Wherever a pressurised hydraulic system is to found bonded seals provide a convenient sealing method between hoses and components, and similar sealing needs. The metal ring, to which is bonded a trapezoidal rubber ring, ensures the joint can be correctly torqued without damage to the sealing element. The seals are available in both metric and imperial sizes and some special designs also exist. Materials available are steel, stainless steel, brass or aluminium for the metal washer, Nitrile, Viton, Silicone, EPDM or HNBR for the sealing element. Care should be taken to ensure the burst pressure of the chosen seal is rated within tolerance of quoted maximum pressures.
