Washdown Weather-Resistant Breather Vents
These breather vents are rated NEMA 6 to withstand periodic submersion in water. Install them in enclosures to stop the buildup of pressure and vacuum and to prevent debris from entering equipment. Breather vents can be used with enclosures that are rated NEMA 4, 12, and 13 for washdown environments and splashing oil and coolant.

High-Noise-Reducing Mufflers
Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30-35 dB, a reduction that's equivalent to putting in earplugs.
Mufflers with pipe connections thread into NPT or metric threaded exhaust ports.

Submersible Threaded Breather Vents
For the highest level of protection from water, these vents are rated IP68 for protection from water submersion. Use them to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.
Corrosion-Resistant Washdown Threaded Breather Vents
Rated NEMA 4X and IP66, 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.

Enclosure Drains
Mount these drains at the bottom of your enclosure to let moisture drip out and keep electronics dry. Rated IP66, IP67, and IP69K, they have a gasket that seals out air, water, and dust during high-pressure washdowns or when submerged in up to 1 meter of water for 30 minutes. Drains meet UL 94 V-0 for flame retardance.
