Food Grade Silicone Vacuum Hose Tube — Flexible Rubber Pipe, Multiple Colors & Sizes

Match the inner diameter (ID) to the barb or fitting you're connecting to. For example, a 4mm ID hose fits a 4mm barb fitting. If you need a snug, leak-resistant seal, choose an ID that is 0.5–1mm smaller than the barb OD. Sizes are listed as ID × OD — for instance, 4×6mm means 4mm inner diameter and 6mm outer diameter (approximately 5/32" × 15/64"). When in doubt, measure your existing hose or fitting with calipers before ordering.

Food-grade silicone tubing generally withstands temperatures from approximately -60°C (-76°F) to +200°C (+392°F). This makes it suitable for most automotive vacuum lines, turbo boost applications, home brewing, and food processing lines. For continuous high-heat exposure above 180°C, verify your specific application requirements.

Yes. This tubing is made from food-grade silicone, which is typically non-toxic, odor-free, and tasteless. It is commonly used in home brewing, winemaking, and food processing transfer lines. Always verify compliance with your local food safety regulations for commercial applications.

Silicone generally offers good UV and ozone resistance compared to standard EPDM or nitrile rubber. For long-term outdoor exposure, the transparent variant may show slight yellowing over time; colored variants typically perform better in UV-exposed settings. In most cases, silicone outperforms standard rubber in outdoor durability.

This hose is compatible with standard barb fittings that match the inner diameter. It works with push-on barb connectors, T-fittings, and elbow fittings in the corresponding ID size. No special thread standard is required — simply push the hose over the barb and secure with a hose clamp if needed for pressurized applications.

Transparent hoses let you visually monitor fluid flow, which is useful in brewing, aquarium, or diagnostic applications. Colored hoses are ideal for color-coding multiple lines in automotive or lab setups to avoid mix-ups at a glance. Both variants share the same food-grade silicone material and performance characteristics.

Yes. Each listing is sold per 1-meter length. You can cut it to any shorter length using scissors or a utility knife. The cut ends remain clean and do not fray, maintaining a reliable seal on barb fittings without additional finishing.

Silicone generally outperforms standard rubber and PVC in temperature range, flexibility at low temperatures, and resistance to ozone and UV degradation. PVC can become brittle in cold conditions and may off-gas plasticizers over time. Standard rubber degrades faster under heat and UV. For vacuum line replacement and food-contact applications, silicone is typically the preferred choice.
