Learn when and how to use DeatschWerks Convoluted Tubing (250mm x 10mm) to protect fuel hoses from abrasion and heat. Includes fitment guidance and installation rules.
Quick answer
For protecting fuel hoses in tight engine bays or near abrasive surfaces, DeatschWerks Convoluted Tubing (250mm x 10mm) provides a simple, low-cost sleeve that slips over lines to guard against chafing and minor heat exposure.
Why protect fuel hoses with convoluted tubing
Fuel hoses routed near sharp edges, brackets, or moving parts are vulnerable to abrasion that can cause leaks. A protective sleeve like convoluted tubing adds a durable layer between the hose and potential damage points.
This 250mm length is ideal for short exposed sections, such as where a hose passes through a bulkhead or near a fuel pump bracket. The 10mm inner diameter fits many standard 5/16" and 3/8" fuel hoses snugly without excessive play.
Trade-offs to consider
At 250mm, this tubing is not designed to cover long hose runs. For full-length protection, you would need multiple pieces or a longer continuous sleeve.
The 10mm inner diameter is fixed. Hoses larger than 3/8" (e.g., -6 AN or -8 AN) may not fit, and smaller hoses (e.g., 1/4") may have too much movement inside the sleeve, reducing protection.
Decision rules for using convoluted tubing
- Measure your hose outer diameter: Use a caliper to confirm the hose OD is between 9mm and 10.5mm. The 10mm ID sleeve will slide on with light friction. If the hose is larger, the sleeve may not fit; if smaller, the sleeve may shift. Test fit a short section before cutting or securing.
- Identify the vulnerable zone: Look for spots where the hose contacts a sharp edge, bracket, or moving part. Common areas: near fuel pump mounts, through chassis holes, or where hoses cross over engine components. Mark a 250mm or shorter section. Do not use the sleeve where the hose bends sharply—it can kink inside the tubing.
- Install before final routing: Slide the convoluted tubing onto the hose before attaching the hose ends. If the hose is already connected, you may need to cut the sleeve lengthwise and wrap it, but a split installation reduces protection. For best results, install during assembly. Secure the sleeve with zip ties or heat-resistant tape at both ends to prevent movement.
Product facts
- Convoluted Tubing, 250mm Length x 10mm: DeatschWerks Convoluted Tubing is a black protective sleeve with a 250mm length and 10mm inner diameter on both sides. The 10mm ID is sized to fit common 5/16" and 3/8" fuel hoses, and the 250mm length covers short vulnerable sections without excess material.

Fit guidance
Best for
- Protecting short exposed sections of 5/16" or 3/8" fuel hose near brackets or sharp edges
- Adding a protective layer during a fuel pump or fuel system installation where the hose passes through a chassis hole
Not for
- Long continuous hose runs (over 250mm) where a longer sleeve or wire loom would be more practical
- Hoses larger than 3/8" OD (e.g., -6 AN or larger) that will not fit inside the 10mm ID
