At the proper density and firmness, felt can seal in lubricants or seal out contamination. It is one of the few materials, which will perform satisfactorily on a cost/effective basis for many packing applications.

    Recommended Uses

    Felt can be used for grease seals, dust shields, and gaskets on large doors and lids.

    Physical Properties

    Style 399 Meets the following:

    • SAE F-13ASTM: 9R4
    • Actual Wool Content (min.)
    • 75%Tensile Strength (min) 75%

    AP STYLE 403

    Style 403 is a woven thermoglass roving fabric in a plain weave colored with orange pigment. Applications include fire blankets, gasket cloth, welding and stress relief blankets, and drop cloths. Resistant to most chemicals and solvents, good flame protection to temperatures up to 1000º F.
