IP68 Ratings Explained: What Does 'Submersible' Actually Mean?

One of the most critical specifications for submersible actuators and underwater valves is the IP (Ingress Protection) rating. Understanding what IP68 actually means—and what it doesn't mean—is essential for both suppliers and buyers to avoid mismatched expectations and product failures.

IP Rating Structure: The IP code consists of two digits. The first digit (0-6) indicates protection against solid objects (dust, debris), while the second digit (0-9K) indicates protection against liquids (water). IP68 specifically means:

First digit '6': Completely dust-tight; no ingress of dust permitted
Second digit '8': Protected against continuous immersion in water under conditions specified by the manufacturer (typically deeper and longer than IP67)

Crucial Distinction: Unlike IP67 (which specifies immersion up to 1 meter for 30 minutes), IP68 has no standardized time or depth limit in the IEC 60529 standard itself. Instead, manufacturers specify the exact conditions their IP68-rated products can withstand. Common specifications include 5 meters depth for 48+ hours, 8 meters for 96 hours, or even 60 meters (197 feet) for specialized subsea applications ^[3]^[5]^[8]^[9].

IP Rating Comparison for Valve Actuators

IP Rating	Dust Protection	Water Protection	Typical Use Case	Submersible?	Cost Implication
IP54	Limited dust ingress OK	Splash from any direction	Indoor industrial, protected environments	No	Lowest
IP65	Dust-tight	Low-pressure water jets	Outdoor, washdown environments	No	Low-Medium
IP66	Dust-tight	High-pressure water jets	Marine deck, heavy washdown	No	Medium
IP67	Dust-tight	Immersion 1m for 30 min	Temporary submersion, flood-prone areas	Limited	Medium-High
IP68	Dust-tight	Continuous immersion (manufacturer-specified depth/time)	Underwater installations, subsea applications	Yes	High
IP69K	Dust-tight	High-pressure, high-temperature washdown	Food processing, sterilization	No	Highest

IP68 is the highest standard protection for continuous submersion applications. Actual depth and duration specifications vary by manufacturer—always verify specific ratings ^[3]^[5]^[8].

AUMA's IP68 Specification (a leading actuator manufacturer) provides a concrete example: their standard IP68 rating allows continuous immersion up to 8 meters head of water for a maximum of 96 hours, with up to 10 operations permissible during submersion. For more demanding applications, they offer specialized SA-UW versions qualified for 15 meters and SAEx-UW explosion-proof versions for 8 meters ^[8]^[9].

"IP68 is not just splash-proof—it's engineered for real-world underwater conditions with continuous immersion protection. The key difference from IP67 is that IP68 has no time limit, though manufacturers specify their own depth and duration parameters." ^[3]

For Southeast Asian Exporters: When listing submersible actuators on Alibaba.com, be precise about your IP68 specifications. Don't just claim "IP68"—specify the exact depth and duration your product supports (e.g., "IP68 rated for 5 meters depth, 72 hours continuous immersion"). This transparency builds buyer trust and reduces post-sale disputes. Alibaba.com's product attribute system allows detailed specification entry, enabling buyers to filter and compare products based on exact IP rating requirements.

Technical Benchmark: Pumps & Systems reports tested underwater electric actuators capable of operating at depths up to 197 feet (60 meters) for more than 96 hours, representing the high end of subsea actuator capabilities ^[9].

Sealing Technology & Pressure Resistance: The Engineering Behind IP68

Achieving genuine IP68 protection requires sophisticated engineering beyond simple gaskets. Understanding the sealing technologies and materials used helps exporters communicate product value and helps buyers evaluate quality claims.

Multi-Layer Sealing Architecture: High-quality IP68 actuators employ multiple sealing layers rather than relying on a single barrier. This redundancy ensures that if one seal degrades, backup seals maintain protection ^[3]^[8].

Key Sealing Components:

Double-Sealed Bearings: Using Viton or EPDM rubber seals on both sides of bearing assemblies prevents water ingress along rotating shafts. Viton offers superior chemical resistance, while EPDM provides excellent water and steam resistance ^[3]^[9].
Epoxy Potted Electronics: Internal electronic components are encapsulated in epoxy resin, creating a waterproof barrier that protects circuit boards, motors, and sensors from moisture even if external seals fail ^[3].
AISI 316L Stainless Steel: For corrosion resistance in saltwater and harsh chemical environments, 316L stainless steel is the industry standard. This marine-grade alloy contains molybdenum for enhanced pitting corrosion resistance compared to 304 stainless ^[3]^[9].
Universal Sealing Systems: Advanced manufacturers like AUMA use non-intrusive sealing systems that allow setting adjustments without compromising the IP68 seal integrity ^[8].

