There may be a brass version made heavier for use at higher pressure, or perhaps one made of stainless steel instead of brass. I am using it at very low pressure in a computer water cooling loop to adapt thread sizes where a smaller and lighter fitting was preferable for me. I would search for a fitting that states it is good for a 3100psi working pressure or higher, or you are taking a risk of serious injury should this fitting burst. **Q: Which size fits a Schrader valve?** A: A Shrader valve is: 0.305" in OD, thread root diameter 0.302" in x 32 tpi (threads per inch). A Shrader valve is not a NPT thread. Try B09QMCF6BK. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sturdy and good Fitting *by K***R on November 10, 2025* Good quality, great for repairing my air compressor. ### ⭐⭐⭐⭐⭐ Good quality *by S***M on May 31, 2023* I got these to reduce an air line from 1/4" to 1/8".
