Ever wondered why your Equilibar Application Engineer recommended a Polyimide diaphragm instead of a stainless steel diaphragm? Because our back pressure
regulator has only one moving part, the choice of diaphragm selection is complex by necessity.
However, our new Diaphragm Selection page sheds a little more information on the diaphragm selection process. If you are the kind of person who likes to know “why” this
page might be for you.

Equilibar’s diaphragms come in a wide variety of materials:
Metallic Diaphragms – for high pressure and high temperatures
- Hastelloy C276
Polymer Diaphragms – for most chemical applications
- PTFE with Glass Reinforcement
- Buna N nitrile
