Kokey-xy Tinned Copper Braided Sleeve 1/4-in Flat Width, 9FT – EMI/RFI Shielding & Grounding Mesh

Overview

Meet the Kokey-xy Tinned Copper Braided Sleeve, a flexible metal wire loom designed to shield cables and bundles from interference while offering dependable grounding options. Woven from 0.12mm oxygen-free tin-plated copper wire, this sleeve balances durability with pliability, so it can follow tight bends and dense routing without kinking.

Its flat, 1/4-inch width and tubular inner diameter of 5/32 inch deliver a compact profile for many harnesses, while the 9-foot length supports longer runs or multiple bundles in one install. The tin plating enhances oxidation resistance compared to untreated copper, helping to maintain shielding performance in varied environments.

Key benefits at a glance

• EMI and RFI shielding: The braided metal weave forms a conductive shield that can reduce interference and preserve signal integrity on sensitive lines like data and video cables.
• Electrostatic protection and grounding: The sleeve is suitable for grounding and earthing needs, helping to channel surges away from equipment when used as a dilatation joint between conductors.
• Durable yet flexible: The tubular, mesh-wall construction is designed to be expandable and abrasion-resistant, guarding wires against wear from movement and routing through confined spaces.
• Broad applicability: With use cases spanning automotive, aerospace, high-speed trains, and industrial harnessing, it is commonly used across power and data lines, HDMI and video lines, and multi-cable bundles.

Applications and use cases

• Automotive: shield and ground harnesses in engine bays, dashboards, and under-hood electronics.
• Industrial and rail: protection for power and control cables in high-speed systems and underground installations.
• Electronics and AV: safeguarding HDMI, USB, and computer power cables from interference in densely packed enclosures.

How you expect to use it will shape the installation: plan where to place the sleeve, ensure a snug fit around your bundle, and allow for bend radii and routing that preserve shielding performance. This sleeve can be cut to length and wrapped around wires to provide a shielded layer without replacing existing harnesses.
