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.

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.

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.

Nylon vents don’t conduct electricity, making them a good choice for most environments.

Polycarbonate vents don’t conduct electricity and withstand UV rays better than nylon vents, so they won’t break down as quickly in outdoor applications. All have a mounting nut for a secure connection in threaded as well as through holes.

Rated NEMA 4X, 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.

These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out. They have a PTFE seal that stands up to oil and corrosion and allows airflow in, reducing the risk of the seal failing due to changes in air pressure. They also minimize condensation that may rust internal electronic components. Made of polycarbonate, these vents withstand corrosion and UV rays.

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.

Glass-filled nylon drains are lightweight yet durable. They’re good for most areas.
