What to know before buying

Listing details to confirm

Temperature claims differ between the features section, which states -40℃ to +220℃, and the product description, which states -40°C to 200°C. The dimensions entry “1W millimetres” is also inconsistent with the separately stated 7 mm outside diameter and 1 mm wall thickness. The features call the tube clear while the title and colour detail say black. Confirm the selected listing's colour, measurements and applicable temperature limit before use.

Who is it for?

A good fit for

Buyers needing a 5 mm inner-diameter silicone tube for a small pump or air line.
Liquid- or water-transfer setups where the listed 7 mm outside diameter and 3 m length fit the route and connections.
Users looking for flexible tubing that the listing says can be reused.

Less suited to

Installations requiring a confirmed temperature limit above 200°C, unless the manufacturer clarifies the conflicting claims.
Setups needing an inner or outer diameter different from the listed measurements.

Aggregate ratings lean positive, with most ratings in the five-star category, alongside some three- and one-star ratings. With no customer-comment summary available, these figures do not establish what buyers liked or why some rated it less favourably. Treat them as a broad signal only, and prioritise the stated dimensions and conflicting temperature and colour details for compatibility decisions.

Frequently asked questions

What size is this silicone tubing?

The listing states a 5 mm inner diameter, 7 mm outer diameter and 1 mm wall thickness. Check these against your fittings before ordering.

How long is the tube?

The listed length is 3 metres.

What temperature can it handle?

The listing gives two different limits: -40℃ to +220℃ in the features and -40°C to 200°C in the product description. Confirm the applicable limit before using it near temperature extremes.

Is the tube black or clear?

The title and colour detail say black, but a feature description calls the tube clear. The listed colour is therefore inconsistent and should be confirmed.
