Is 3/16 inside or outside diameter?

Incorrect the product i received was actually 3/16 outside diameter. I used this question and the answer provided and now have the wrong product. It is actually 3/16 outside and 1/8 inside diameter.

I need to know 'exactly' what this tubing made of: pvc? polyurethane? nylon? silicone? vinyl?

I believe it is silicone ... Very soft and flexible ... but mine had several kinks in it that would not come out because of the way it was rolled and crammed in the box ...

Is this product made of silicone or plastic?

Definitely silicone! It’s good stuff! Can be a bit difficult to work with since it’s so soft and rubbery, but all you have to do is wet the nozzle before attaching the hose and it will slip on a whole lot easier! This is a great deal! I’ve ordered it twice now and never once did I receive it with a kink or bend!

Is this tubing food grade?

It is aquarium safe so I would be willing to assume it is food grade.
