TruPlug is a temporary or emergency plug for your boat.


TruPlug is a temporary or emergency plug for your boat where water would enter a circular, oval, or irregular hole caused by maintenance failure or hull breach due to impact. A 2 hole in your boat, only 1 foot below the waterline would fill a 55 gallon drum in 40 seconds. Bilge pumps can not keep up. You must stop the water. TruPlug is a tapered circular cone shaped plug made of a proprietary foam formulation that is a solid, spongy and coated with a flexible sealer 9″ (23 cm) high, 4.75″ (12 cm) diameter at base. Weight: 3.9 oz (110g).

TruPlug is compressed by hand and inserted into the hole stopping or reducing the inward flow of water as the foam returns to its original shape. 
TruPlug can also be cut with a razor knife and forced into elongated openings using a putty knife or similar tool. 
TruPlug can be inserted into the ends of broken pipes by twist compressing before inserting and will need to be held in place. 
TruPlug should be included with your damage control kit and kept with your vessel.
