Flow-Control Mufflers

Adjust the flow by turning the screw. Use these mufflers with air-powered tools and cylinders to reduce noise and filter exhaust fumes.

For mufflers with an external hex drive, twist the screw and then tighten the hex nut with a wrench to secure. These mufflers are more secure than those with a thumb screw.

Stainless steel mufflers offer excellent corrosion resistance.
