OEM vs Aftermarket IR Parts – Which Should You Choose? 

One of the most common questions we hear is: 
"Do I need OEM Ingersoll Rand parts, or can I use aftermarket replacements?" 

The short answer: It depends on your application, budget, and system sensitivity. Both options can be effective if chosen wisely. 

What is an OEM Part? 

OEM (Original Equipment Manufacturer) parts are made by or for Ingersoll Rand and carry their brand name. These are exact-match components and are often required during the warranty period or for highly sensitive systems. 

Choose OEM when: 

• Your unit is still under warranty 
• You’re working in a tightly regulated environment 
• You need a guaranteed direct replacement and cost isn’t a major factor  

What Are Aftermarket IR-Compatible Parts? 

Aftermarket parts are made by third-party manufacturers and designed to match OEM specifications. High-quality aftermarket components offer the same fit and performance—often at a better price. 

Choose Aftermarket when: 

• Your unit is out of warranty 
• You perform frequent rebuilds or service large fleets 
• You want to reduce cost without sacrificing reliability 

Industrial Air Power’s IR-compatible aftermarket parts meet or exceed OEM specs and are rigorously tested for fitment and performance. In fact, our Ultimate 8000 Synthetic Compressor Oil is a direct alternative to IR’s SSR Ultra Coolant at a fraction of the price.
