When your air compressor stops building pressure, one of the most common culprits is a faulty reed valve. This small but crucial part regulates airflow inside the pump head. Replacements are not always easy to find, and sometimes making your own reed valve is the fastest, most affordable solution.
In this guide, we’ll cover why reed valves fail, how to make your own, and which tools and materials you’ll need. We’ll also share some high-quality replacement kits for those who prefer a ready-to-install solution.

Buyer’s Guide: Reed Valves Explained
- What They Do: Reed valves control airflow by flexing open and shut with each piston stroke, allowing air in and preventing backflow.
- Why They Fail: Heat, wear, rust, and dirt cause valves to crack, warp, or lose spring tension.
- Symptoms of Failure: Compressor runs but doesn’t build pressure, overheats, or constantly cycles.
- Options: Buy OEM replacement kits or make your own using spring steel or feeler gauge stock.

FAQ
Can I really make my own reed valve?
Yes. Many DIYers successfully make reed valves using spring steel or feeler gauge stock cut to shape.
How long will a homemade reed valve last?
If cut and finished properly, homemade reeds can last months to years, though OEM parts generally last longer.
What thickness should I use?
Most reed valves are between 0.005” and 0.015” thick. Match your original valve thickness for best results.
What are signs my reed valve is failing?
Loss of pressure, constant running, overheating, and low CFM output usually indicate reed valve failure.
Is it better to buy or make a replacement?
If OEM parts are available, buy them. But if not, making your own is a proven and cost-effective fix.
Conclusion
A broken reed valve doesn’t mean the end of your compressor. With the right materials and a little patience, you can make your own and get your machine running again. For the most reliable repair, OEM kits from Ingersoll Rand, Campbell Hausfeld, or Quincy are excellent investments.
