IP42 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP42 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 0) and liquid protection (level 2 vs 8). IP42 is rated for > 1 mm — small wires and dripping water at 15° tilt, while IPX8 provides no protection and continuous immersion (manufacturer-specified).
With IP42, an enclosure receives protection against solid objects larger than 1.0 mm and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 2.
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 (IP42 vs IPX8)
Solid protection
IP42
Level 4 — > 1 mm — Small Wires
IPX8
Level 0 — No Protection
IP42 provides "> 1 mm — Small Wires" (level 4), while IPX8 provides "No Protection" (level 0). IP42 is 4 levels higher.
Liquid protection
IP42
Level 2 — Dripping Water at 15° Tilt
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP42 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IPX8 provides 6 levels more liquid protection.

Recommendation
IPX8 offers higher overall protection than IP42. Choose IPX8 for harsher environments; IP42 may suffice for milder conditions and can be more cost-effective.
