IP67 vs IP68
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP68 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 7 vs 8). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP68 provides dust-tight and continuous immersion (manufacturer-specified).
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.
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 (IP67 vs IP68)
Solid protection
IP67
Level 6 — Dust-Tight
IP68
Level 6 — Dust-Tight
Both IP67 and IP68 share the same solid protection: Dust-Tight.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP68
Level 8 — Continuous Immersion (manufacturer-specified)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP68 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP68 provides 1 level more liquid protection.

Recommendation
IP68 offers higher overall protection than IP67. Choose IP68 for harsher environments; IP67 may suffice for milder conditions and can be more cost-effective.
