CONVOLUTED PTFE HOSE ASSEMBLIES|Trelleborg Fluid Handling Solutions

Applications

For transfer of extremely hot or cold fluids, aggressive and corrosive chemicals, in demanding environments.

Resistant to almost any chemicals. Can work at very low (-70°C) up to very high (+260°C) temperatures, depending on the conveyed fluid.

Very flexible and light weight, resistant to flexion.

Overview

Inner tube

Helically convoluted PTFE, white or black (antistatic), compliant with FDA 21 CFR 177.1550, USP Class VI requirements, and EU regulation 1935/2004

Braid(s)

High tensile 304 stainless steel or polypropylene.
Other qualities, like PVDF, or finish, like EPDM or silicone coating, upon request.

Temperature range

-70°C to +260°C

Couplings and Fittings

Made to order with any types of fittings, stainless steel or PTFE coated, including flare through ends for flanges.

Electrical properties

White = Type M : R< 100 Ω between couplings with stainless steel braids
Black = Type Ω : 1K Ω < R < 100M Ω
