Description

Product Identity: A reliable marine-grade hardware accessory designed to keep your watercraft secure and dry during every water adventure.

Primary Function: This purpose-built drain plug effectively seals the hull drain opening to prevent water intrusion and opens easily for quick drainage.

Secure Design: Featuring a durable boat drain plug with flange, this assembly includes an oval mounting flange with two pre-drilled screw holes for a stable, permanent installation.

Self-Retaining Feature: Engineered as a threaded drain plug with screws, it comes with a tethered pull tab that keeps the plug body attached to the flange even when unscrewed, preventing accidental loss.

Versatile Application: This long-lasting black PP plastic boat drain plug is the perfect replacement part for maintaining a dry, leak-leakproof hull on kayaks, canoes, and small boat transoms.

Common Questions

What drain hole size does this plug fit?
The exact drain hole size is not specified. The product is a threaded plug with a mounting flange, intended for kayaks, canoes, and small boat transoms. Package dimensions are 19 × 16 × 4 cm, but plug dimensions are not listed. Check your existing drain hole and compare before ordering.
What material is the plug made of and does it rust?
The plug body is black PP (polypropylene) plastic, and the hardware is described as marine-grade. PP plastic does not rust, and the tether and flange are designed for water exposure. Rinsing with fresh water after saltwater use will help maintain it.
Does it come with mounting screws?
The product title says 'with Screws', but the description only mentions an oval mounting flange with two pre-drilled screw holes. Screws and their size are not explicitly listed in the description, so confirm contents before ordering if you need them included.
Is this plug compatible with inflatable boats?
No. The product is listed as not for inflatable boats because they are non-compatible with a rigid flange. It is intended for rigid hulls such as kayaks, canoes, and small boat transoms. For a tool-free inflatable plug, this is not suitable.
How long will shipping take?
This item ships from China. Typical delivery is 7–30 days depending on the shipping tier selected. Note that checkout requires human approval, which may add a small delay before the order is processed.
