This is a listing for 50cm (half a meter) of soft and flexible Silicone Tubing, each "item" you buy is half a meter - if you want a meter, buy quantity 2, if you want 1.5 meters buy quantity 3, you get the idea....

This tubing has an internal diameter of 3mm, but will easily push fit over hard fittings up to 5mm being soft silicone. The OD is 5mm.

This is not "super stretchy" type surgical tube, just regular old silicone tube.

Heat tolerance appears good, I tested against my soldering iron at 320 Degrees and it didn't make a mark. I don't have any specs on chemical or fuel resistance sorry, I don't have any specs at all apart from dimensional.

A good tube for fitting onto the Mini Air Pumps that I sell which have a 3mm output nozzle, as well of course as a million other uses.

One neat use for this tube is if you have an especially troublesome desoldering job, fit a cm or so over the end of your solder sucker to make a better seal over the iron tip.

Do not even think about using for food or medical type things, seriously now, this is tube from unknown random unknown chinese vendors who probably operate out of an oozing back alleyway in darkest Shenzhen, and could be made from recycled rubber gloves and sticking plasters for all I know.
