Ray;
There are pages of Tygon tubings. I used the one recommended by the company that said up to 80 PSI at up to 120F was acceptable. They also said that the tubing was optimum for their pump.
It didn't work. I'm looking at other options.

That is unfortunate.
Might you have had better luck asking the manufacturer of TYGON directly?
You do have to watch your back however.
When I purchased mine, I asked for Tygon specfically, but was sent an immitation... I paid THAT company a visit and got things straightened out.
In the end, I examined a few formulas and came to the conclusion that POSSIBLY, a cheeper immitation MIGHT work, but I was not willing to do the proofing needed to Ok it.
I'm a Tygon Man.
Anyway, it is a shame that the pump mfg. gave you poor advice!
Perhaps they only check the flow rate... and take most other specs from a table.

Yes - at least when you have genuine Tygon brand tubing, you have the grace of Saint Gobain with you...

Would that be this one?

That is the 16 head. You can stack 3 heads of this general type with 3 different flow rates at the same time or three identical flow rates.

Did you notice that the specs on that pump head say it has a max pressure of 25 PSI continuous?

And the specs of that page said 40 - 80 PSI depending on flow rate and tubing.
I measured it at 60 PSI with a pressure guage and at 40 ml / min with a pump setting of 1.0. I repeated this over a period of 3 days. As I increased flow rate to 2, pressure went down as the rollers slipped.
Of course, during my shopping, the VWR pages changed 2x during that week and prices went way up also. The site was unavailable for a day or so, probably while they made all of these changes. However, I did get the pump from another source.
