OFBAND Silicone Vacuum Hose Kit 6pcs 5ft — Black Automotive Vacuum/Low-Pressure Lines (1/8"–3/8", heat‑resistant)

OFBAND’s 6-piece silicone vacuum hose kit supplies six 4.92-foot (5ft) flexible tubes in common inner diameters to replace or upgrade automotive vacuum, air and water lines.

If you need durable, heat-resistant replacement tubing for brake boosters, vacuum reservoirs, boost controllers, windshield washer hookups or workshop air/water routing, this kit covers the most frequently used sizes. Each hose is made from black silicone with smooth inner and outer walls, about 3 mm wall thickness, and rated for typical vacuum and low-pressure fluid work. The set is designed to be easy to cut, route and secure with clamps or push-fit connectors for fast repairs and custom plumbing on cars, trucks, motorcycles and small equipment.

What sizes are included and how long are the hoses?

The kit contains six silicone vacuum hoses, each approximately 4.92 feet (5 ft) long. Inner diameters included 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), covering most vacuum and low-pressure plumbing needs.

• Six tubes, each ~4.92 ft long for flexible routing and multiple repairs.
• IDs: 1/8", 5/32", 3/16", 1/4", 5/16", 3/8" for broad compatibility.
• Uniform ~3 mm wall thickness for consistent fit and sealing.

How much pressure and temperature can these silicone lines handle?

These hoses are specified for general vacuum and low-pressure fluid work: a working pressure of 43 PSI, room-temperature burst pressure up to 130 PSI, and a tested high-temperature burst around 100 PSI. The silicone material remains flexible across a wide temperature span, making it suitable for under-hood exposures and external routing.

• Working pressure: 43 PSI — suitable for vacuum lines and low-pressure air/water.
• Burst pressures: ~100 PSI at high temperatures; ~130 PSI at room temperature.
• Temperature tolerance from -40°F to 392°F for thermal stability in engines.

Will these tubes resist aging, deformation and leaks in automotive use?

The hoses are molded from quality black silicone designed to resist hardening, cracking and deformation from heat and repeated flexing. The smooth interior and consistent wall thickness provide reliable sealing when paired with clamps, fittings or push-on connectors, though they are not rated for fuel or harsh solvents.

• Silicone construction resists heat, ozone and common aging factors.
• Smooth inner/outer walls simplify sliding over fittings and cleaning.
• Not recommended for oil, gasoline or aggressive chemical transfer.

How easy is installation and what applications are appropriate?

Installation is straightforward: cut to length, select the correct ID for the fitting, and secure with a clamp or hose barb. The kit suits vacuum routing, boost control lines, windshield washer plumbing, small air hoses and workshop water lines on cars, motorcycles, ATVs and small machinery.

• Cut-to-fit lengths for custom routing and repairs.
• Use clamps or push-fit fittings for leak-free connections.
• Intended for air and water — avoid fuel or oil-carrying applications.

Who is this for: mechanics, DIY enthusiasts, custom fabricators and fleet maintainers who need a complete range of common silicone vacuum tube sizes in a single kit. OFBAND’s set is ideal for routine under-hood repairs, prototyping vacuum circuits, replacing brittle OEM lines and building neat, heat-tolerant routing in performance or restoration projects.
