Maestrini equal nipple connector 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 4" BSP hex nipple is used to connect two pieces of equal sized 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.
