IP34 vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP34 and IP67 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 6) and liquid protection (level 4 vs 7). IP34 is rated for > 2.5 mm — tool / wire and splashing water (all directions), while IP67 provides dust-tight and temporary immersion (up to 1 m).
IP34 is an ingress protection code that ensures protection against solid objects larger than 2.5 mm and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 4.
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 (IP34 vs IP67)
Solid protection
IP34
Level 3 — > 2.5 mm — Tool / Wire
IP67
Level 6 — Dust-Tight
IP34 provides "> 2.5 mm — Tool / Wire" (level 3), while IP67 provides "Dust-Tight" (level 6). IP67 is 3 levels higher.
Liquid protection
IP34
Level 4 — Splashing Water (all directions)
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP34 handles 50–100 kPa (Splashing Water (all directions)), while IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP67 provides 3 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP34. Choose IP67 for harsher environments; IP34 may suffice for milder conditions and can be more cost-effective.
