IP25 vs IP38
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP38 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 3) and liquid protection (level 5 vs 8). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP38 provides > 2.5 mm — tool / wire and continuous immersion (manufacturer-specified).
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 5.
IP38 provides protection against solid objects larger than 2.5 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 8.

The exact difference (IP25 vs IP38)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP38
Level 3 — > 2.5 mm — Tool / Wire
IP25 provides "> 12.5 mm — Finger" (level 2), while IP38 provides "> 2.5 mm — Tool / Wire" (level 3). IP38 is 1 level higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP38
Level 8 — Continuous Immersion (manufacturer-specified)
IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP38 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP38 provides 3 levels more liquid protection.

Recommendation
IP38 offers higher overall protection than IP25. Choose IP38 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
