Advantages

Very resistant and light, SPIRABEL® P.U.A2 is ideal for transporting abrasives: its entirely smooth interior avoids deposits forming and the top-quality polyurethane used offers excellent abrasion-resistance.
It has outstanding mechanical qualities: it easily withstands repeated flexing and has good suction-holding properties at temperatures up to 80°C. SPIRABEL® P.U.A2 is transparent, allowing easy monitoring of product circulation.

Fittings

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 the chemical resistance table in column C.

Warning

Spiral hoses have in general 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.
