IP67 vs IP43
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP43 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 4) and liquid protection (level 7 vs 3). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP43 provides > 1 mm — small wires and spraying water (up to 60°).
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.
IP43 protects against 1 mm solid objects and spraying water up to 60° from vertical. A practical rating for sheltered equipment subject to light angled spray, such as covered outdoor fixtures.

The exact difference (IP67 vs IP43)
Solid protection
IP67
Level 6 — Dust-Tight
IP43
Level 4 — > 1 mm — Small Wires
IP67 provides "Dust-Tight" (level 6), while IP43 provides "> 1 mm — Small Wires" (level 4). IP67 is 2 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP43
Level 3 — Spraying Water (up to 60°)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP67 provides 4 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP43. Choose IP67 for harsher environments; IP43 may suffice for milder conditions and can be more cost-effective.
