IP25 vs IP26
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP26 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 5 vs 6). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP26 provides > 12.5 mm — finger and powerful water jets (12.5 mm nozzle).
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.
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 (IP25 vs IP26)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP26
Level 2 — > 12.5 mm — Finger
Both IP25 and IP26 share the same solid protection: > 12.5 mm — Finger.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP26 provides 1 level more liquid protection.

Recommendation
IP26 offers higher overall protection than IP25. Choose IP26 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
