Manufactured from high quality soft PVC with a galvanized steel spiral, Spire Acier is highly resistant to vacuum and crushing. The transparent wall is UV resistant and allows easy visual control of the fluid and identification of blockages. The smooth inner wall reduces flow losses and enables easy cleaning. Spire Acier is suitable for food contact applications up to 40°C. Alcohol beverages up to 50% alcohol content can also be conveyed up to 40°C.


Guillemin or Storz symmetrical connectors, cam or universal joint connectors – Fastened with single-thread or spiral clamps (SERFLEX).
Crimping and band clamps are not recommended as they do not ensure a perfect seal and increase the risk of the spiral being crushed and breaking.

Chemical resistance

See table pages 104 to 107 column A.


Spiral hoses in general have an elongation under pressure that can be important when temperature is above 40°C. This has to be considered before installation. We remain at your disposal for any question on this issue.
