IP26 vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP26 and IP67 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6) and liquid protection (level 6 vs 7). IP26 is rated for > 12.5 mm — finger and powerful water jets (12.5 mm nozzle), while IP67 provides dust-tight and temporary immersion (up to 1 m).
Built to withstand protection against solid objects larger than 12.5 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP26, it pairs solid level 2 with liquid level 6.
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.

The exact difference (IP26 vs IP67)
Solid protection
IP26
Level 2 — > 12.5 mm — Finger
IP67
Level 6 — Dust-Tight
IP26 provides "> 12.5 mm — Finger" (level 2), while IP67 provides "Dust-Tight" (level 6). IP67 is 4 levels higher.
Liquid protection
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP67 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP26. Choose IP67 for harsher environments; IP26 may suffice for milder conditions and can be more cost-effective.
