The Osculati reducing bush fitting is made from stainless steel 316. This material is the marine grade stainless steel making it suitable for exposure to sea water. This reducing bush adapts a 1/2" BSP male connection to a 3/8" BSP female connection.

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