URBEST 10Pcs Solenoid Valve Pneumatic Muffler Filter Noise Silencer 1/4" PT Thread Pneumatic Air Cylinder Accessories

There is a lot of compressed air-powered equipment where I work. Lots. LOTSSSSSSbr>br>It sounds exactly like one of these to the untrained ear. In reality, it's probably about a third of the volume, with the same hissss. To those who are familiar with dB, this means you're reducing the volume by four decibels. 5 dB, which is 100% worth it and about as good as cheap earplugs. Most stationary equipment has 1/4" npt exhaust as well. br>br>I didn't use thread tape because I figured it was supposed to leak, but the spongey part seems to let the most air out; if you're worried about performance loss, you can blow through them with your mouth ( Water and oil contaminants will easily pass through. br>br>Also, as I previously stated, it appears to be a strange clay sponge in the photo, but it is unmistakably brass. br>br>It would be fantastic if someone could find those nice muffle filters (often seen on vacuum pumps) for under $5 each. In the meantime, these are fantastic for less than $1 each!.
