I did a bit of googling, and found
this.
While I haven't read it deeply enough to get a full understanding, the Statement of Problem section describes occasional polycarbonate failure in a shattering mode. On the other hand, it describes shattering pressures of around 1000psi. The scale drawing actually doesn't give scale; I don't know if 25.0 (outside diameter) is 25.0 mm, 25.0 cm, 25.0 in, or something even larger or smaller.
My takeaway here is that if the polycarbonate is thick enough that failure is not a possibility (and I do not know where that number is), it should work well. Otherwise, unless the specific composition and manufacture of your tubing is known to fail only through tearing or bubbling at the operational parameters, don't consider it safe.
