Frequently Asked Questions

Is the 680455 muffler compatible with my Ingersoll Rand equipment?

The 680455 is an Ingersoll Rand muffler for compatible compressed air equipment and dryer applications. Compatibility should always be confirmed by matching 680455 in your equipment manual and verifying the model, serial number, thread size, muffler location, airflow direction, and pressure rating before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 680455 muffler do?

The 680455 helps reduce noise from vented or exhausted compressed air. Depending on the equipment configuration, it can help:

  • Reduce exhaust or purge-air noise
  • Promote smoother discharge airflow
  • Help control noise during dryer or pneumatic-system operation
  • Protect surrounding work areas from excessive venting noise
  • Support proper compressed air system operation

Why is replacing the 680455 important?

A properly functioning 680455 helps maintain:

  • Reduced operating noise
  • Proper exhaust or purge airflow
  • Lower restriction at the muffler location
  • More reliable compressed air system performance
  • Better protection for connected air-treatment components

A clogged, damaged, oil-soaked, corroded, or missing muffler can increase noise, restrict venting, or affect the connected system’s ability to exhaust air properly.

What are the signs that the 680455 muffler may need replacement?

Common signs include:

  • Louder than normal purge or exhaust noise
  • Restricted exhaust airflow
  • Muffler body corrosion or damage
  • Oil, moisture, or debris buildup in the muffler
  • Cracked, loose, or missing muffler
  • Air dryer purge issues related to exhaust restriction
  • Repeated clogging from contamination
  • Muffler no longer threading securely into place

These symptoms can also be caused by purge valve problems, contamination upstream, drain issues, or other air-treatment faults. Inspect the full system before replacing only the 680455.

Is this an OEM part?

This is an OEM-equivalent replacement muffler designed to meet the same performance standards as the original Ingersoll Rand muffler.  

How difficult is it to install?

Installing the 680455 is generally a simple to moderate maintenance task, depending on access and system condition.

Before service, the equipment should be:

  • Fully shut down or isolated
  • Completely depressurized
  • Electrically locked out if required
  • Cooled to a safe working temperature
  • Drained of condensate if applicable
  • Verified so no stored pressure remains at the muffler location

Installation typically involves removing the old muffler, inspecting the exhaust port and threads, installing the replacement 680455 without over-tightening, and confirming proper exhaust airflow and noise reduction after startup.

Do you carry other parts for Ingersoll Rand?
