Industrial D5500A5013 Pneumatic Silencer Three Quarter Port

Ross Controls 5500A5013 (D5500A5013) Pneumatic Silencer is a 3/4-inch NPT male-thread exhaust muffler designed for standard 3/4" port exhaust outlets on valves, cylinders, and other pneumatic components. It reduces noise from compressed-air exhaust while maintaining exhaust flow, making it suitable for automation lines, workshops, and lab environments where quieter operation is desired. The silencer is rated for a maximum operating pressure of 150 psi (0–10.3 bar) and weighs approximately 0.2 lb (0.1 kg). This model is listed in Ross catalogs as 5500A5013 and its D5500A5013 variant, confirming its 3/4" port size and male-thread configuration. Typical applications include exhaust termination on pneumatic valves, actuators, and manifolds in industrial automation settings where standard 3/4" ports are used. The Ross silencer line, including the 5500A5013/D5500A5013, is widely referenced in distributor catalogs and official product documents, reinforcing its role as a straightforward, compatible solution for quieting 3/4" exhausts in mixed pneumatic systems. D5500A5013 is the D-prefix variant noted in Ross documentation to indicate alternate threading variants as applicable; these silencers are commonly listed by distributors such as Radwell and IMS Supply, reflecting broad availability for 3/4" exhaust needs.
