IP67 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 2) and liquid protection (level 7 vs 5). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
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.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 5.

The exact difference (IP67 vs IP25)
Solid protection
IP67
Level 6 — Dust-Tight
IP25
Level 2 — > 12.5 mm — Finger
IP67 provides "Dust-Tight" (level 6), while IP25 provides "> 12.5 mm — Finger" (level 2). IP67 is 4 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP67 provides 2 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP25. Choose IP67 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
