About Noise, Filtration, and Flow Ratings

Use these mufflers with air-powered tools, valves, and cylinders to reduce noise and filter exhaust fumes.

Style B is knurled for easy gripping.

Styles G and H have a tube stem that slides into tube fittings and collets to decrease noise from manifolds.

Corrosion-Resistant Mufflers

Made entirely of stainless steel, these mufflers stand up to harsh, corrosive environments. Use them to reduce noise from equipment and to filter exhaust fumes.

316 stainless steel offers 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.
