The unit measures 11/16” at the hex section and has an overall length of 1-1/2”.
Should I replace this muffler during regular service?
Yes, replacing the purge muffler is highly recommended during scheduled preventative maintenance. A clogged or damaged muffler can impede your vacuum pump’s operational efficiency.
Do I need to check how many mufflers my unit requires?
Yes. While this part fits the PM-75, we always advise users to consult their specific equipment service manual to confirm the required quantity for your particular installation.
