Fittings, Filters & Mufflers

Brand: Dwyer Instruments, LLC

A wide variety of fittings for use with most Dwyer products.

Special line filters for the Magnehelic® Gauge and Capsuhelic Gauge allow use with dusty environments. Particulate filters are used for Dwyer Flowmeters to keep the air clean. 

The Muffler Accessory can be easily field installed to any diaphragm valve with an exhaust. Pneumatic exhaust ports are on the diaphragm valves that have dual diaphragms and the units with the integral mounted solenoid.

The muffler decreases the amount of noise when the air is exhausted from the valve. 

Valves with dual diaphragms and an integral solenoid have two exhaust ports and will require one A-237 and one A-238.
