Midland Industries 300035 Pneumatic Muffler 1/2 in Mpt

Product Description

The MIDLAND INDUSTRIES 300035 is a stainless steel pneumatic exhaust muffler designed to reduce noise at air discharge points in compressed air and pneumatic systems. Built from 303 stainless steel with a 316 stainless steel sintered element, it handles operating pressures up to 300 psi and temperatures ranging from 35 to 392 degrees F. The 1/2-14 male pipe thread (MPT) connection allows straightforward installation into standard ported valves, cylinders, and fittings. Licensed HVAC technicians, plumbers, and pneumatic system technicians install this muffler as a direct thread-in component to control exhaust noise and back-pressure at valve outlets.

This muffler is suited for use in industrial and commercial pneumatic systems where stainless steel construction is required for corrosion resistance or sanitary considerations. Common applications include compressed air exhaust ports on directional control valves, solenoid valves, and pneumatic actuators. Its compact form factor makes it practical in tight panel or manifold installations. The stainless steel element provides filtration of exhaust air while simultaneously attenuating discharge noise.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation muffler for 1/2 in MPT-ported pneumatic valves, actuators, and cylinders in compressed air systems.

Installation Notes

Thread installation requires depressurizing the pneumatic circuit completely before removing or installing any exhaust muffler. Apply appropriate thread sealant compatible with compressed air service. Avoid over-tightening into aluminum or plastic valve bodies, as the stainless steel threads can cause damage. This fitting is typically installed by pneumatic system technicians or journeyman plumbers working within applicable compressed air piping standards.
