IP64 vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP64 and IP67 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 4 vs 7). IP64 is rated for dust-tight and splashing water (all directions), while IP67 provides dust-tight and temporary immersion (up to 1 m).
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).
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 (IP64 vs IP67)
Solid protection
IP64
Level 6 — Dust-Tight
IP67
Level 6 — Dust-Tight
Both IP64 and IP67 share the same solid protection: Dust-Tight.
Liquid protection
IP64
Level 4 — Splashing Water (all directions)
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP64 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 IP64. Choose IP67 for harsher environments; IP64 may suffice for milder conditions and can be more cost-effective.
