The 770075 RFI/EMI Shielded Nut Assembly is intended to provide RFI/EMI shielding on the inside of the housing.  Air which passes through the valve also passes through a 60 by 60 mesh Type 304 stainless steel cloth.  This cloth, when joined to the MIL-DTL-5541, Type 1, Class 3 conversion coated aluminum body with silver-filled conductive epoxy, forms a Faraday cage which protects the interior of the container from unwanted radio frequency and electromagnetic radiation.

The 770075 comes standard with a silicone base conductive gasket*.

In order to make the conductive path complete, the interior surface of the case, which the conductive gasket touches, must also be conductive. Four grooves in the wall of the nut provide a convenient gripping point for a hook spanner wrench for tightening.

Custom RFI/EMI Shielded Nut Assemblies are also available for: TA292 Breather Valves, TA294 Breather Valves, TA330 Breather Valves, TA333 Breather Valves and higher attenuation requirements using honeycombed aluminum or drilled holes.

*Conductive gasket utilizing other base materials are available upon request.
