IP67 vs IP34
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP34 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 3) and liquid protection (level 7 vs 4). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP34 provides > 2.5 mm — tool / wire and splashing water (all directions).
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.
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.

The exact difference (IP67 vs IP34)
Solid protection
IP67
Level 6 — Dust-Tight
IP34
Level 3 — > 2.5 mm — Tool / Wire
IP67 provides "Dust-Tight" (level 6), while IP34 provides "> 2.5 mm — Tool / Wire" (level 3). IP67 is 3 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP34
Level 4 — Splashing Water (all directions)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP34 handles 50–100 kPa (Splashing Water (all directions)). 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.
