Coats 85607855 1/4" NPT Small Muffler - OEM Replacement

When your bead loosener arm or pedal 4-way valve assembly starts getting louder than it should, this is the part you need. The Coats 85607855 is a direct OEM replacement muffler with a 1/4" NPT connection that handles both noise reduction and airflow regulation at the valve assembly. No guesswork, no adapters, no modifications required.

It's confirmed compatible with Coats GTS, RC, X-Series, and Baseline tire changers. OEM spec means the fit is exact and the function is what the machine was built around. You're not improvising with an aftermarket part that's "close enough" - you're putting back exactly what Coats intended. That matters more than it sounds. A muffler that doesn't seat correctly against the valve port can affect airflow regulation, which shows up as inconsistent bead loosener behavior during a tire change. Get the real part and that's not a variable you're dealing with.

If your machine is cycling louder or behaving inconsistently at the bead loosener pedal, start here. It's a small part, but it's doing real work every time that valve fires. We stock OEM Coats replacement parts so you're not waiting on a special order when the machine goes down mid-day.
