Seabung's revolutionary design allows the replacement of ball valves attached directly to thru-hull fittings secured by a lock nut while your boat is in the water. This allows you to perform emergency maintenance on water inlets and outlets in between scheduled haul-outs.
Should there be a catastropic thru-hull failure - due to structural failure from corrosion, or as the result of a collision - the Seabung can be used to quickly plug an intact (undamaged) thru-hull hole as a temporary emergency measure.
If one were at sea at the time, prudence dictates replacing the Seabung with a wooden plug, which will swell and “lock” in place, as soon as possible.
Seabung is made of a flexible, elastomeric polyurethane outer with a stiff, tough ABS core.
It is supplied as a pack of 2 sizes of bungs for thru-hulls holes sized 3/4" - 1-1/4" (19mm-32mm), and for larger thru-hulls from 1" - 2" (25mm-63mm).

* A few words of caution and common sense when using the Seabung.
• If the seacock is secured to its backing plate with screws, it may be rotated off the thru-hull without breaking the bedding seal under the head of the thru-hull. However, if the seacock requires significant torque to be removed, before removing the seacock, it may be necessary to first secure the connected thru-hull from outside the hull to avoid damaging the bedding seal between the thru-hull and the hull.
• If the seacock is secured to its backing plate by sliding onto bolts embedded in the backing plate, then the only way to remove it is to unscrew the thru-hull from outside the hull.
• You should continue to carry wood plugs in your boat – the Seabung is not meant to replace these important safety devices.
