Brass Silencer, Easy Installation, Quick & Reliable Connection

Various types of brass silencers on the white background.

Brass silencers are typically installed on exhaust or vent ports.

Brass Silencer, also known as brass muffler, is made of sintered brass powders and a brass housing. Typically, it is widely used to reduce dynamic noise of the pneumatic components or device exhaust to an industry accepted level with minimum flow restriction and prevent metal chips, abrasive grits, dust and other contaminants from entering open exhaust ports. Brass silencer can also be used for air cylinders, solenoid valves, pneumatic valves, air tools, etc.
