TruPlug is a tapered circular cone shaped plug made of foam that is a solid spongy cellular material which is coated with a flexible sealer adding strength and colour.

Used as a temporary or emergency plug in boating applications where water would enter a circular oval or irregular hole caused by emergency maintenance or hull breach due to impact.

Compressed by hand and inserted into the hole stopping or reducing the inward flow of water as the foam returns to its original shape.

Can be inserted into the ends of broken pipes by twist compressing before inserting and will need to be held in place.

TruPlug can also be cut with a razor knife and forced into elongated openings using a putty knife or similar tool.
