IP64 vs IP69K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP64 and IP69K are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 4 vs 9K). IP64 is rated for dust-tight and splashing water (all directions), while IP69K provides dust-tight and high-pressure, high-temp water jets.
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).
IP69K is dust-tight and resists high-pressure (8–10 MPa), high-temperature (80 °C) water jets. The highest IP rating, required for food, beverage, and pharmaceutical washdown environments.

The exact difference (IP64 vs IP69K)
Solid protection
IP64
Level 6 — Dust-Tight
IP69K
Level 6 — Dust-Tight
Both IP64 and IP69K share the same solid protection: Dust-Tight.
Liquid protection
IP64
Level 4 — Splashing Water (all directions)
IP69K
Level 9 — High-Pressure, High-Temp Water Jets
IP64 handles 50–100 kPa (Splashing Water (all directions)), while IP69K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP69K provides 5 levels more liquid protection.

Recommendation
IP69K offers higher overall protection than IP64. Choose IP69K for harsher environments; IP64 may suffice for milder conditions and can be more cost-effective.
