Key Features

Protective Grommets for Wires and Cable Openings

Our rubber wire grommets are designed to protect cables from sharp edges, reduce vibration damage, and seal openings in different equipment housings. Custom compounds, hardness levels, and hole structures are available according to drawings or samples.

  • Wire Opening Protection

    Helps protect wires and cables passing through panels, housings, or equipment openings.

  • Smooth Molded Surface

    Smooth surface with a small parting line helps improve appearance, fit, and installation consistency.

  • Custom Hole Design

    Single-hole, multi-hole, and special opening designs can be customized for different wire routing needs.

  • Wide Hardness Range

    Available from 10 to 90 Shore A to support flexible sealing, cable protection, or more rigid positioning.

  • IATF 16949 Quality Support

    IATF 16949 certified production support, with inspection standards available under AQL 1.0 / 0.65 / 0.15 and C=0 zero-defect requirements.

  • In-House Tooling Capability

    In-house tooling with 24-hour CNC machining support helps reduce mold cost and shorten custom development time.
