Mufflers with Tube Connection


Style R	Style S	Style T

Style R—Styles P, Q, and R have a tube stem that slides into tube fittings and collets to decrease noise from manifolds.

Style S—Style S have a barbed fitting that slides into soft tubing, such as PVC, latex rubber, and silicone.

Style T—Style T have a push-to-connect fitting that connects to firm tubing, such as nylon, polyurethane, and FEP.

Bronze Body—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.

Mufflers with External Hex Drive

NPT Brass

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.

Right-Angle-Shaft Air-Powered Gearmotors

Use these right-angle gearmotors where space is at a premium. They transmit motion at a 90° angle from the motor, so they’re positioned alongside your application when mounted. A motor and speed reducer in one, gearmotors slow speed while increasing torque. They come with a muffler to reduce noise and filter exhaust air.

Air-Powered Gearmotors

With a motor and speed reducer in one, you can use these gearmotors in air-powered applications to slow speed and increase torque. They come with a muffler to reduce noise and filter exhaust air. Gearmotors transmit motion inline with the motor. Set for clockwise or counterclockwise rotation.
