This one-way flapper maintains a tight seal with minimal pressure to effectively guard against backflow while ensuring efficient deck drainage in harsh saltwater environments. The added weight of the stainless steel design helps prevent the flap from opening with every motion of the transom, offering superior durability and sealing performance compared to standard plastic alternatives.
