Frequently Asked Questions

Is the 123157-373 O-ring compatible with my Quincy compressor?

The 123157-373 is a Quincy reservoir sealing O-ring used on compatible Quincy rotary screw compressors. Always verify 123157-373 in the compressor parts manual and confirm the model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What is the Quincy 123157-373 O-ring?

The 123157-373 is a large O-ring used to seal the compressor reservoir cover / oil reservoir assembly on compatible Quincy rotary screw compressors.

It helps maintain a tight seal in the pressurized air/oil reservoir system.

Why is the 123157-373 O-ring important?

A properly sealing 123157-373 helps:

  • Maintain reservoir pressure
  • Prevent compressed-air leakage
  • Prevent compressor oil leakage
  • Keep contamination out of the reservoir joint
  • Support reliable separator and lubrication-system operation

What are the signs that the 123157-373 O-ring needs to be replaced?

Common signs include:

  • Compressor oil leaking around the reservoir cover
  • Oily residue around the reservoir joint
  • Audible compressed-air leakage
  • Hissing around the cover
  • O-ring is flattened or permanently compressed
  • O-ring has cracked or hardened
  • Seal is torn, nicked, or cut
  • O-ring has swollen or distorted
  • Reservoir has been opened for separator or internal service

A physically damaged or previously compressed O-ring should generally be replaced rather than reused.

Is this an OEM part?

This is an OEM-equivalent replacement O-ring designed to meet the same performance standards as the original Quincy O-ring.  

How difficult is it to install?

Replacing the 123157-373 is generally a moderate to advanced compressor service task because accessing it requires opening the compressor’s pressurized air/oil reservoir. Because the seal is used on a pressurized separator/reservoir vessel, this service should be performed by someone familiar with rotary screw compressor reservoir maintenance.

Absolutely. We stock a range of air filters, oil filters, separators, synthetic oils, and many other maintenance parts for Quincy equipment. If you don’t see what you need, just ask and we’ll help you find it.

How do I know which oil to use in my Quincy compressor?

To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Quincy Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
