HPS HTSVH35-BLKx5 Black 5′ High Temp Silicone Vacuum Tubing
The HPS tube is manufactured from high-temperature silicone designed for heavy-duty connections and is compatible with marine and industrial applications. It features a 3.5mm ID and a 5-foot length on a single roll. The product emphasizes reliability under tough operating conditions and is suitable for turbos, intercooler piping, and radiator cooling systems where higher heat resistance is required. Applications include DIY projects and professional installations where stable performance under hot environments matters.
Tvent 1/8″ Fuel Line Hose – 6 Feet
The Tvent hose has an ID of 3.5mm (1/8″) and measures 6 feet in length, with a wide compatibility range covering Honda overflow lines, lawn equipment, motorcycles, ATVs, generators, and more. Constructed from NBR rubber, it resists diesel, gasoline, oil, hydraulic fluids, and coolant. It’s suitable for engines and mechanical environments that require a robust, flexible fuel and vent line with a temperature range from -40°C to 100°C.
Gephynm Vacuum Hose Automotive, 10 ft
Gephynm offers a high-temperature silicone vacuum hose with a 10-foot length and 1/8 inch ID (roughly 3 mm). The hose uses reinforced silicone with low odor and strong heat resistance, reducing the risk of collapse or deformation under pressure. It is designed for air and water transmission in engines, and while not suitable for fuel or oil lines, it is well-suited for automotive air systems, experiments, and irrigation setups that demand stability in challenging temperatures.
Ucreative 10FT ID 1/8″ Silicone Vacuum Tubing
Ucreative provides a 10-foot silicone vacuum tubing with a 1/8 inch ID (3mm) and a wall thickness matching typical high-temperature hoses. It lists a working pressure around 43 PSI and a burst pressure up to 130 PSI at room temperature. Temperature tolerance spans from -40°F to 428°F, making it a versatile choice for automotive air lines, laboratory equipment, and DIY projects that involve heated environments.
EVIL ENERGY 5/32 Silicone Vacuum Tubing 10FT
EVIL ENERGY offers a 10-foot silicone vacuum line with a 4mm (5/32″) ID, targeting larger diameter needs while retaining silicone’s high-temperature performance. The wall thickness is designed to resist collapse under vacuum, and the tube is FDA-compliant silicone. Suitable for engine vacuum runs, irrigation lines, and experimental setups where a slightly larger bore is advantageous and compatibility with various fuels and lubricants is necessary.
Buying Guide
- Inner diameter vs. outer diameter: Confirm that the hose ID matches your fitting size to prevent leaks or loose connections. If uncertain, choose a slightly larger ID with compatible adapters.
- Material and temperature rating: Silicone hoses provide excellent temperature resistance and flexibility, but consider alternatives like NBR for specific chemical resistances. Note temperature ranges from approximate sub-zero to well above 400°F for some models.
- Pressure and burst limits: For automotive and turbocharged systems, higher burst pressures reduce risk under peak pressure. Match the hose’s working and burst pressures to your system’s expected loads.
- Chemical compatibility: Fuel lines, oils, water, and coolant have different chemical profiles. Use dedicated lines for fuels and oils and reserve silicone or rubber hoses for air and water transmission where appropriate.
- Length and routing: Select lengths that minimize unnecessary coiling or bending. A longer hose can be routed more easily around components but may introduce extra slack or weight.
- Certification and safety: FDA-grade silicone and food-grade materials add safety margins when used in non-standard environments or food-related equipment. Ensure compatibility with your organization’s safety standards.
- Installation considerations: Use appropriate clamps and fittings rated for the hose ID and operating temperature. Avoid sharp bends that can cause collapse or kinking, particularly in smaller diameters.
- Maintenance and replacement: Inspect hoses for cracks, hardening, or deformation. Replace hoses showing signs of wear to prevent leaks and failures in critical systems.
