Tubing material

Tubing material

Tubing material

Hi All,

I'm looking for a nylon tube which is food grade approved and it should withstand upto 25bar water pressure.

I want to use the pipe for drinking water applications. Maximum operating pressure is 25bar.

Tube OD: 8mm
ID : 5 - 6mm
Pls suggest any suite tube material wit its make.

Thanks in advance.

RE: Tubing material

I don't think you're going to find nylon tubing for this application. It's too absorbent for food application.

What are your flexibility and temperature requirements?

RE: Tubing material

In lieu of any temp requirements, I'd look at PFA tubing.

RE: Tubing material

I have found food grade polyethylene tube in Parker make. But it's pressure handling capacity is very low.
I'm looking for atleast 16 bar

RE: Tubing material


these guys sell HDPE 16 bar pipe.

RE: Tubing material

What's wrong with copper pipe?

RE: Tubing material

Or Stainless steel? There are high pressure hoses (plastic liners with metal or kevlar braid) but you getting rather expensive.

P.E. Metallurgy, consulting work welcomed

RE: Tubing material

download Parker's tubing catalog (Link below) and search for something like FDA


RE: Tubing material

Hello TugboatEng,

Flexibility: the more will more better.
Temperature: 25 to 40 degree celcius.

Hello LittleInch,
Yes. we can go with copper. But we prefer plastic/rubber tube because of less price than Copper tubes.

RE: Tubing material

The problem, as you're discovering, is that the cheaper pipes have limited maximum pressure.

If you want higher pressure then it gets more expensive than stainless steel or copper.

You can buy UHMW PE pipe which will do 25 bar I think.

RE: Tubing material

Hello Littleinch,
Yeah. Food grade tubes with higher pressure capacity are very expensive than stainless steel or copper.

I'll check for copper tube price, if that fits our pocket.

Thanks for all your support and knowledge sharing.
