Max operating pressure for BE Online SPE (PLRP-S)?

Does anyone happen to know the maximum or optimal operating pressure of a Bond Elut Online SPE cartridge, 2.1 x 12.5 mm, 15 um PLRP-S, Part Number 5982-1271?

On the Agilent site it says "Maximum gradient pressure is 250 psi [17 bar]" but that seems really low given that 15 um PLRP-S media can run safely at over 1500 psi/103 bar.
