IP43 vs IP26
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP43 and IP26 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 2) and liquid protection (level 3 vs 6). IP43 is rated for > 1 mm — small wires and spraying water (up to 60°), while IP26 provides > 12.5 mm — finger and powerful water jets (12.5 mm nozzle).
IP43 protects against 1 mm solid objects and spraying water up to 60° from vertical. A practical rating for sheltered equipment subject to light angled spray, such as covered outdoor fixtures.
Built to withstand protection against solid objects larger than 12.5 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP26, it pairs solid level 2 with liquid level 6.

The exact difference (IP43 vs IP26)
Solid protection
IP43
Level 4 — > 1 mm — Small Wires
IP26
Level 2 — > 12.5 mm — Finger
IP43 provides "> 1 mm — Small Wires" (level 4), while IP26 provides "> 12.5 mm — Finger" (level 2). IP43 is 2 levels higher.
Liquid protection
IP43
Level 3 — Spraying Water (up to 60°)
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP26 provides 3 levels more liquid protection.

Recommendation
IP26 offers higher overall protection than IP43. Choose IP26 for harsher environments; IP43 may suffice for milder conditions and can be more cost-effective.
