Milton 1086‑8 ½″ NPT Exhaust Muffler

Milton 1086‑8 ½″ NPT Exhaust Muffler is a compact pneumatic silencer engineered to drastically reduce exhaust noise from tools, valves, and cylinders. The Milton 1086‑8 ½″ NPT Exhaust Muffler features a sintered bronze element pressed into a copper‑plated steel housing with a ½″ MNPT thread—perfect for compressor outlets, air tools, and valve ports.

Engineered to comply with OSHA noise requirements, this muffler uses a 40‑micron filtration grade bronze medium to diffuse exhaust airflow effectively. Tested for maximum airflow of 20 SCFM at 100 psi, the Milton 1086‑8 ½″ NPT Exhaust Muffler operates quietly while maintaining airflow efficiency.

Manufactured to Milton’s industrial standards, the muffler supports pressures up to 300 psi and temperatures ranging from 40 °F to 300 °F. The 7/8″ hex base allows quick wrench installation, while the compact 1.88″ length and 0.88″ diameter make it ideal for tight spaces. Assembled in the USA, it offers reliable, corrosion‑resistant performance for shop and field use.

The Milton 1086‑8 ½″ NPT Exhaust Muffler is easy to install: simply thread into any ½″ male NPT exhaust port with a wrench, no additional tools or components required. The bronze filter element also absorbs exhaust moisture and oil mist, protecting the work environment from contaminants.
