Prevost PPS Pneumatic Exhaust Silencers
Reduces noise at a compatible pneumatic exhaust port. Match the actual installation thread. BSPP and NPT thread options are distinct; these silencers are not pipe-to-pipe PPS connectors.
Choosing the Correct Model
Match the exact part number and connection arrangement. PPS pipe outside diameter, threaded port size and Compact Connection (CC) interface are different specifications. Photos may show several models; use the model table to identify what is supplied.

Frequently Asked Questions
Does a matching inch size guarantee compatibility?
No. Pipe sockets, CC interfaces, flange connections, NPT threads, BSPP threads and mounting threads serve different purposes. Use the exact model specifications.
