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.
Styles D and E have a rubber O-ring for extra protection against leaks.
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.

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.
For mufflers with a thumb screw, twist the screw and friction secures them in place—no need to use a wrench. Often used in valve exhaust ports, these mufflers are not as secure as those with a nut.
Brass, bronze, and nylon mufflers offer good corrosion resistance.
