Install / Failure Note

Not all PFA grades resist fluorosurfactants equally — the vendor's own language flags that lower PFA grades are vulnerable, a real material-grade distinction that gets lost when a spec just says "PFA tubing" without naming the grade.

Ozone disinfection isn't chlorine, and a tubing spec built around chlorine resistance doesn't automatically cover it — Altaflo 550's explicit ozone rating is a genuinely separate compatibility claim from the sodium-hypochlorite data that drives most disinfection tubing specs.

Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
