【High Quality Material】: Drain plug is made of high-quality PA plastic, which is durable, not easy to age, wear-resistant, corrosion-resistant, resilient, and has high compressive strength. The plug and barb are not easy to break. When you unscrew the drain plug, the fixed hook of the drain plug will stay in the ship to prevent it from falling and losing during disassembly.
【Good Sealing Effect】: The O-ring of the drain plug is made of Nitrile rubber, which has good sealing performance. It can seal the gap between the drain plug and the hull.
