Construction & Reinforcement Types
Composite Bellows
A composite bellows combines metallic components with non-metallic elements (such as PTFE or fabric layers) in a single expansion joint assembly. It's worth noting clearly: Uma Bellows' core manufacturing expertise is all-metal bellows — this page describes the general industry term for completeness, not a claim of a distinct in-house composite product line.

How it works
Composite construction is typically chosen for chemical compatibility or specific flexibility characteristics that an all-metal design can't match, at the cost of the temperature and pressure range a pure metal bellows can handle.
- Combines metallic and non-metallic materials in one assembly
- Chosen for chemical compatibility or specific flexibility needs
- Generally rated for lower temperature/pressure than all-metal bellows
- Uma Bellows' core range is all-metal — ask us about your specific media
