Maestrini reducing nipple adaptor made from brass. This nipple fitting connects two female threaded pipes of different sizes, a 1/4" BSP pipe to a 1/8" BSP pipe.

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.
