    Style H—Style H has a Buna-N O-ring for extra protection against leaks.
    Splash Guard—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.

    Moisture Absorbing 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.
    Nylon and Polycarbonate Body—NPT Male
    Image of Product. Front orientation. Breather Vents. Moisture Absorbing Breather Vents, Nylon and Polycarbonate Body—NPT Male.
    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.

    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.

    Repair Kits

    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.
    Repair Kits—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.

    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.

    Lockable Breather Vents with Cap

    Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering. These breather vents allow you to add a filling port to your hydraulic tank while protecting against excess pressure and vacuum. Use them to stop debris from entering your tank. Breather vents mount on top of standard tank openings with included hardware. Padlock is not included.

    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.
