Hazardous Location Threaded Breather Vents
Safe for use around flammable and combustible gases, vapors, fibers, and dust, these vents allow air to flow through enclosures to maintain consistent pressure and reduce moisture buildup as temperatures change. They also stand up to washdowns. Made from 303 stainless steel, these vents will not corrode from salt water and chemicals.

Submersible Threaded Breather Vents
Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures. All have a hydrophobic and oleophobic filter membrane that blocks moisture and contamination from particle buildup.
Nylon vents don’t conduct electricity, making them a good choice for most environments.
Polycarbonate vents don’t conduct electricity and withstand UV rays better than nylon vents, so they won’t break down as quickly in outdoor applications. All have a mounting nut for a secure connection in threaded as well as through holes.
Nickel-plated brass vents stand up to corrosive environments better than nylon and polycarbonate vents. They’re also durable, which means you won’t have to replace them as often.

Corrosion-Resistant Washdown Threaded Breather Vents
Rated NEMA 4X, these vents provide protection from washdowns, corrosion, and power jets of water. Use them to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.
For technical drawings and 3-D models, click on a part number.
Submersible Snap-In Breather Vents
No threaded hole or tools needed—snap these vents into enclosures with a maximum 1/8” panel thickness to let airflow in and keep water out even when submerged. Use them to maintain consistent pressure inside your enclosure as temperatures change. These vents have a pressure compensating seal that prevents pressure buildup. They also have an acrylic filter that resists dust, water, and oil.

Wet Location Breather Vents
These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out. They have a PTFE seal that stands up to oil and corrosion and allows airflow in, reducing the risk of the seal failing due to changes in air pressure. They also minimize condensation that may rust internal electronic components. Made of polycarbonate, these vents withstand corrosion and UV rays.

Enclosure Vents
Attach these vents to the top or side of sealed enclosures, so air can flow through to equalize internal and external temperature and pressure.
Style A and B vents have an angled outlet, which helps keep rain, snow, and debris from entering the vent and the enclosure.
Style C vents have mounting holes for attaching a fan (not included), so you can increase the amount of air that flows through your enclosure.
Style D vents are protected from rain and water, so you can use them in washdown and other wet environments.

EMI/RFI-Shielding Enclosure Vents
These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.
Screw through the vent frame to mount on the surface of your enclosure. A shielded foam gasket fills the gap between the enclosure and the vent.
Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.

Vented Brass Submersible Cord Grips
Secure cable installed through enclosures in wet environments while venting air to protect electronics from condensation. Vents on these cord grips equalize pressure between the inside and outside of an enclosure, preventing harmful moisture from forming. They are nickel-plated brass, so they resist corrosion. These cord grips are rated IP66 and IP67 for protection from dust, washdown, and temporary submersion.
