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.

Shield outdoor pipe and tank openings from the environment. Also known as vent caps, these breather vents have screens to allow air flow while blocking debris. Use them to prevent excess vacuum and pressure in your equipment.

Style C has a set screw to secure in place

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.

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.

Zinc and zinc-plated steel fittings have mild corrosion resistance. Nickel-plated brass fittings are more corrosion resistant than zinc-plated brass fittings.

Fittings with a self-closing hinged cover block contaminants from entering equipment.

UNF and UNEF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.

Note: Fittings do not hold oil; any oil dispensed into the fittings passes into the part to be lubricated.
