Flow-Control Mufflers
Adjust the flow by turning the screw. Use these mufflers with air-powered tools and cylinders to reduce noise and filter exhaust fumes.
For mufflers with an external hex drive, twist the screw and then tighten the hex nut with a wrench to secure. These mufflers are more secure than those with a thumb screw.
For mufflers with a thumb screw, twist the screw and friction secures them in place—no need to use a wrench. Often used in valve exhaust ports, these mufflers are not as secure as those with a nut.
Brass, bronze, and nylon mufflers offer good corrosion resistance.
Stainless steel mufflers offer excellent corrosion resistance.

High-Noise-Reducing Mufflers
Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30-35 dB, a reduction that's equivalent to putting in earplugs.
Mufflers with pipe connections thread into NPT or metric threaded exhaust ports.
Mufflers with tube stem connections slide into tube fittings, such as push-to-connect tube fittings.
