Omega U-Flex Expansion Joints

Omega U-Flex is a flexible loop made of two parallel braided metal hoses joined by a U return, absorbing movement in all directions at building joints and moving connections.
It is used at building joint crossings, fire systems, heating-cooling and equipment connections. The product range includes flanged, weld neck and grooved models from DN25 to DN200 in 40 mm and 100 mm movement series.
Main Applications
- Building joint crossings
- Fire system joint crossings
- Heating and cooling lines
- Tank and equipment connections
- Lines in seismic zones
- Flexible crossings in tight spaces

Material Options
| Part | Omega U-Flex | Omega V-Flex |
|---|---|---|
| Geometry | Parallel legs with U return | V-shaped legs |
| Movement | Multi-directional | Multi-directional |
| Connection | Flanged, welded, grooved | Flanged, welded |
| Typical use | Large lateral movement, joints | Compact spaces, joints |
Which material? Omega elements absorb joint movement by flexing their legs; hangers and supports should be planned to allow free movement of the U return. Pressure and temperature ratings are verified for the chosen element.
