Question 1

I see it is rated for 500 degrees. Do you think I could push it to around 510-525? It would have ambient pressure water flowing through it.

Accepted Answer

No. To put what follows in plain english, it will behave like an elbow macaroni in a pressure cooker - transforming into a distended gelatinous form before turning into complete mush. Here's a less evocative description of what happens. The tubing may withstand 500°F dry for a short time.  300°F steam will break down the siloxane bonds in most types of silicone tubing, only a few special formulas of silicone will provide service that hot.  Water boils at 212°F at atmospheric pressure or 0 psig, at 300°F to be a liquid the pressure has to be over 55 psig, at 500°F to be a liquid the pressure has to be over 675 psig. The available literature suggests that at a fraction of that pressure materials migrate into elastomers and form pockets within them changing the elastomer's properties. The combination of water, termperature, and pressure won't work out well for silicone, and I'm not sure you will find a flexible tubing that will work.

Question 2

Anybody knows what the durometer hardness (Shore A) of this tubing is? Thanks.

Accepted Answer

1/8 x 1/4 that we sell is SHORE-A 50 hardness.

Question 3

can you use it in a bottom load water  cooler

Accepted Answer

As long as your device calls for 1/8" ID tubing and will not exerting too much negative or positive pressure in the tubing, it should be fine. It states it is BPA and lead free; food safe, medical safe.

Question 4

can this be used for an RO water filtration system and a low ph?

Accepted Answer

Yes, you can certainly use it in all water filtration applications. Silicone will not react to low pH (acidic water), with the exception of the presence of hydrofluoric acid, which of course will not be present in your water.