Pressure Resistance Considerations: Water pressure increases by approximately 1 atmosphere (14.7 psi) for every 10 meters of depth. An actuator rated for 5 meters must withstand 0.5 bar (7.25 psi) of external pressure, while a 60-meter rated unit must handle 6 bar (87 psi). Sealing design must account for both static pressure (when submerged but not operating) and dynamic pressure variations during operation ^[5]^[9].

Corrosion Prevention Strategies: Beyond sealing, corrosion resistance is critical for underwater and marine applications. Key strategies include:

Material Selection: 316L stainless steel, marine-grade aluminum alloys, and engineered plastics (PEEK, PVDF) for non-metallic components
Surface Treatments: Anodizing, powder coating, and specialized marine paints for additional protection
Cathodic Protection: Sacrificial anodes (zinc, aluminum) for submerged installations to prevent galvanic corrosion
Regular Maintenance: Preventative treatments like CRC corrosion inhibitor sprays extend service life ^[5]^[6]

"An occasional spray of CRC prevents this [corrosion]." - Reddit user discussing marine equipment maintenance ^[5]

For Southeast Asian Exporters: When sourcing or manufacturing submersible actuators, verify that suppliers can document their sealing technology and materials. Request test reports, material certifications (e.g., 316L stainless steel certification), and IP rating test certificates. On Alibaba.com, buyers increasingly expect detailed technical documentation alongside product listings—suppliers who provide comprehensive specifications and certifications stand out in competitive searches for underwater valve and flood protection actuator solutions.

Material Standard: AISI 316L stainless steel with double-sealed bearings using Viton or EPDM rubber represents the industry standard for IP68 submersible actuators in saltwater applications ^[3].

Application Scenarios: Where Submersible Actuators Are Actually Used

Understanding real-world application scenarios helps exporters match product configurations to buyer needs. Not every application requires full IP68 submersible ratings—some can use IP67 or even IP65, reducing costs while meeting functional requirements.

Offshore Wind Farms	Saltwater, wave splash + submersion	IP68 (5m+ 96h)	Corrosion resistance, vibration tolerance, long service life	5-20 meters, continuous
Marine Vessel Systems	Saltwater, splash + occasional submersion	IP66 or IP67	Compact size, corrosion resistance, easy maintenance	Splash to 1 meter, occasional
Aquaculture Systems	Freshwater/saltwater, continuous submersion	IP68 (3m+ continuous)	Biofouling resistance, low maintenance, affordable	1-5 meters, continuous
Hydropower Facilities	Freshwater, continuous submersion	IP68 (10m+ 96h)	High reliability, remote monitoring, long service intervals	10-50 meters, continuous

Recommended IP ratings based on industry reports and technical specifications. Actual requirements may vary by specific installation conditions and local regulations ^[1]^[2]^[8]^[9].

Case Study: Hydropower Turbine Control. Pumps & Systems documented a hydropower facility using electric actuators for turbine control in continuous underwater installations. The actuators operated at significant depths with remote-mounted local controls, demonstrating the feasibility of electric (vs. hydraulic) actuation for submerged applications ^[9].

Case Study: Stormwater Management. Another documented application involved stormwater management systems in Doha, Qatar, where submersible actuators controlled flood gates during heavy rainfall events. The systems required reliable operation after extended dry periods followed by sudden submersion—highlighting the importance of seal integrity maintenance even during non-operational periods ^[9].

For Southeast Asian Exporters: Southeast Asia's geographic characteristics create strong regional demand for specific applications:

Flood Protection: Monsoon seasons and low-lying coastal areas drive demand for flood gate actuators (IP67 often sufficient)
Aquaculture: Growing aquaculture industry requires submerged valve control (IP68 for continuous submersion)
Water Treatment: Urbanization and infrastructure investment increase water treatment plant demand (IP68 standard)
Offshore Oil & Gas: Regional offshore operations require high-specification subsea actuators (IP68+ specialized)

Alibaba.com data shows Southeast Asian suppliers successfully serving both regional and global markets by matching product specifications to these application-specific requirements. When you sell on Alibaba.com, use detailed product attributes and application tags to help buyers find your products for their specific use cases.

Application Insight: Water treatment applications account for 42.1% of the submersible solenoid valves market, making it the largest single application segment ^[2].
