The SEAFLO Thru-Hull Fitting is designed for overflow, bilge, and discharge use through the transom. Made from durable, UV-resistant marine-grade polypropylene, this is a marine-grade connector designed for tough conditions and high-flow reliability. Ideal for bilge discharge, livewell overflow, or sink drains, this fitting installs through the transom and creates a tight, leak-free seal. Built to perform in saltwater environments, it's the trusted choice for marine professionals and boat owners alike. Its wide flange provides a secure seal, and molded threads ensure a snug, watertight fit during easy installation.
