The Circle Seals are circular brush seals with a single brush spiral, which provides an intrinsically more efficient seal thanks to the geometry of the brush filaments.
4" Circular Surface Mount Brush Seal
The Circle Seals can be fitted straight over the cut-out using the supplied self-drilling screws. The multipiece frame design of the Split Ring Circle Seal allows the spiral brush to be removed and wrapped around the cable, and the housing will then snap around the brush. Using XtraSeal technology, the Surface Mount Brush Seal incorporates a thin flexible membrane (EPDM) to provide an almost impenetrable air barrier.
