The Maestrini reducing bush adaptor has a brass construction. This bush fitting adapts a 1-1/2" BSP Tapered Male connection to a 3/4" BSP Female Parallel connection.

Please Note: All fittings used for through hull applications must be correctly electrically bonded to ensure protection from electrolytic corrosion. Brass is susceptible to dezincification and is not recommended for below waterline through hull applications.
