Food Grade Silicone Tube Color Hose Beer Vacuum Pipe Soft Rubber ID 1mm 2mm-8mm

Match the inner diameter (ID) to the outer diameter of your barbed fitting or nozzle — the tube should stretch slightly over the barb for a secure, leak-free seal. The outer diameter (OD) matters when the tube must pass through a grommet, bulkhead, or panel hole. If you are connecting to a standard 1/4-inch barb, an ID of approximately 6 mm is a close metric match.

Yes. The tubing is made from food grade silicone rubber, which is odorless, tasteless, and non-toxic. It will not leach plasticizers or impart off-flavors to beer, wine, juice, or water. It can also be sanitized with standard brewing sanitizers (Star San, iodophor) or boiled repeatedly without degrading.

The tubing is rated from -60°C to 180°C (-76°F to 356°F). This covers most sterilization scenarios including boiling water (100°C) and short-duration steam exposure. For continuous high-pressure steam above 150°C, consult a specialist, as wall thickness and pressure rating interact at elevated temperatures.

The pigments used in the colored variants are incorporated into the silicone compound rather than applied as a surface coating, so they do not flake or bleed under normal use. However, if color integrity for food contact is a concern, the Transparent variant eliminates any pigment variable entirely.

Yes. Silicone is widely used in aquarium applications because it is inert, flexible, and does not off-gas into the water. For CO2 diffusion lines, note that silicone is slightly more gas-permeable than rigid tubing, which is generally acceptable for low-pressure planted tank setups. For high-pressure CO2 regulators, verify the working pressure against the wall thickness of your chosen size.

Use a sharp pair of scissors or a fresh utility knife blade and cut in a single motion rather than sawing back and forth. For very small diameters (1–2 mm ID), inserting a stiff wire or toothpick into the bore before cutting helps maintain the round cross-section. A straight, square cut also ensures a better seal against barbed fittings.

One meter covers most single-run connections — typical homebrew transfer lines, aquarium air manifold drops, and bench lab connections are well within 1 meter. For longer runs or multi-line setups, simply add the quantity you need to your cart; each unit is a separate 1-meter length that can be joined with a barbed coupler if needed.
