Abstract
A plug for sealing holes includes a body and at least three sealing ribs. The body is preferably hollow to save material and molding cycle time. A thickened area is formed at a rear of the body such that a screw driver may be used to insert the plug into a hole. The first sealing rib is formed at substantially a front of the body such that a lead-in area is formed on the body to facilitate easy insertion of the plug into a hole. The distance between each sealing rib is at least twice the greatest thickness of a single sealing rib.
Claims4
A plug for sealing a hole comprising:
- a body having a front and rear, a bore originating at said front and being formed through substantially the length of said body, a thickened area being formed at said rear of said body, said thickened area being thick enough such that a blade end of a screw driver will not break through to said bore during insertion of said plug for sealing a hole;
- at least three sealing ribs being formed around the periphery of said body, a first sealing rib of said at least three ribs being formed on substantially said front of said body such that a lead-in area is formed on said body, a plurality of circumferential ridges being formed on a front surface of said sealing ribs, a radial length of each said rib from an inner diameter to an outer diameter thereof being at least 35% of the outer diameter of said plug for sealing a hole;
- and
- said plug for sealing a hole being fabricated from material that is flexible enough to allow a single size of said plug for sealing a hole to seal a variation in hole size of at least 20 percent.
