Decoding IP Ratings
IP ratings use two digits: first for solid particle protection (0-6), second for liquid ingress (0-8).
IP67
6 = dust-tight. 7 = protected against temporary immersion (30 min at 1m). Ideal for outdoor electronics and washdown environments.
IP68
8 = continuous immersion beyond 1 meter. Used in submersible pumps and marine electronics.
Which Do You Need?
- IP67 — sufficient for 95% of outdoor and industrial applications
- IP68 — required only for continuous submersion
