Breather Valves, also known as Pressure Relief Valves, protect sealed containers from excessive air pressure or vacuum buildup and protect contents from moisture, corrosion, sand, dust and insects. Breather Valves are easily installed and reduce container weight and volume.

Immersion Proof Breathers protect enclosures from excessive air pressure or vacuum buildup and keep water out when submerged in depths up to 30 feet for up to 24 hours.
