Measure the outer diameter of your barbed fitting or nipple — this should match the inner diameter of the hose for a snug, leak-free seal. For example, a 6mm barb fits best with a 6mm ID hose. If you're between sizes, size down slightly; silicone stretches to grip the barb without needing a clamp in many low-pressure applications.

Yes. The hose is made from food-grade silicone that is odorless, tasteless, and non-toxic. It does not leach plasticizers or impart flavor to liquids, making it suitable for wort transfer, fermentation airlocks, siphoning, and other brewing applications where the hose contacts your beverage directly.

This silicone tube is rated for approximately -60°C to +200°C (-76°F to +392°F). It remains flexible at freezer temperatures and can handle hot wort, steam, and automotive coolant without softening or cracking. Avoid sustained exposure above 200°C, which may cause surface degradation over time.

Silicone rubber has inherently good UV and ozone resistance compared to standard PVC or rubber hoses. For occasional outdoor use — such as garden irrigation or outdoor brewing setups — it performs well. For permanent outdoor installations in direct sunlight, consider adding a UV-protective sleeve or routing the hose through conduit for extended service life.

Yes, this hose is commonly used for vacuum lines, aquarium air tubing, and low-pressure pneumatic applications. The soft silicone wall collapses slightly under strong vacuum in very small diameters — if you need to maintain bore shape under high vacuum, choose a larger wall thickness (larger OD relative to ID) or use a spiral-reinforced hose for that application.

Use a sharp utility knife or scissors on a flat surface. Silicone cuts cleanly without fraying. For a perfectly square cut — important when seating against a flat-face fitting — use a miter box or a straight-edge guide. Avoid sawing motions, which can leave a ragged edge that reduces seal quality.

All three lengths are the same hose material and diameter — only the cut length differs. The 1 Metre option suits short connections, repairs, or sampling a new size before committing to a longer run. The 5 Metre and 10 Metre options are more economical per metre and suited to longer routing runs in brewing systems, aquariums, or workshop plumbing.
