Enclosure Drains
Mount these drains at the bottom of your enclosure to let moisture drip out and keep electronics dry.
Style A drains have a gasket that seals out air, water, and dust during high-pressure washdowns or when submerged. They also meet UL 94 V-0 for flame retardance.
Style B drains are for use in dusty and wet environments.

Hazardous Location Enclosure Drains
Safe for use around flammable and combustible gases, vapors, fibers, and dust, these drains let moisture buildup from temperature changes inside enclosures drip out to keep electronics dry. Mount them at the bottom of enclosures.
1/2 pipe-size drains also stand up to washdowns and weather.

Hazardous Location Drain Vents
Safe for use around hazardous gasses and dust, these vents maintain steady pressure and prevent moisture buildup from temperature changes inside enclosures. They allow air to flow through the enclosures while protecting the contents from washdowns, dirt, and weather. Install these vents at the lowest point on an enclosure, so moisture can drip out.
Increased-safety drains keep sparks, high temperatures, or current creepage inside an enclosure, so they won’t ignite flammable gasses and dust.
Flameproof drains reduce the risk of igniting flammable gasses and dust if an explosion occurs within the enclosure.
Glass-filled nylon drains are lightweight yet durable. They’re good for most areas.
316 stainless steel drains stand up to corrosion. They’re best for areas with salt water.

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.

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.

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.

Self-Draining Breather Vents
Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
Brass breather vents have good corrosion resistance.
316 stainless steel breather vents have excellent corrosion resistance.
