Fabric Expansion Joint

Totflex fabric expansion joints are advanced flexible connectors designed to absorb combined thermal, mechanical, and installation-induced movements in ducts and piping systems transporting hot gases, air, or corrosive media. Totflex joints ensure safety, uptime, and long-term reliability in power, process, and heavy industries.

Totflex fabric expansion joints deliver reliability where it matters most—under demanding process conditions.

Designed for Real Movement: Handles axial, lateral, radial, and angular movements—protecting your ductwork from fatigue and stress failures.

Unmatched Chemical and Thermal Defense: Built to withstand extreme heat and corrosive process gases thanks to tailored multi-layer construction.

Low System Stress: Transmits minimal force to connected equipment, helping you avoid costly downtime from mechanical strain.

Precise, Custom Engineering: Every joint is sized and layered for your application—no off-the-shelf compromises, just the right fit.

Fast Installation, Simple Maintenance: Flexible, lightweight design cuts down on install time and makes future inspections straightforward.

Quality You Can Trust: Certified to ISO, PED, FSA, and EJMA standards, with material and test traceability on every order.

- Axial : Compression and expansion along the duct axis
- Lateral: Sideways movement perpendicular to axis
- Radial: Circumferential expansion/contraction (diameter change)
- Angular: Bending or misalignment between flanges
- Torsional: (If required) Limited twisting motion

- Clamped (direct to duct)
- Bolt-on/Flanged
- Weld-in
- Endless or split for field closure
- Special cuffs for high pressure or temperature available.

- Standard: Round, Rectangular, Oval
- Special: Snouts, elbows, transition shapes, or fully custom per application
