FKM Self Centering Zinc Bonded Sealing Washer M18

FKM Bonded Seal Washers: These washers are used to seal bolt heads and prevent leakage from hydraulic fittings, pipe joints and valve bodies. A bonded washer consists of a metal washer bonded to a rubber internal diameter that is wider than the washer. As the bolt is tightened, the rubber seal element is compressed until the bolt head contacts with the metal outer of the washer, creating an efficient high-pressure seal. The inside material is made from FKM (Fluoroelastomer).
Note: These washers are designed to fit in conjunction with BSP (British Standard Pipe) the actual size of the inside diameter will not be the BSP size - Please refer to the technical tab for the actual sizes and a conversion table for BSP to mm/inch
