Parts are parts, right? Not exactly. Your air compressor is a vital part of your operation and you want to take care of it, keep it running efficiently and economically and ensure it stays that way for a long time. You wouldn’t put generic oil and parts in your car and trust them to last. Why would you treat your compressed air system any different?


There are things you need to know about aftermarket parts vs. Original Equipment Manufacturer parts.

OEM (Original Equipment Manufacturing) parts are critical to the life of your compressor. The peace of mind that you’re using genuine parts that are specifically designed and meet the specs of the manufacturer is second to none. You can also rest easily knowing that you’re using parts that meet warranty requirements and provide for extended warranty advantages. The downside is that OEM parts have the reputation of being more expensive. There is also a perception that OEM parts are hard to find with local parts dealers sometimes only carrying aftermarket brands versus the factory direct OEM parts. Given this information it’s often asked why someone would choose to use OEM parts to service their air compressor.



OEM parts can carry a higher cost; however, they are engineered to be an exact replacement for the original component. This can make sure you get the most out of your air compressor.

In many cases we cannot afford for our compressors to be “down” or not functioning properly. Utilizing OEM parts can help ensure you are servicing your air compressor with the manufacturers’ suggested replacement components.



OEM parts are usually a requirement to receive coverage from the manufacturers warranty plan. In many cases utilizing OEM parts can offer an option for extended coverage. This can prolong the life of air compressor and give you confidence that the compressor is covered.

Don’t be caught off guard when the unexpected occurs and your warranty coverage is invalid due to saving a few cents on a part or lubricant.


OEM parts work exactly as the one you are replacing. They are the same components the air compressor were manufactured with and gives you a taste of familiarity and performance.

Other brands of aftermarket parts may not work correctly or be of lesser quality. OEM parts are tested with the machines and matched to specifications of the original machine design.
