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.
Style S has a barbed fitting that slides into soft tubing, such as PVC, latex rubber, and silicone.
Style T has a push-to-connect fitting that connects to firm tubing, such as nylon, polyurethane, and FEP.
Brass, bronze, and copper mufflers offer good corrosion resistance.
Polypropylene and polyethylene mufflers offer good corrosion and abrasion resistance. Polyethylene also works well in oily conditions.
Polybutylene mufflers offer flame resistance. They’re good for use in welding applications and other areas where sparks may occur.

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 tube stem connections slide into tube fittings, such as push-to-connect tube fittings.

Exhaust Filters/Mufflers for Dry High-Vacuum Pumps
Purify exhaust fumes while silencing the noise from your oil-free high-vacuum pumps. With quick-clamp (KF) connections, these filters/mufflers connect to exhaust ports with a clamp and ring (sold separately). Mount them vertically or horizontally. All are carbon steel with a powder-coated finish for corrosion resistance.
