Breather Vents
Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks. You can also use these breather vents to block debris from entering equipment.
Style H has a Buna-N O-ring for extra protection against leaks.

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.

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.
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.

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.
