    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.
    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.

    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.
