AG running nipple fitting made from dezincification resistant brass (DZR), also known as CR brass which stands for corrosion resistant. This material is a brass alloy which prevents corrosion, caused by the loss of zinc in the fitting, making it suitable for exposure to sea water. This 1-1/4" BSP running nipple connects two pieces of equal threaded pipe.

Please Note: All fittings used for through hull applications must be correctly electrically bonded to ensure protection from electrolytic corrosion. DZR is suitable for below waterline through hull applications.
