Cable Assembly
Custom waterproof wire harnesses with IP67, IP68, and IP69K ratings for marine, automotive, industrial, and outdoor applications. IATF 16949 discipline and in-house IP testing per IEC 60529 / ISO 20653 — overmolded, potted, and marine-grade sealed constructions.
Application Context
Waterproof wire harnesses are custom cable assemblies engineered with specialized sealing methods, water-resistant materials, and IP-rated connectors to prevent moisture ingress and protect electrical systems in wet, dusty, or harsh environments. General-purpose hook-up wire and unsealed connectors fail in those conditions — so a waterproof harness uses sealed connector interfaces, marine-grade tinned copper, UV-resistant jacketing, and a permanent moisture barrier from the start, all validated to an IP67, IP68, or IP69K rating per IEC 60529 standards.
We manufacture complex, high-IP-rated custom waterproof wire harnesses for demanding B2B applications — not simple extension cords or commodity outdoor cables. Our expertise covers IP67/IP68/IP69K assemblies built with overmolded connectors, potting and marine-grade materials, including environmentally sealed-splice joints, sealed Deutsch DT/DTM terminations, and saltwater-ready marine audio constructions. Every waterproof wire harness includes in-house IP rating testing and certification per IEC 60529.
Manufacturing Capabilities
IATF 16949-disciplined facilities with an in-house IP testing lab manufacture custom waterproof cable assemblies from IP65 to IP69K for marine, automotive, and industrial applications.
Multiple proven sealing approaches selected against immersion depth, washdown pressure, and serviceability.
Marine-grade conductors and jacketing chosen for corrosion, flex, and UV exposure.
Protection against salt, chemicals, UV, abrasion, and flame for harsh service.
A wide build envelope across gauge, voltage, current, temperature, and length.

Engineering Challenges
Choosing overmold, potting, gland, or gasket sealing against immersion depth, washdown pressure, and whether the assembly must stay serviceable.
Proving IP67, IP68, or IP69K performance per IEC 60529 / ISO 20653 with hydrostatic, high-pressure-jet, and dust-ingress testing before production.
Salt spray, UV, chemical, and thermal exposure that degrade unsealed harnesses — addressed with marine-grade wire, UV jackets, and tinned copper conductors.
Permanent sealing cannot be field-repaired, so serviceable gasketed connectors are planned up front where field maintenance is anticipated.
Technical Capabilities
IATF 16949 and IPC/WHMA-A-620 manufacturing with sealed connector systems, validated from IP65 to IP69K for marine, outdoor, industrial washdown, and automotive service.
Manufacturing Process
Quality & Testing
Every custom waterproof wire harness undergoes IP rating validation, environmental testing, and electrical verification in our accredited lab before shipment — documented per IEC 60529 and ISO 20653 for lot-level traceability.
