ARO 67445-2 AFX Muffler Kit

ARO 67445-2 is an AFX muffler kit from ARO (Ingersoll Rand). The catalog notes describe it as a 363 piston pump part. A muffler mounts where spent air leaves the air motor and cuts the sharp sound of each exhaust pulse.

The record gives no material or list of contents. Order by the complete number with the -2 suffix, and compare it with the parts list for your pump. Note how the old muffler sits before removal so the new one goes back the same way.

When to Use This Kit

• The pump is noticeably louder at exhaust than it used to be.
• A restricted muffler is slowing the pump cycle.
• The old muffler body is cracked or loose on its port.
