flexible corrugated vacuum hose 

 

1. Constitute: Corrugated vacuum hose is extruded by hard bones and muscles frame and  environmental protection material (polyether ester) hard bar.

 

2. Key size:

    Telescopic part of the external wave 2 ~ 4 mm, pitch of wave from 3 to 6 mm; Internal wave 0.5 ~ 1 mm.

 

    Recommended length is 400 mm, 500 mm, 600 mm, 800 mm, 1000 mm, 1200 mm, 1400 mm, 1600 mm , 1800 mm, 2000 mm and 2200 mm, the length tolerance is L+50 0.

 

 

 

3. Characteristics: Corrugated vacuum hose extrusion skeleton is uniform and good toughness, the surface outside pipe is bright, clean and level off, without a scratch, crack, bubble, uneven, Ge nest, lack of glue, delaminating, double skin, NingJin, efflorescence, lack of material defects etc. affect the appearance and use of performance.

 

4. Applications: Widely applied in cable casing,construction drainage,agricultual drainage,irrigation,chemical industry,medicine and ventilation ducts etc.

 

5. Mark: OEM products are welcome.
