5/8 in Flame Retardant Split Wire Loom Tubing - 750 ft

In this review the Electriduct 5/8 in flame retardant split wire loom is evaluated for technicians and DIYers who need heavy-duty cable protection. The bottom line: it is a long, sturdy corrugated conduit that protects harnesses from heat, abrasion and chemicals while remaining easy to work with thanks to its split design; the single biggest reason to buy is the combination of flame retardant construction and 750 ft length, which makes it ideal for large projects or stocking a workshop with reliable protective tubing.

Key Features

• Size and fit: The 5/8 in inner diameter (ID 0.603 in / OD 0.802 in) accommodates common cable bundles while warning users to measure outside diameter to ensure a proper fit.
• Long length: At 750 ft of continuous tubing, this roll supplies enough material for multiple vehicles or large industrial runs without frequent reorders.
• Flame retardant: Constructed from flame-retardant polypropylene with a UL-94 V2 rating and a continuous operating range of -40 F to 275 F for added fire safety in demanding environments.
• Split corrugated design: The longitudinal split and corrugated profile allow quick installation over existing harnesses and maintain flexibility for routing around tight bends.
• Durable protection: Resistant to heat, abrasion, vibration and many chemicals so wiring harnesses remain protected in automotive, marine and industrial settings.
• Made in Canada: Manufactured in Canada, offering consistent material quality and shape retention under stress.

Who It's For

This tubing is best for automotive mechanics, fleet maintenance shops, marine technicians and industrial electricians who need a reliable, flame-retardant conduit in bulk. Its long 750 ft supply and robust temperature tolerance make it useful for large wiring jobs, engine compartments and environments where heat and abrasion are concerns.

Those who only need a short length for occasional home use or who require a non-split, seamless conduit for pressurized or fluid-bearing applications should consider other tubing types; also measure cable bundle diameter carefully because the split design requires the bundle to be smaller than the ID to route cleanly.

Pros & Cons

Pros

• High durability and shape retention protect engine harnesses from heat and abrasion.
• Flame-retardant material and a wide operating temperature range improve safety in harsh conditions.
• Split corrugated design speeds installation and makes retrofits or repairs straightforward.
• Large 750 ft length is economical for shops and long runs.

Cons

• Requires confirming cable bundle outside diameter is less than the stated ID to ensure proper fit over larger harnesses.
• The split design may not be suitable where a seamless, watertight conduit is required.

Frequently Asked Questions

Will this tubing withstand engine compartment heat?
Yes; the flame-retardant polypropylene construction resists heat and has a continuous operating range from -40 F to 275 F suitable for many engine bay applications.

Can it be installed over existing wiring?
Yes; the split, corrugated design is specifically made to slip over existing harnesses for repairs or upgrades without disconnecting the entire run.

Is the tubing waterproof?
Not fully; the split design provides protection from abrasion and chemicals but is not a sealed, watertight conduit for submersion or pressurized fluids.
