PVC Wire Reinforced Suction & Delivery Hose Previous PVC Wire Reinforced Suction & Delivery Hose

Polyurethane, often abbreviated as PU, PUR, or even TPU (Thermoplastic polyurethane), combines the best properties of plastic and rubber.

Ideally suited for dry applications only, the suction and transfer of dust, chips and abrasive particles such as wood waste and general industrial and agricultural applications.

Polyurethane (PU), a thermoplastic material useful for numerous application components, can be transmuted into different shapes; such as tubings, various types of polyurethane ducts and flexible hoses. Each kind of PU Ducting, depending on factors such as temperature resistance, chemical compatibility or plasticisers use, may perform better than the other for a particular application.

Applications, for a variety of industries; and where these standard applications include powder, granular material transfer or gasses/smoke.

Polyurethane, without using additives for retaining its flexural properties, is naturally flexible; while combining excellent chemical resistance with unique weathering characteristics. Combining excellent chemical resistance, with great weathering qualities, sets polyurethane apart from other thermoplastics; rendering polyurethane a superb material for hose and ducting. Further, polyurethane is generally more resistant to pressure and vacuum applications than corresponding sizes of PVC or rubber; and moreover, it is also more abrasion-resistant than most other thermoplastics.

TEMPERATURE RATING

This product is rated for general use at -40°C to + 90°C which covers use for all general applications for this product, however in some cases you may need this for hotter applications for shorter periods of time, for these instances we recomend using the product up to + 125°C.

Material

The hose is made from lightweight medium duty PVC, giving it Excellent resistance to tearing, oils, fats and several solvents, while making it a light product that can be easily handled and stored.

REINFORCEMENT

With a copper coated steel wire helix, this product has excellent flexibility and elasticity even at low temperatures. The reinforcement means you bend the product to any angle you like without this kinking.

 

WALL THICKNESS

This product has a 0.4mm wall thickness on all diameters, thin enough to allow the product to be flexible but also thick enough to make this a sturdy product when in use and not allowing for this to be punctured easily.

MAX LENGTH

The max length of this product is 10 metres, this is achieved when the product is at full stretch. The comressed length of the product is around 10% of the stretched length.

APPLICATIONS

Suction and transportation of sawdust and wood splinters, cereals, granulates, abrasives, solids and fumes in the woodworking and pharmaceutical industries.

 

How To Measure

The Product

When measuring for this product, you need to measure the outside diameter of the outlet that this shall be going over, this is the measurement needed for the internal diameter of the product, please note this product does have a 3mm stretch and can also be clamped down by 3mm.

Always measure the hose by the internal diameter. This is measured from the inside of the wall directly across to the inside of the wall on the other side.

For a clip

When measuring this product for a clip, you need to take into the account the wall thickness of the product. This specific product has a 0.4mm wall thickness on all sizes.

Still unsure which clip to get? We do have a clip guide available, this is located next to the details tab above. This will take you directly to the correct clip for you.

The Length

This product is measured when the product has been stretched to its maximum length, therefore when measuring please make sure you have taken this into account.

When the item arrives this shall come as the compressed length.

frequently asked questions

 
q: What clip would best suit this ducting?

We would recommend the Worm Drive Clip for this product.

PLEASE NOTE - Take the outside diameter of the ducting for the clip. Please see the "Technical Specification" for the outisde diameter of the "Clip Guide" for links to specific clips for the hose.

 
q: How is the length measured?

We measure this product when it has been stretched to the maximum length, when ordering please take this into account.

 
q: Do you supply lengths longer than 10 Metres?

Currently we only sell this in a maximum length of 10 metres, if you require a longer length we recomend purchasing two lengths and connecting them together using an Aluminium Hose Joiner, along with some Worm Drive Clips

 
q: I am wanting a length that you don't list?

This product comes into a maximum lenth of 10 metres, if you require a lenght shorter than this please select the 1 metre length and the qty you require.

For example if you require a 6 metre length, please choose the 1 metre length and then a quantity of 6.

 
q: Will the ducting collapse under vaccum?

No, this hose is built for applications that required vaccum such as dust extraction systems and suction of wood shavings, sawdust, light solid materials, etc..

However this is completely dependant on the pressure running through the hose, for more informaiton please see our "Technical Specification".

 
q: Is this food safe?

Yes, this is a food approved product. This is suitable for food products for which no migration tests are required: solid dry-foods.
