Buying Guide

Choose material resistant to saltwater

Polyethylene and similar marine-grade plastics resist corrosion and UV better than untreated fabrics, extending sleeve life in harsh marine environments

Match internal diameter to cable bundle

Pick a sleeve diameter slightly larger than the combined cable thickness so you can route multiple conductors without compressing insulation or stressing connectors

Prefer split loom for retrofit runs

Split wire loom styles let you add or remove wires without disconnecting components, which simplifies repairs and mid-installation changes

Check flexibility vs. protection tradeoff

Thicker-walled polyethylene offers better abrasion resistance but reduced bend flexibility—choose based on tight routing paths versus open runs

Consider visibility and tagging

Colored or high-contrast sleeve options help identify circuits quickly in bilge areas and facilitate adherence to onboard wiring documentation
