YIENFBEV Vacuum Line Kit 84-Piece — 4x12ft Silicone Hoses with 80 Connectors

Complete 84-piece automotive vacuum line kit with four 12-foot silicone hoses in 1/8", 5/32", 3/16" and 1/4" plus 80 assorted connectors for engine bay repair and custom routing.

If you maintain older cars, build performance engines, or perform frequent under-hood repairs, having flexible, heat-resistant vacuum hose and matching fittings on hand saves time and prevents leaks. The YIENFBEV 84 PCS Vacuum Lines Automotive Kit combines long-length silicone tubing in four common inner diameters and a broad assortment of push-fit and barb connectors so you can replace, reroute, or prototype vacuum plumbing quickly without hunting for individual parts.

What sizes and quantities are included?

The kit contains four continuous 12-foot silicone hoses in inner diameters: 1/8", 5/32", 3/16", and 1/4", giving plenty of length for multiple repairs or projects. Also included are 80 connectors covering common vacuum fittings so you can link lines, T off circuits, or plug unused ports.

• Four hoses: each 12 feet (144 in) long — 1/8", 5/32", 3/16", 1/4" ID
• 80 assorted vacuum connectors: elbows, tees, straight joins, and adapters
• Mix designed for engine vacuum, intake routing, and accessory lines

How tough are the silicone hoses in real-world conditions?

These hoses use thicker-walled silicone to resist kinks, cracking, and hardening that rubber lines can suffer over time. The listed working and burst pressures and wide temperature tolerance mean the tubing performs across typical automotive temperature ranges.

• Wall thickness approximately 3 mm for durability and flexibility
• Working pressure ~43 PSI and burst resistance up to ~130 PSI at room temperature
• Temperature range from -40°F to 392°F (-40°C to 200°C)

How easy is installation and customization?

Silicone tubing is simple to trim to length with common tools, and the variety of connectors speeds up fitting without special clamps in many applications. The kit is meant for air and coolant routing in engine bays, marine, and industrial settings, though it is not intended for fuel or oil transport.

• Cut-to-length tubing for one-off layouts or repeated repairs
• Assorted push-fit and barb connectors for quick joins or reroutes
• Use clamps where required; avoid using for gas or oil lines

Will this kit fit vintage vehicles and modern engines?

Yes — the range of inner diameters covers the most common vacuum and breather lines found on classic and contemporary engines. The long hose lengths let you replace entire runs or fabricate new vacuum circuits for turbo, boost control, or emissions components.

• Common diameters for PCV, MAP, vacuum actuators, and breather lines
• Long lengths allow full-routing replacement or multiple smaller repairs
• Compatible with automotive, marine, and many industrial air/water uses

Who is this for: The YIENFBEV 84-piece Vacuum Lines Automotive Kit is geared toward mechanics, restorers, tuners, and DIY enthusiasts who want a reliable, heat-resistant set of vacuum and breather hoses plus a comprehensive selection of connectors. It’s especially useful for workshops that perform frequent vacuum plumbing work, engine swaps, or custom intake and vacuum routing. Remember this kit is for air and water transfer and general vacuum plumbing; do not use these hoses for transporting gasoline or engine oil.
