| Applies when | peracetic acid, PAA, peroxyacetic acid |
|---|---|
| Avoid | CPVC, PP, PVC, PVC-GF (Valve) |
| Recommend instead | Hayward Flow Control PVDF or PTFE-wetted valves/strainers (Valve) |
| Rationale | Peracetic Acid at 40% concentration is one of the most restrictive rows in Hayward Flow Control's own chemical resistance table: CPVC, PP, PVC, and PVC-GF all rate 'X' (not recommended) - a materially harder chemistry than most oxidizers captured elsewhere in this project, since PVC/CPVC are otherwise broadly compatible materials across nearly every other chemistry in the same table. Only PTFE and PVDF rate 'A' (excellent). EPDM rates 'B' only (derates to 'C' per Hayward's own wetted-elastomer caveat), Viton rates 'A'. Single-vendor confidence pending a second independent confirmation source. |
