IP69K vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP69K and IP64 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 9K vs 4). IP69K is rated for dust-tight and high-pressure, high-temp water jets, while IP64 provides dust-tight and splashing water (all directions).
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.
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).

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