Explore our waterproof industrial connector range

When performance depends on resisting liquids, dust and pressure washing, choosing the right connector transforms reliability across the whole system. WEIPU’s waterproof portfolio spans circular, heavy-duty and CEE styles with tailored sealing geometries, multiple mounting options, and contact layouts designed for signal, power and mixed-service applications. Rather than one-size-fits-all parts, WEIPU provides over 70,000 specifications to match form factor, current capacity and environmental requirements.

Circular connectors with IP65–IP69K sealing for outdoor and washdown environments.
Heavy-duty multipin connectors engineered for vibration and splash-prone industrial installations.
High-current solutions up to 800A for energy storage, EV charging and heavy machinery.
Medical-grade connectors proven to withstand 134°C autoclave cycles for sterilisation processes.

Each family is designed to simplify integration—standardized panel cutouts, keyed housings to prevent mis-mating, and flexible cable entry options—so engineers spend less time adapting and more time delivering systems that survive real-world exposure to water, chemicals and thermal cycles.

Why waterproof connectors from WEIPU matter in your projects

Water ingress is a leading cause of field failures in industrial equipment. A properly specified waterproof connector reduces downtime, lowers lifecycle costs, and protects sensitive electronics from corrosion and short circuits. WEIPU connectors are built to address those risks directly: they combine robust mechanical design, resilient elastomer seals, and dependable contact metallurgy to preserve electrical continuity under repeated wet/dry cycles.

For procurement and design teams, this means measurable benefits:

Increased uptime in washdown and outdoor installations.
Lower maintenance and spare part inventories due to predictable, long service life.
Regulatory and safety alignment when deployed in medical, automotive and rail applications.

By selecting a waterproof solution up front, system architects can reduce field service interventions and mitigate costly recalls or in-service failures.

Design philosophy, certifications and support you can trust

Founded in 1996, WEIPU is a principal drafter of the GB/T 11918-2014 national standard and a trusted supplier to 30,000+ customers in 130 countries. Our 2025 expansion increased capacity to an 80,000 m² facility capable of producing 55 million units annually. That scale is matched by strict quality governance—WEIPU holds IRIS (Rail Transit) and IATF 16949 (Automotive) certifications—and by vertically integrated manufacturing that keeps design iterations fast and controllable.

Practical advantages delivered to customers include:

Independent R&D and tailored OEM/ODM development with prototypes in 7–15 days.
A 24-hour rapid response channel for technical queries and sampling.
Tested environmental performance such as IP69K-rated sealing and medical-grade autoclave resistance to 134°C.

Whether you need a standard waterproof connector or a custom assembly with specific sealing compounds, plating or cable harnessing, WEIPU’s one-stop solution reduces supplier complexity while ensuring products meet the most stringent global safety standards.

FAQ

What does "waterproof" mean for WEIPU connectors and which IP ratings are offered?

For WEIPU, "waterproof" refers to connector designs with sealed interfaces that prevent liquid ingress under specified conditions. WEIPU designs include products with industry-leading ingress protection, including IP65 through IP69K ratings. IP69K-rated connectors are engineered for high-pressure, high-temperature washdown environments and are suitable where steam cleaning and aggressive washdown procedures are used.

Can WEIPU waterproof connectors be used in medical or sterilisation environments?

Yes. WEIPU provides medical-grade connector solutions explicitly engineered to withstand autoclave sterilisation cycles up to 134°C. These products combine biocompatible materials and sealing details that preserve electrical integrity after repeated sterilisation, making them suitable for many medical devices and laboratory equipment.

How do I choose the right waterproof connector for outdoor or washdown applications?

Select based on environmental exposure, electrical requirements and mechanical constraints. Key criteria include the required IP rating (e.g., IP67 versus IP69K), current and contact count, vibration and strain expectations, and the need for mixed power/signal contacts. WEIPU’s broad catalogue—over 70,000 specifications—plus engineering support helps map application needs to the optimal family and sealing solution.

Does WEIPU offer customization and what are typical lead times for prototypes and production?

WEIPU provides OEM/ODM services with rapid development workflows. Prototypes can be delivered in 7–15 days, supported by a 24-hour rapid response system for technical queries. With vertically integrated manufacturing and an 80,000 m² facility capable of 55 million units annually, WEIPU scales from small custom runs to large-volume production while maintaining traceability and quality control.

How are WEIPU waterproof connectors tested and certified for reliability?

WEIPU subjects connectors to environmental and mechanical tests that validate sealing, temperature resistance and electrical performance. This includes ingress testing to IP standards (up to IP69K), autoclave cycles for medical variants, and mechanical endurance tests. WEIPU’s processes are governed by IRIS and IATF 16949 certifications, ensuring consistent quality for rail, automotive and other regulated industries.
