Feelers 1/4" ID x 3/8" OD Silicone Tubing Food Grade Pure Silicon Pipe Hose Tube High Temp Home Brewing Winemaking, 3.28ft Length

what is the durometer of this tubing?

Re: 3/16x3/8 tube, is the od accurate? i already have 3/16 (5mm)x5/16 (8mm) tubing & need a thicker wall. also, is this pure silicone w/ no fillers?

Is this tubing still considered food safe when food/water can come in contact with cut edges of the tubing (ie no fiberglass)?

What is the minimum bend radius without kinking?
