    Stick these discs onto breather and other circular vents to guard against water and dirt without obstructing flow. Often used in the electronic and automotive industries, they have very small holes so air, gas, and vapor can still pass through. These discs are made of PTFE to wick water away. They also won’t break down from most chemicals, except alkali metal and high-temperature fluorinated agents.
    IP rated except for their adhesive, all seal out dust and stand up to some submersion.
    IP65 Enclosure Rating—IP65-rated discs also handle low-pressure washdowns.
    IP66 Enclosure Rating—IP66-rated discs withstand high-pressure washdowns.

    Stainless Steel Sintered Filter Discs

    Image of Product. Front orientation. Sintered Filters. Stainless Steel Sintered Filter Discs.
    Also known as frits, these discs have tiny holes that trap very small particles. Discs are often used in laboratories and gas-bubbling applications (sparging). They’re made of 316L stainless steel for excellent corrosion and abrasion resistance.
    Select discs based on the size of the particles you wish to remove. For example, the particle size of talcum is about 10 microns.
