Complete Guide to Corrugated Loom Tubing: Types, Sizes & Uses
When it comes to protecting and organizing wires or cables in automotive, industrial, or home applications, corrugated loom tubing is a flexible, efficient, and affordable solution. Its unique design allows for superior cable management, abrasion resistance, and protection against dust, moisture, and vibration.
In this guide, we’ll explore the different types of corrugated loom tubing—such as corrugated split loom and corrugated split wire loom—as well as help you understand corrugated conduit sizes and split loom tubing sizes to make the right choice for your project.
What Is Corrugated Loom Tubing?
Corrugated loom tubing is a flexible plastic conduit designed with a ribbed (corrugated) surface. It is used to protect and organize cables and wires in various settings. The tubing’s corrugation provides flexibility, allowing it to bend and adapt to tight or complex routing spaces.
It is typically made of:
Polyethylene (PE): Affordable and durable
Nylon (PA): Higher resistance to heat, chemicals, and impact
Polypropylene (PP): Excellent chemical resistance
Flame-retardant variants: For applications requiring fire safety compliance
Common uses include:
Automotive wire harnessing
Industrial machine cable routing
Electrical installations
DIY electronics and home theater setups
Corrugated Split Loom vs. Non-Split Tubing
Corrugated split loom features a longitudinal slit along its entire length. This slit allows for easy insertion and removal of wires without disconnecting connectors or splicing cables. It’s the most popular form of corrugated tubing due to its ease of use and versatility.
Non-split tubing, on the other hand, is a fully enclosed conduit, better suited for applications where maximum protection from water, dust, or chemicals is essential, but requires wires to be fed through before terminal installation.
What Is Corrugated Split Wire Loom?
Corrugated split wire loom refers specifically to split tubing used to manage and protect electrical wiring. It is a type of corrugated split loom designed for use in electrical, automotive, and electronic projects.
Key Benefits:
Easy to install: Insert wires through the split without special tools.
Reversible: Easily remove or add wires later.
Durable: Protects against abrasion, heat, vibration, and chemicals.
Organized appearance: Improves aesthetics and reduces clutter.
It is available in multiple colors—most commonly black—for UV resistance and clean appearance, but also in red, blue, yellow, and clear for color-coded wiring systems.
Understanding Corrugated Conduit Sizes
Corrugated conduit sizes vary widely to accommodate everything from small sensor cables to thick industrial wire bundles. Choosing the right size is crucial for safety, flexibility, and proper cable accommodation.
Common Corrugated Conduit Sizes:
|
Size (ID – Inner Diameter) |
Typical Application |
|
1/4 inch (6.4mm) |
Small electronics, automotive sensors |
|
3/8 inch (9.5mm) |
Light-duty automotive, office cables |
|
1/2 inch (12.7mm) |
General-purpose wiring bundles |
|
3/4 inch (19mm) |
Larger automotive harnesses |
|
1 inch (25.4mm) |
Industrial cable groups |
|
1.5 inch (38mm) and up |
High-capacity or multi-cable systems |
Always choose a conduit size that allows a bit of clearance for cable movement and heat dissipation. Overfilling a loom can lead to overheating or damage.
Split Loom Tubing Sizes & Selection Tips
Split loom tubing sizes are typically based on their inner diameter (ID), which should be slightly larger than your cable bundle. Most suppliers list sizes ranging from 1/8" to 2" ID. Some tips to choose the right one:
Measure your cable bundle diameter, not just individual wires.
Add at least 25% extra capacity for easy installation and future expansion.
Check bend radius requirements—tighter bends may require smaller or more flexible tubing.
For example:
A 1/4" loom is perfect for 2–3 USB cables.
A 3/4" loom fits 4–6 power cables or thick automotive wires.
A 1.5" loom can accommodate multiple HDMI, Ethernet, or control cables.
Most suppliers also offer slit-resistant or high-temperature variants depending on your needs.

Reusability – Can be reused or extended with minimal waste.
Corrugated Loom Tubing FAQs
Q1: Can I use corrugated loom tubing outdoors?
A: Yes, especially if it's made from UV-resistant or flame-retardant materials like nylon. Black tubing generally offers the best outdoor durability.
Q2: How do I measure the correct conduit size?
A: Measure the diameter of your entire cable bundle and choose tubing with an inner diameter slightly larger. Refer to sizing charts or ask your supplier for guidance.
Q3: Is split loom tubing secure? Will the slit stay closed?
A: Quality split loom tubing is designed with memory that keeps the slit closed unless pried open. For extra security, you can use cable ties or tape.
Q4: Can I cut corrugated loom tubing to custom lengths?
A: Yes, you can cut it easily with scissors, a utility knife, or tubing cutters.
Q5: Where can I find a full list of corrugated conduit sizes?
A: Most manufacturers provide a downloadable catalogue or spec sheet that lists all corrugated conduit sizes and matching split loom tubing sizes. These often include compatibility charts for cable types and environmental ratings.
Whether you're managing cables in a car engine, a robotics lab, or your home office, corrugated loom tubing—especially corrugated split loom and corrugated split wire loom—offers the protection and flexibility needed to keep your wiring organized and safe. Understanding corrugated conduit sizes and split loom tubing sizes ensures you select the right solution for your project.
For best results, consult a reputable supplier's product catalogue, match your application needs with the right materials and sizes, and always allow for future expansion. Smart cable management starts with the right loom.
