IP43 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP43 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 0) and liquid protection (level 3 vs 8). IP43 is rated for > 1 mm — small wires and spraying water (up to 60°), while IPX8 provides no protection and continuous immersion (manufacturer-specified).
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.
IPX8 protects against continuous immersion under manufacturer-specified conditions (depth and duration), with solid protection not specified. The standard for submersible consumer electronics.

The exact difference (IP43 vs IPX8)
Solid protection
IP43
Level 4 — > 1 mm — Small Wires
IPX8
Level 0 — No Protection
IP43 provides "> 1 mm — Small Wires" (level 4), while IPX8 provides "No Protection" (level 0). IP43 is 4 levels higher.
Liquid protection
IP43
Level 3 — Spraying Water (up to 60°)
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IPX8 provides 5 levels more liquid protection.

Recommendation
IPX8 offers higher overall protection than IP43. Choose IPX8 for harsher environments; IP43 may suffice for milder conditions and can be more cost-effective.
