Color Silicone Tube Food Grade Flexible Tubing Hose Rubber Pipe I.D 2 4 5 6 8mm

Match the tube's inner diameter (ID) to the outer diameter (OD) of your barbed fitting or pump port. For example, a 4 mm barbed fitting pairs with the 4×6 mm or 4×7 mm tube. A snug fit over the barb creates a leak-resistant seal without a clamp; add a hose clamp for pressurized lines above 0.5 bar.

Yes. The tubing is made from platinum-cured silicone, which is free of BPA, phthalates, and plasticizers. It is odorless and tasteless, making it suitable for homebrewing, kombucha, juice transfer, and similar food and beverage applications.

The tubing is rated to approximately +200 °C (+392 °F), which covers boiling water (100 °C) and typical wort temperatures. It can also withstand brief autoclave cycles used in laboratory sterilization. Avoid sustained exposure above the rated temperature, as this can accelerate surface degradation over time.

The pigments used in colored variants are compounded into the silicone matrix rather than applied as a surface coating, so they do not leach or bleed under normal operating conditions. Transparent and Transparent Red variants contain no added pigment and are a good choice when visual flow monitoring is needed.

Silicone outperforms vinyl in three key areas: temperature range (vinyl softens above ~60 °C), odor neutrality (vinyl can impart a plastic taste), and long-term flexibility (vinyl stiffens and cracks with age). Latex is flexible but not food-safe and degrades with ozone and UV exposure. Silicone is the preferred choice for any application where fluid purity or temperature resistance matters.

Yes. Silicone is the standard material for peristaltic pump tubing because it recovers its round cross-section after each roller compression without cracking or permanently deforming. Select the ID that matches your pump head's specified tube size — common lab peristaltic pumps use 2 mm, 4 mm, or 5 mm ID tubing.

Measure the longest single run you need, then add 15–20% for routing around obstacles and future repositioning. The 2 m cut suits most single-tank air line or return line runs. The 5 m cut works well for multi-tank racks or sump setups with longer return paths. The 10 m cut is cost-effective if you are outfitting multiple tanks or want a spare supply on hand.
