Why Choose WIRES?
Unparalleled Manufacturing Capability
Based on your application requirements, we manufacture waterproof cable assemblies using multiple termination and sealing methods, supporting protection levels up to IP67/IP68 and operating environments typically ranging from -40°C to 105°C.
For overmolded connectors, we utilize:
- High-strength waterproof plugs to ensure sealing between conductors, cable jackets, and connectors
- O-rings and pre-installed sealing gaskets to enhance ingress protection
- Optimized overmolding processes for improved mechanical strength and long-term durability
For non-molded assemblies, we provide:
- Cable connectors with diverse sealing solutions, including USB, RF, circular, and D-sub interfaces
- Potting (resin sealing) techniques for enhanced moisture and dust resistance
- Panel-mount connectors compatible with sealing gaskets to achieve IP-rated enclosure protection
We begin by thoroughly understanding your requirements and collaborating closely during the prototype development stage to validate design feasibility. This ensures the cable assembly maintains stable performance and sealing reliability in harsh environments such as moisture, dust, vibration, and temperature variations.
WiresFab provides a wide range of custom cable assemblies tailored to your requirements, including cable lengths (50 mm–10 m+), insulation types (PVC, TPE, silicone), waterproof connector options (IP67/IP68), and shielding configurations (foil, braid, or hybrid).
Our solutions support diverse industries such as consumer electronics, automotive, motorcycles, and medical applications, ensuring reliable performance across different use environments.
We strictly follow approved prototype samples throughout production and perform rigorous quality testing, including 100% continuity checks and visual inspections, to ensure every wiring harness delivered matches the validated design.
We support both low-volume prototypes and high-volume production to meet different project stages. For large orders, we offer phased deliveries and scheduled shipments to help reduce inventory pressure and support your supply planning.

Frequently Asked Questions
Wires provides waterproof cable assemblies with protection levels such as IP67 and IP68, designed to prevent the ingress of moisture and fine particles for reliable operation. Higher protection solutions can also be developed based on your specific application and environmental requirements.
When designing waterproof wiring harnesses, the following key factors should be considered to ensure reliable sealing and long-term performance:
- Waterproof connectors: Selection of connectors with appropriate IP ratings (e.g., IP67/IP68)
- Sealing methods: Use of O-rings, gaskets, potting (resin sealing), or other waterproof techniques
- Harness structure: Choosing between semi-encapsulation or loose routing based on application needs
- Installation design: Proper routing and mounting to avoid stress, gaps, or water ingress points
- Wire processing: Cutting methods, stripping quality, and whether twisting or shielding is required
- Termination sealing: Use of waterproof plugs, overmolding, or sealed terminals at connection points
Yes, Wires supports prototype and sample orders to enable testing and validation before mass production. We have delivered samples to 200+ customers, helping verify sealing performance, fit, and reliability to ensure the waterproof cable assemblies meet your requirements.
