The invention disclosed and claimed is an improved plug with an internal anchor. The plug has particular utility in masking openings in parts to be coated. Generally, the plug comprises a compressible, resilient plug body and a compression mechanism. The compression mechanism compresses the plug body between an internal plug anchor and an opposed plug compression surface. The compressive force causes the plug circumference to increase forming a tight seal between the plug and walls forming the opening. The internal anchor design and absence of any axial opening through the entire plug body prevent fluids and other coating materials from passing through the internal plug body and into the interior of the part to be coated thereby avoiding costly damage to the part. |
