Just drill a 1” hole, test fit drain tube, and cut it to size using the lip of the swage as a guide. Slather the drain tube and opening with 3M 5200 and use an 18mm wrench and large ratchet to flare it in. This tool works perfectly. 100% satisfied!
Needed this tool when replacing the stern drain sleeve..worked effortlessly and made the finish job neat and complete.
Worked perfectly flaring the sea sense brass drain tube. Just use it like any other flaring tool and use the flaring dimple as a gauge of how much excess to cut off. The picture attached is the end that was only flared using this tool, not the pre-flared end of the sea sense drain tube.
Great quality, easy to use! One of those tools that you need and nothing else will work.
This product makes installing a new drain tube in a boat easier.
