Blakes 1 1/2" Seacock Handle for Blakes Seacocks. The body and plug are made of DZR1 (BSEN 1982 CC752C). A dezincification resistant brass for die casting. If zinc is leached from brass by sea water corrosion, the brass will become porous and fail. DZR1 resists the zinc removal and is approved by Lloyds if used in a marine environment. The seacock bolts are manufactured from Phosphor bronze.
