IP29K vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 0) and liquid protection (level 9K vs 8). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IPX8 provides no protection and continuous immersion (manufacturer-specified).
With IP29K, an enclosure receives protection against solid objects larger than 12.5 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 9K.
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 (IP29K vs IPX8)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IPX8
Level 0 — No Protection
IP29K provides "> 12.5 mm — Finger" (level 2), while IPX8 provides "No Protection" (level 0). IP29K is 2 levels higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP29K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP29K provides 1 level more liquid protection.

Recommendation
IP29K offers higher overall protection than IPX8. Choose IP29K for harsher environments; IPX8 may suffice for milder conditions and can be more cost-effective.
