Bungs

Our Bungs range covers drain plugs and bungs for transom drains, self-bailers and deck fittings – small parts that are easy to overlook but that stop a boat filling with water through an open drain.

A missing or perished transom bung is a surprisingly common and entirely avoidable cause of a swamped dinghy or RIB, so it’s worth keeping spares aboard rather than relying on a single bung that could be lost or split. Check the bung’s size and thread or push-fit type matches your specific transom or self-bailer fitting before ordering, since these vary between manufacturers. Rubber and plastic bungs perish and crack with UV and age even when not in regular use, so it’s worth checking spares in your kit occasionally rather than assuming they’re still good.

Frequently asked questions

Why do boats have bungs?

They plug transom drains and self-bailers – removed to drain water on the trailer or slipway, but must be fitted before launching or the boat can swamp.

How often should I check spare bungs in my kit?

Occasionally – rubber and plastic bungs perish and crack with UV and age even sitting unused in a kit bag.
