If you work with pneumatic equipment, you know how loud those air exhausts can be - these IVLPHA air mufflers are about to become your new favorite workshop upgrade! These little guys screw right into your 1/8 inch male NPT ports and use sintered bronze material to quietly diffuse that noisy air exhaust. We're talking about reducing noise by at least 20 decibels, which is the difference between annoying loud hissing and a quiet whisper. Made from 100% brass with that sintered bronze filter, they can handle working pressures from 0 to 1.5 MPa and temperatures from -10 to 250°C (that's 14 to 482°F for us Americans). The flow rate is impressive too - 960 liters per minute means they won't restrict your equipment's performance while they're quieting things down. Perfect for air solenoid valves, cylinders, or any pneumatic tool that has that sharp exhaust noise that drives everyone crazy. The 5-pack is super handy because once you start using these, you'll want them on everything in your shop. Installation is simple - just screw them into any 1/8 inch male NPT port (make sure you've got the right thread type though - NPT, BSPT and BSPP aren't interchangeable). If you're tired of shouting over your air tools or just want a more pleasant workshop environment, these mufflers make a huge difference for such a small investment. Your ears (and anyone else within earshot) will thank you immediately!
