Compressed air exhaust can be loud, sharp, and constant—especially on high-cycle valves. The AirCraft SG PSU-15 Plastic Breather Silencer helps calm that noise by diffusing the outgoing air, making pneumatic systems noticeably quieter and more comfortable to work around.

With a 1/2" BSP male thread and a lightweight plastic body, it fits many common pneumatic exhaust and vent ports on valves, regulators, manifolds and air equipment where a breather/silencer is required. Simple part, big improvement: quieter venting, cleaner ports, and less workshop hiss.
