IP67 vs IPX4
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IPX4 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 0) and liquid protection (level 7 vs 4). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IPX4 provides no protection 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.
IPX4 (solid protection not specified) resists splashing water from any direction. A common minimum for bathroom and outdoor-covered appliances where dust sealing is not required.

The exact difference (IP67 vs IPX4)
Solid protection
IP67
Level 6 — Dust-Tight
IPX4
Level 0 — No Protection
IP67 provides "Dust-Tight" (level 6), while IPX4 provides "No Protection" (level 0). IP67 is 6 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IPX4
Level 4 — Splashing Water (all directions)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IPX4 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 IPX4. Choose IP67 for harsher environments; IPX4 may suffice for milder conditions and can be more cost-effective.
