The Maestrini reducing bush adaptor is made from bronze. This material is tough and corrosion resistant making it suitable for exposure to sea water. This bush fitting adapts a 1/2" BSP Taper Male connection to a 3/8" BSP Parallel Female connection.

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