Description
The ST4 is a push-in silencer (muffler) that fits onto a tube line to quiet exhaust air, sized for a φ4 connection.
Drops the sharp hiss at a valve or cylinder exhaust port while keeping flow restriction low. Push it onto the exhaust port or tube by hand; the sintered element diffuses the escaping air so the exhaust pulse is quieter without choking the valve. Genuine PISCO ST Series.
Specify the ST4 by its exact model number. Sold individually.
