1/2" NPT Pneumatic Exhaust Muffler

1/2" MNPT exhaust muffler is perfect for reducing pneumatic noise levels in the work environment. Muffler - filters use a porous sintered bronze, bonded to a copper plated steel pipe threaded fitting. 40 micron filters diffuse air and muffle noise from exhaust ports of air tools, cylinders and valves to an acceptable OSHA noise requirement.
