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.

Add a filling port to your hydraulic tank while protecting against excess pressure and vacuum. Breather vents stop debris from entering your tank. Mount them on top of standard tank openings with included hardware.

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.

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.

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.

These vents have louvers with foam filters to keep out dust and liquids. Use them to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.

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.
