Component Set with Multistep Grommet Plug and Concentric Stepped Profile

Changzhou Deying Molding (Changzhou, Jiangsu, established 2010) injection-moulds multistep grommet plugs with concentric stepped profile using rubber injection moulding under IATF16949 and ISO 9001 certification at their just under 4,000 m² Changzhou facility; a specialist waterproof plug and sealing ring manufacturer, where each step diameter, flange OD, and Shore hardness are confirmed to your released dimensions requirements before shipment to verify sealing performance in the assembled connector or wire pass-through. The concentric step profile seals at multiple points along the bore, making it suitable for harness connectors that must maintain IP rating under vibration and thermal cycling. IATF16949 traceability covers automotive wiring harness, battery management system connector, and energy storage sealing ring applications. Include step diameters, overall length, Shore hardness requirement, and rubber compound in your RFQ package. For a moulding estimate from our changzhou facility.
