About Noise, Filtration, and Flow Ratings

Mufflers
Use these mufflers with air-powered tools, valves, and cylinders to reduce noise and filter exhaust fumes.
Styles P, Q, and R have a tube stem that slides into tube fittings and collets to decrease noise from manifolds.
Polypropylene and polyethylene mufflers offer good corrosion and abrasion resistance. Polyethylene also works well in oily conditions.

High-Noise-Reducing Mufflers
Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30 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.

Clog-Indicating High-Noise-Reducing Mufflers
Don’t let an unexpected clog interrupt your work. These mufflers have a filter that slides up slowly as it clogs to indicate when the muffler should be replaced. Use on air-powered drills and other loud equipment to filter exhaust fumes and reduce noise by 30-35 dBA.
