IP68 vs IP41
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP68 and IP41 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 4) and liquid protection (level 8 vs 1). IP68 is rated for dust-tight and continuous immersion (manufacturer-specified), while IP41 provides > 1 mm — small wires and vertically dripping water.
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.
Under IEC 60529, IP41 specifies protection against solid objects larger than 1.0 mm and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 1.

The exact difference (IP68 vs IP41)
Solid protection
IP68
Level 6 — Dust-Tight
IP41
Level 4 — > 1 mm — Small Wires
IP68 provides "Dust-Tight" (level 6), while IP41 provides "> 1 mm — Small Wires" (level 4). IP68 is 2 levels higher.
Liquid protection
IP68
Level 8 — Continuous Immersion (manufacturer-specified)
IP41
Level 1 — Vertically Dripping Water
IP68 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP41 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP68 provides 7 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP68 offers higher overall protection than IP41. Choose IP68 for harsher environments; IP41 may suffice for milder conditions and can be more cost-effective.
