IP67 vs IP09K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP09K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 0) and liquid protection (level 7 vs 9K). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP09K provides no protection and high-pressure, high-temp water jets.
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 IP09K rating offers no protection against solid objects and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 9K.

The exact difference (IP67 vs IP09K)
Solid protection
IP67
Level 6 — Dust-Tight
IP09K
Level 0 — No Protection
IP67 provides "Dust-Tight" (level 6), while IP09K provides "No Protection" (level 0). IP67 is 6 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP09K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP09K provides 2 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP09K. Choose IP67 for harsher environments; IP09K may suffice for milder conditions and can be more cost-effective.
