    Fuel Caps

    with Vent

    Often used with trailers, compressors, and other equipment tanks, these caps meet Department of Transportation requirements. Caps have fusible plugs that will melt when the outside environment reaches their opening temperature.
    Fuel Caps with Vent—Cap with vent will automatically open when the internal pressure reaches between 6.5 psi to 8.5 psi to relieve pressure.

    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.

    Exhaust Vent

    Cover vents with caps that let air in or out.
    Exhaust Vent—A built-in damper allows air to escape while blocking backdrafts, rain, and snow.
    Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

    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.

    EMI/RFI Shielding Electrical Enclosure Vents

    Image of Product. Front orientation. Electrical Enclosure Vents. EMI/RFI Shielding Electrical Enclosure Vents.
    These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.
    Screw through the vent frame to mount on the surface of your enclosure. A shielded foam gasket fills the gap between the enclosure and the vent.
    Interference Reduction @ Frequency—Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.
