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 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.
