Interlocked metal hose range

Convoluted Technologies manufactures its own interlocked hose by helically winding a preformed strip of 304 grade stainless steel over a nominal bore forming mandrel and folding together the adjacent edges.

Depending on the preformed shape of the strip, strip thicknesses and mandrel shape we are able to make a range of different products with a similar outside appearance. Therefore it is most important that our sales staff is fully informed about the application where the product is to be used.

Polygonal interlocked exhaust hose

Polygonal interlocked exhaust hoseOur Polygonal shape interlocked hose is made out of standard thickness material and is lightly wound, resulting in a lesser seal which is used for open-ended and low pressure applications and applications where flexibility is required.

The polygonal shape of the product prevents it from unwinding when it is cut to length. The bore range is from 1-¼ (32 mm) to 6 inches (150 mm) inside diameter. The maximum temperature rating is 600 Degrees Celsius due to the standard materials used.

We stock from 1/4” to 12” nominol bore convoluted stainless steel flexible metal hose for custom made and large bore exhaust assemblies.

Because of its design, care should be taken about the installation length and the flow direction of the interlocked hose. The length difference between fully compressed and fully extended may be as great as 20%. Interlocked hose performs best at the midpoint between fully compressed and fully extended. Keep this in mind when you need to work out an overall length of the installation. The flow direction of the interlocked hose can be checked by running your finger in the inside of the hose in fully compressed state; the right direction is the smoother surface feeling. See arrow on our illustration.

Applications: exhaust hose, flexible hose assembly armour casing, hose assembly liner, electronic shielding and cable and wire protection.

3S exhaust interlocked premium hose3S exhaust circular shape interlocked hose is made out of standard thickness material but due to the preformed strip shape we create a double wall thickness resulting in a premium exhaust hose with greater pressure seal and temperature rating.

Due to its overlapping construction it has a larger bend radius than the polygonal product.

This product will need a small weld tag to prevent it from unwinding when it is cut to length. The bore range is from 3 (76 mm) to 6 inches (150 mm) inside diameter.

Due to the double layer of material and the round shape, this interlocked hose is suitable for higher exhaust temperatures up to 700 degrees Celsius.

Applications: exhaust at higher temperatures closer to turbo, dry bulk material handling of non-abrasive media and fume and dust collection.

Stainless steel lap band exhaust clamp

Stainless steel lap band exhaust clamp to connect interlocked hose to tube.Stainless steel lap band exhaust clamps are pre-shaped to connect our interlocked hose range to solid tubing, making a simple and effective way to connect our flexible hose to exhaust system components. With this butt joint design there’s no need to separate pipes or exhaust members before clamping.

Our lap band clamps are available in standard industry tube sizes ranging from 2” (50 mm) through to 6” (150 mm). Our fastening system includes force bars, high tensile bolts, nuts, and a reaction block, which creates the power to stretch the clamp band tightly around slip joints. The reaction block provides a full 360 degree equal distribution of stretching force, preventing pipe distortion while completing a seal around the joined exhaust components.

Industrial interlocked hoseOur industrial circular interlocked hose is made out of a thicker material which makes it more resistant to abrasion and higher temperatures. The bend radius of this product is larger as the layers are tightly wound to minimise leakage through the seams. There are small indentations on the inside of the hose that prevent it from unwinding when it is cut to length. The bore range is from 1-¼ (32 mm) to 6 inches (150 mm) inside diameter. The maximum temperature rating is 650 degrees Celsius due to the heavier materials used.

Industrial Interlocked Hose


Applications: exhaust at higher temperatures, dry bulk material handling of abrasive media, fume and dust collection and flexible hose assembly armour casing where a larger bend radius is required or higher temperature protection is needed.

Because of its design, care should be taken about the installation length of the interlocked diffusion. The length difference between fully compressed and fully extended may be as great as 25%. Interlocked diffusion performs best at the midpoint between fully compressed and fully extended. Keep this in mind when you need to work out an overall length of the installation. Note other diameters can be developed on request.

• Exeeds the electrical conductivity requirements of ISO 8031

• Crush protection properties

• Suitable for jackhammer hoses

• Resistant to high temperatures• No restriction of hose bend radius

• If restriction of the hose bend radius is required use our industrial range

• Full coverage of the outer surface• Extra insulation to retain heat or

cold temperatures• Easy to apply• No tangling up in storage

This highly flexible interlocked metal diffusion armour provides crush protection for hydraulic hoses and electrical cables in most severe applications.

In test conditions the diffusion armour contained the sharp stream of hydraulic oil passing through a 1mm predrilled hole when the pressure was raised to 800 Bar and held for 1 minute with perfect fluid diffusion happening.

Installation: Cut the armour to the required length covering 50% of your crimp ferrules. To assure full flexibility make half of your length fully compressed and the other half relaxed. Trim away all sharp edges, slide it over the hose, finish crimping your hose with the armour away from the end connection, then slide the armour halfway over the crimped ferrel and attach it with medium wall adhesive heat shrink two times the length of your crimp ferrule.
