Use these mufflers with air-powered tools, valves, and cylinders to reduce noise and filter exhaust fumes.
Styles C, K, and M have a slotted drive for installation with a screwdriver.
Brass, bronze, and copper mufflers offer good corrosion resistance.
Nylon mufflers resist corrosion and will not deteriorate when exposed to oil.
Acetal mufflers won't absorb water or lose strength, even in high-humidity environments.
Polypropylene and polyethylene mufflers offer good corrosion and abrasion resistance. Polyethylene also works well in oily conditions.

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.
Brass, bronze, and nylon mufflers offer good corrosion resistance.
