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.
Breather vents with splash guard are good for containers that are often filled and drained; they have a guard that prevents oil from splashing out of the vent hole.
Style G has a slotted drive for installation with a screwdriver.
Style H has a Buna-N O-ring for extra protection against leaks.

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.
Vents with barbed connections fit unthreaded openings and are held in place by friction.

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.
Polyethylene breather vents can be cleaned with mineral spirits.
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.

Moisture-Eliminating Breather Vents
Keep moisture, dirt, and debris from entering your oil reservoirs. The silica gel inside these breather vents absorbs moisture from the air, preventing rust from forming inside your tanks. The gel changes from blue to pink as it becomes saturated, letting you know it needs to be replaced. A second filter blocks dust and other particles from getting inside. These breather vents allow air to flow in and out of your lubrication system, keeping excess vacuum or pressure from building up in cylinders, gear boxes, and tanks.
Breather vents with a plastic body are clear, so a quick glance will tell you if the gel is saturated. Unlike steel versions, which can be rebuilt, the entire unit must be replaced when fresh gel is needed. For washdown environments, select breather vents with check valves. These valves allow air to flow in and out, but close when liquids try to enter.
For an extended service life, use breather vents with a steel body. They are stronger than breather vents with plastic bodies and hold up better when exposed to chemicals. A window lets you check the color of the gel. No need to replace the entire unit when the gel is saturated—use rebuild kits to add fresh gel and to replace the window, filters, and gaskets.

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.

Often used with trailers, compressors, and other equipment tanks, these caps meet Department of Transportation requirements. Caps have fusible plugs that will melt when the outside environment reaches their opening temperature.
Cap with vent will automatically open when the internal pressure reaches between 6.5 psi to 8.5 psi to relieve pressure.
