1/8 Inch Split Loom Tubing

The Wires Zone ST18-50 is a 50 foot coil of black polyethylene split loom tubing with a 1/8 inch diameter. It is designed to organise and protect wire bundles in automotive, marine, and industrial environments. The split design allows easy insertion of cables while remaining closed when bent or twisted. Uniform extrusion thickness provides consistent protection along the full length.

Installers Needing Abrasion Resistance

This tubing suits technicians who need to shield wiring harnesses from abrasion and crushing in tight spaces. The smooth exterior finish helps it slide through firewall grommets and conduit without snagging. It is not intended for builders who require larger diameter conduit for thick cable bundles or high-temperature rated sleeving for engine bay exposure.

Flexible Wire Management Coil

The 50 foot length lets you cut custom sections for multiple vehicle circuits without joining short pieces. Polyethylene construction resists common automotive fluids and remains pliable in cold weather. It frees up installation time by eliminating the need for tape or zip-tie bundling on individual wires. The split seam stays shut around corners, keeping the loom intact during vibration.

Questions about this item

What wire bundle size fits inside the 1/8" split loom?

The 1/8" inner diameter suits small-gauge automotive or marine wire bundles that measure up to roughly 3 mm across.

Will the polyethylene tubing stay flexible when routed next to older PVC-insulated harnesses?

Yes, the smooth polyethylene remains pliable at typical engine-bay temperatures and will not stiffen or react chemically with legacy PVC jackets.

How can I confirm the loom is protecting the wires correctly after installation?

Run the harness, then inspect the full 50 ft length — wires should sit fully inside the slit, the split should stay closed on bends, and no conductor insulation should be visible through the black polyethylene wall.
