The three-electric system (battery, motor, high-voltage wiring) forms the core of every new energy vehicle, and tiny sealing failures on connectors and equipment shells often trigger major safety hazards like short circuits, water intrusion and component aging. Professional New Energy Vehicles Rubber Parts are engineered to eliminate these hidden risks, with two all-purpose EPDM sealing accessories dominating mass orders from EV OEMs and component manufacturers: Cable Tail Sealing Rings for NEV Connectors and EPDM Rectangular Sealing Rings fit various shell components of new energy vehicles.

Cable Tail Sealing Rings for NEV Connectors serve as the critical sealing barrier at the outlet of all high-voltage wiring connectors. NEV power cables carry high current and run through chassis gaps exposed to rain, road salt, dust and extreme temperature swings. Without tight tail sealing, moisture and fine metal debris will creep into connector terminals, causing oxidation, poor contact or even electric leakage. Molded from modified EPDM with strong elastic recovery, these rings closely wrap around cable outer jackets, achieving IP68 dustproof and waterproof performance. They resist coolant, ozone and UV radiation, maintaining consistent clamping elasticity from -40℃ to 130℃ without hardening or shrinking. Flexible sizing supports all mainstream high-voltage connector specifications for passenger EVs, commercial electric trucks and energy storage equipment, greatly reducing wiring system breakdown rates.

EPDM Rectangular Sealing Rings fit various shell components of new energy vehicles are universal flat gaskets customized for battery packs, motor housings and electric control box enclosures. Rectangular shell gaps are common on all NEV core equipment, and ordinary thin gaskets easily lose tightness after repeated thermal expansion and contraction. These EPDM rectangular rings feature uniform compression resistance and low permanent deformation, perfectly filling assembly clearances between metal and plastic shells. Their multi-functional formula delivers insulation, corrosion resistance and flame retardancy, blocking dust, condensed water and chemical mist from invading internal precision parts. One mold can produce adjustable lengths to match diverse shell sizes, cutting mold development costs for component factories significantly.

Complementary rubber accessories such as battery rubber pads and high-voltage dust caps form a full sealing solution together with the above two core products. All NEV rubber sealing parts pass strict salt spray, aging and compression testing under IATF 16949 standards. Custom rubber hardness, thickness and flame-retardant formulas are available to match unique assembly requirements. If you are sourcing reliable, long-service-life NEV rubber seals for mass production or prototype testing, customized samples and bulk supply can be provided to stabilize your component quality and lower long after-sales costs.
