Noise Reduction Self Closing Braided Wire Wrap Sleeving

MJ FLEX SBW-PET-NR is a self-closing braided wire wrap developed for harness routes where cable-to-panel contact can create squeak, rattle or vibration noise. Its soft-contact construction surrounds installed cables, reduces hard surface contact and remains accessible for inspection and branch-outs. Noise performance depends on installation, contact pressure and the complete vehicle or equipment assembly.

  • Why Choose SBW-PET-NR Noise Ruduction Sleeving?

    1. Reduce harness rattle

    The soft contact layer helps isolate cables from trim panels and equipment surfaces.

    2. Retrofit finished wiring

    Side entry installs around terminated harnesses without removing connectors.

    3. Maintain service access

    The self-closing overlap reopens for inspection or cable replacement.

    4. Control irregular bundles

    Flexible braid follows bends, branches and diameter changes.

     

    Key Features

    1. Noise-reduction contact surface

    Helps reduce friction and impact noise at harness interfaces.

    2. Self-closing split construction

    Wraps around cables and returns to a closed profile.

    3. Retrofit side-entry installation

    Fits completed cable assemblies.

    4. Flexible braided structure

    Follows curved and irregular routes.

    5. Abrasion protection

    Helps reduce cable-jacket wear.

    6. Accessible branch points 

    Allows local cable exits and maintenance.

    7. Custom OEM options

    Sizes, overlap, lengths and packaging can be reviewed.

    Typical Applications
    Automotive dashboards and doors 
    Reduces harness contact noise behind trim and interior panels.
    Seat and console wiring
    Contains moving accessory cables near frames and mechanisms.
    Appliances
    Limits cable movement and rubbing inside housings.
    Industrial operator stations
    Organizes serviceable wiring near covers and panels.
    Electronic equipment
    Provides soft-contact protection around sensitive assemblies.

    How to Select

    Identify the actual noise source, contact surface, vibration level and bundle range. Choose enough overlap to retain the harness without excessive compression. Validate noise reduction on the final assembly; the sleeve should not be assigned a universal dB reduction without a defined test method.

     

    Customization Available

    Diameter and overlap - Matched to cable range.

    Contact construction - Yarn and density reviewed for the noise source.

    Cut lengths - Prepared pieces for harness stations.

    Labels and packaging - OEM kits, bags and cartons available.

     

    Testing and Compliance

    Material declarations may be available for the confirmed construction. Noise reduction is system dependent and must be verified by the customer assembly test. Flame, automotive and temperature claims require supporting reports for the exact sleeve.

     

    Quality Assurance

    Yarn verification - Noise-reduction material is checked.

    Closure inspection - Overlap and self-closing behavior are verified.

    Surface check - Coverage, broken yarns and contamination are inspected.

    Release check - Length, labels and packaging are confirmed.

    Frequently Asked Questions

    01. Does the sleeve guarantee a fixed dB reduction?
    No. Results depend on the vehicle or equipment installation and test method.
    02. Can it be installed over connectors?
    Yes. It opens from the side.
    03. Is it suitable for branch-outs?
    Yes, provided adequate overlap is maintained.
