It is recommended especially when a smaller bending radius is required; an even smaller bending radius can be achieved compared with the standard 650/V. These hoses are able to transport liquid or semi-liquid foodstuffs at high temperatures by impulsion or suction, since their design can resist pressure or vacuum
Properties
- Odourless, tasteless and completely non-toxic.
- Translucent and smooth inner appearance, white or coloured and smooth outer appearance.
- Special silicone, formulated by Venair®, with excellent elastic properties.
- Very low bending radius; more than two times flexible than standard 650/V.
- Can be equipped with 316L stainless steel fittings on each end with a roughness value of less than 0.8 (or 0.5 on request).
- Operational temperature range from -60ºC (-75ºF) to +180ºC (356ºF), it may reach up to +200ºC (392ºF) during short periods of time.
- The standard manufacturing length is 4 meters long (13.12 ft.), but in specific diameters, a length of 6 meters (19.69 ft) can be manufactured.
- The vacuum resistance for this hose is 0.91 Bar (13.23 psi).
Limitations
Respect the bending radius and work pressure established values.
Mind the chemical compatibility of the fluid with the silicone.
This product is not recommended for the transport of abrasive particles
Regulations

Technical Specifications
Construction
This reference is manufactured with three polyester fabric reinforcements and a stainless steel wire spring, everything encased inside the hose.
SIL 650/V AC: The hoses are equipped with a copper wire fitted parallel to the stainless steel wire spring to improve static electricity discharge1.
1. The hose must be properly earthed to allow the current dissipation of the static charge, earthling the hose metallic fittings or directly the copper wire of both ends of the hose.
Use Precautions
- Extreme working conditions or the use of materials with low compatibility with silicone can attack the inner surface of the hose. It is advisable to inspect the inner appearance for cracks or swelling, and replacement of the hose, if necessary.
- Hose cover: Should be inspected over the entire length for signs of hardening, abrasion, cuts, kinking or crushing
