Corrosion-Resistant Breather Vents
These breather vents withstand corrosion in damp environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
Stainless steel breather vents stand up to higher temperatures than polyethylene breather vents. Those with a Viton® fluoroelastomer O-ring offer extra protection against leaks. 316 stainless steel breather vents resist corrosion better than 303 and 304 stainless steel breather vents.

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.

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.
316 stainless steel breather vents have excellent corrosion resistance.

Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
304 stainless steel is more corrosion resistant than steel and aluminum.

Spark-Protection Chimney Vent Caps
The expanded mesh on these vent caps provides spark protection. They cover chimneys to reduce downdrafts and prevent obstructions from entering.
304 stainless steel caps are corrosion resistant.

High-Temperature Chimney Vents and Fittings
Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by gas, oil, wood, or coal.
To join pipes and connectors, twist a male end into a female end and secure with the included locking band.
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.

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.
316 stainless steel drains stand up to corrosion. They’re best for areas with salt water.
