Hot, cycling, and usually vibrating as well. Exhaust is where interlock earns its place, and where getting the movement right matters more than getting the material exotic.
Applications and the products that suit them
| Application | Product |

| Generator set exhaust connections | Interlock hose in 321, braided |
| Engine exhaust flexible connections | Interlock hose with end fittings |
| Boiler flue gas ducts | Axial expansion joint with internal liner |
| Chimney and stack expansion | Axial expansion joint in 321 |
| Turbocharger connections | Braided corrugated hose in 321 |
| Exhaust gas recirculation | Braided corrugated hose in 321 |
| Silencer and catalyst connections | Interlock hose braided |
Specification notes for this sector
- 321 for sustained exhaust temperature — 304L and 316L will sensitise
- Exhaust connectors take thermal growth and vibration together; size for both
- Braid over interlock where the connector also carries tensile load
