Vacuum Hose Automotive, 1/8" 5/32" 3/16" 1/4" 5/16" 3/8"ID High Performance Silicone

The ZIQOPGD Silicone Vacuum Hose Set provides a versatile selection of tubing designed to route air and water in automotive, marine, and industrial environments. With six distinct inner diameters ranging from 1/8 inch (3 mm) up to 3/8 inch (10 mm), it offers DIY mechanics and fabricators the right size for custom turbocharger lines, intercooler duct fabrication, and radiator cooling systems.

Each hose is made from high-temperature reinforced silicone with a 3 mm (1/8 inch) wall thickness. This construction prevents twisting and deforming while maintaining flexibility. The material is rated for working pressures up to 43 PSI, with a burst pressure rating of 100 PSI at elevated temperatures and 130 PSI at room temperature. The smooth silicone surface is also free of irritating odors.

Thermal resilience is a notable strong point, as the tubing remains operational across a wide temperature range of -76°F to 392°F (-60°C to 200°C). This allows reliable use throughout the engine compartment in varying weather conditions without degrading from engine bay heat.

Keep in mind that this tubing is strictly meant for air and water lines. It is not suitable for transferring fuel, motor oil, or engine coolant. Additionally, each size comes as a single five-foot length, which may require measuring your project layout in advance if you need longer continuous runs of a single diameter.

Verdict: This six-piece silicone tubing kit is a practical choice for anyone needing reliable, heat-resistant lines for air or water lines in engine bays and custom fabrication projects.

• Material: Reinforced silicone
• Piece Count: 6 hoses
• Length per Hose: 5 feet (1.5 meters)
• Inner Diameters: 3 mm (1/8"), 4 mm (5/32"), 5 mm (3/16"), 6 mm (1/4"), 8 mm (5/16"), 10 mm (3/8")
• Wall Thickness: 3 mm (1/8")

A great fit if you:

• Need a multi-size assortment of silicone lines for air intake or intercooler fabrication
• Require flexible, thick-walled tubing that withstands engine temperatures up to 392°F
• Want ready-to-cut 5-foot lengths for general air or water transfer in automotive or marine settings

Consider something else if you:

• Need plumbing for fuel lines, oil transport, or engine coolant
• Require continuous single-line runs longer than 5 feet in a specific diameter

What sizes are included in the package?
The kit includes 6 hoses, each measuring 5 feet long. The inner diameters are 1/8" (3 mm), 5/32" (4 mm), 3/16" (5 mm), 1/4" (6 mm), 5/16" (8 mm), and 3/8" (10 mm).

Can these hoses be used for fuel or oil lines?
No. These silicone hoses are not suitable for use with fuel, oil, or coolant, and are intended only for general air and water transport.

What are the pressure and temperature limits?
The hoses operate in temperatures from -76°F to 392°F (-60°C to 200°C). They support a working pressure up to 43 PSI, with a burst pressure of 100 PSI at high temperature and 130 PSI at room temperature.
