Expandables & Diaphragms

Request More Information ›

Federal now offers new and improved level filler valve diaphragms & expandables.

These parts are updated and improved versions of the expandables and diaphragms you have been using for years.

And, we’re very pleased to announce that in addition to the traditional red parts, we’re now offering them in blue.

We are using the same part numbers for these items to make the transition to the new and improved versions seamless and easy.

While the part numbers remain the same, the parts are better than ever.
