This porous metal muffler includes a manually-adjustable, tapered metering valve to provide needle-point control of air flow on pressure (exhaust) applications as well as for vacuum relief on vacuum systems
Air flow is metered between fully closed and fully open using an external adjustment screw
Locknut allows desired setting to be locked in to prevent accidental changes
