Heads up, if you use an MSA Ultra Elite respirator, the speaking diaphragm gasket can wear out over time.
This is the official replacement part, MSA part number 804809.
It's the little rubber or plastic piece that seals the speaking diaphragm so your voice comes through clear.

These are new, but they're bulk packed, so the seller will ship yours in a plastic bag to keep it safe.
It's not retail packaging, but it's the genuine part you need.

If your comms are getting fuzzy or the seal is broken, swap this out.

Cheap fix for clear communication on the job.
