Corrugated metal hose assemblies

Advantages

Can work at very low (-250°C) up to very high (+550°C) temperatures, depending on the conveyed fluid.
Highly resistant to temperature changes.
Exposure to high heat, fire, abrasion, corrosion and mold. Use under high pressure or vacuum. Vibration absorption.

Optional services:

Electrical tracing to maintain or warm the fluid being transferred.
Double-jacket to maintain the temperature of the fluid being transferred.
Tapping to take a temperature reading or sample of the fluid being transferred.
