IP08 vs IP49K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP08 and IP49K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 8 vs 9K). IP08 is rated for no protection and continuous immersion (manufacturer-specified), while IP49K provides > 1 mm — small wires and high-pressure, high-temp water jets.
Built to withstand no protection against solid objects and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. Classified as IEC 60529 ingress protection code IP08, it pairs solid level 0 with liquid level 8.
Built to withstand protection against solid objects larger than 1.0 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. Classified as IEC 60529 ingress protection code IP49K, it pairs solid level 4 with liquid level 9K.

The exact difference (IP08 vs IP49K)
Solid protection
IP08
Level 0 — No Protection
IP49K
Level 4 — > 1 mm — Small Wires
IP08 provides "No Protection" (level 0), while IP49K provides "> 1 mm — Small Wires" (level 4). IP49K is 4 levels higher.
Liquid protection
IP08
Level 8 — Continuous Immersion (manufacturer-specified)
IP49K
Level 9 — High-Pressure, High-Temp Water Jets
IP08 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP49K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP49K provides 1 level more liquid protection.

Recommendation
IP49K offers higher overall protection than IP08. Choose IP49K for harsher environments; IP08 may suffice for milder conditions and can be more cost-effective.
