Original Parts

All equipment parts begin as an Original Part. From the moment that a part is made, it is rigorously tested for quality and performance. After meeting the same testing standards as an OEM part, the Original Part is sold directly to a simple parts distributor, who then sells the part to a service technician ready to install it. Seems simple, right? It is.

Rest assured that Original Parts must pass all the same tests and standards as OEM parts before it leaves the factory, ensuring quality and performance. This way you’re only paying for the part, not the administrative overhead that a branded OEM part goes through.

OEM Parts

After testing at the manufacturing plant, OEM parts, on the other hand, are sent directly to an equipment manufacturer. The OEM part becomes branded with a specific brand at this point, which inevitably increases its base price. Once this process is complete, the part is sent to an authorized distributor that only sells parts of that particular brand. What does this additional middle man mean for you? An increase in price.

Aftermarket Parts

Aftermarket parts are classified as a secondary market of the industry. Because aftermarket parts are not concerned with the initial manufacturing of a part, but rather the remanufacturing, distribution and retail of a part (after the sale by an OEM), the same standards for performance and function are not as strictly enforced.
