AirCraft Plastic Breather Silencer 3/4" BSP Male Blue (SG PSU-20)

At a Glance: 3/4" BSP male plastic breather silencer—reduces pneumatic exhaust noise and helps keep venting cleaner.

Big ports move a lot of air—and when that air vents, it can get properly loud. The AirCraft SG PSU-20 Plastic Breather Silencer helps soften pneumatic exhaust noise by diffusing the outgoing air, making high-flow valve and manifold exhaust noticeably quieter and more workshop-friendly.
With a 3/4" BSP male thread and a lightweight plastic body, it suits many pneumatic exhaust and vent points on valves, manifolds, regulators and air equipment where a breather/silencer is required.
It’s a simple part that does an underrated job: reduce noise, keep venting cleaner, and make the whole system feel more civilised.
