailor the layout. Using the cutter yields clean ends for better sealing around connectors and clamps.

• Six 4.9 ft silicone hoses (one per listed ID)
• 64 universal nylon connectors for custom routing
• One compact tube cutter to make precise cuts

Who is this for This TSIEBRV silicone vacuum hose kit is ideal for mechanics, restoration hobbyists, DIY car owners, and performance tuners who need a reliable set of vacuum and air lines. Choose this kit when you want long replacement runs in multiple sizes, plenty of connectors for branching or repairs, and a purpose-made cutter to finish neat, leak-resistant connections. Note: do not use these hoses for fuel, engine oil, or coolant lines.

FAQ

Q: Are these hoses safe for coolant or fuel?

A: No. The hoses are intended only for conveying air or water; they must not be used for fuel, engine oil, or coolant.

Q: How long is each hose and can I cut them to size?

A: Each hose is 4.9 ft long and the included tube cutter lets you trim lengths cleanly for custom routing.
