IP44 vs IP68
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP44 and IP68 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 4 vs 8). IP44 is rated for > 1 mm — small wires and splashing water (all directions), while IP68 provides dust-tight and continuous immersion (manufacturer-specified).
IP44 protects against small solid objects (1 mm) and splashing water from any direction. It is the common minimum rating for outdoor-covered fixtures and bathroom zone equipment.
IP68 is dust-tight and protects against continuous immersion in water under conditions specified by the manufacturer (typically deeper than 1 meter for prolonged periods). The standard for submersible and marine equipment.

The exact difference (IP44 vs IP68)
Solid protection
IP44
Level 4 — > 1 mm — Small Wires
IP68
Level 6 — Dust-Tight
IP44 provides "> 1 mm — Small Wires" (level 4), while IP68 provides "Dust-Tight" (level 6). IP68 is 2 levels higher.
Liquid protection
IP44
Level 4 — Splashing Water (all directions)
IP68
Level 8 — Continuous Immersion (manufacturer-specified)
IP44 handles 50–100 kPa (Splashing Water (all directions)), while IP68 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP68 provides 4 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP68 offers higher overall protection than IP44. Choose IP68 for harsher environments; IP44 may suffice for milder conditions and can be more cost-effective.
