Bonded seals (Dowty-type washers) combine a metal washer with a rubber sealing ring for reliable, one-piece sealing under bolt heads and fittings.
Bonded seals combine a metal washer with a vulcanized rubber sealing ring in a single component, providing reliable sealing under bolt heads, banjo fittings, and threaded connections without the risk of a separate O-ring extruding or dislodging during assembly. We supply bonded seals in a full range of standard metric and imperial sizes, with NBR, FKM, or EPDM sealing elements bonded to steel, stainless steel, or aluminum washers.
