Breather Valves, also known as Pressure Relief Valves, prevent excessive
pressure or vacuum buildup in sealed containers, which reduces container weight,
cube, and cost. AGM manufactures a variety of Breather Valves, which include valves that keep dust, water, and
blowing sand from entering containers. These Breather Valves meet SAE AS27166 (replaces cancelled MIL-V-27166) and MIL-DTL-27166 which is the re-instated version of MIL-V-27166.. Products include: One-Way Pressure Relief Valves; Two-Way Pressure Relief Valves; Breathing Desiccators; Filler Valves; RFI/EMI Shielded Nut Assemblies; Drain Plugs; and Mounting Flanges. AGM also offers a full line of Immersion Proof Breathers.
Please Note: Unless otherwise specified in AGM's catalog, all valves are supplied
with a nut, washer and gasket for mounting through a hole on a
flat, smooth surface. Valve gaskets may not provide a proper seal
if the mounting surface is curved or rough. Valves can also be
installed in a mounting flange or a threaded boss when a suitable
counterbore has been provided for thread relief.
