Noisy exhaust ports make a machine unpleasant to work beside. The ASCO M3MB is a Series 346 threaded pneumatic silencer with a G 3/8 male connection, in zinc-plated steel, rated to 14 bar.
Screwed directly into an exhaust port, it diffuses the escaping air through its element, reducing noise while keeping the exhaust free-flowing. It is supplied as genuine ASCO stock, so it matches the original design and specification exactly.
Typical uses include valve manifolds and exhaust ports on noisy machines, workplaces reducing operator noise exposure, and routine replacement of clogged silencers. Exhaust noise is one of the biggest contributors to noise on a pneumatic machine. Every time a valve switches, a burst of air leaves the exhaust port, and across a whole machine that adds up to a harsh, fatiguing environment for operators. A threaded silencer on each exhaust port is a simple, low-cost fix.
When choosing, match the thread size to the exhaust port and choose a silencer whose flow capacity will not restrict the exhaust, as a restricted exhaust slows actuator motion. Check and replace silencers during routine maintenance, because a clogged element raises back-pressure.

Frequently Asked Questions
What does the ASCO M3MB do?
It reduces the noise of air leaving a valve or cylinder exhaust port.
What thread does it have?
A G 3/8 male thread.
What is it made of?
Zinc-plated steel, rated to 14 bar.
Will a silencer slow my cylinder down?
A correctly sized silencer has little effect. An undersized or clogged silencer can restrict exhaust flow and slow the actuator, so match it to the port and replace it when dirty.
Can you supply matching ASCO parts in the same order?
Yes. General Tech Services LLC supplies ASCO solenoid and spool valves, shut-off valves, silencers, filters, regulators, cylinders and position detectors. Share your requirements and the team can quote matching parts together.
Should I choose this model or the ASCO M2MB?
The M2MB differs by having a G 1/4 thread, while the M3MB has a G 3/8 male thread. Match the size, function and application to your machine first. The team can compare both options based on your requirements.
What details should I send with a quote request?
Share the part or model number, quantity and application details, such as size, pressure, flow and environment. This helps confirm the exact ASCO variant and provide an accurate price and lead time.
Is genuine ASCO stock available in the UAE?
Yes. Genuine ASCO stock is available for supply across the UAE. Contact General Tech Services LLC for current pricing and lead time.
