The Maestrini reducing nipple adaptor is made from bronze and features 3/4" BSP Tapered male and 1/2" BSP Tapered male threaded connections. This material is tough and corrosion resistant making it suitable for exposure to sea water. This nipple fitting connects two female threaded pipes of different sizes.

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.
