StockCap offers an extensive selection of tube caps and tube plugs. Sizes are available for round, square, and even rectangular tubing. Material selections range from high density polyethylene to soft PVC vinyl with specialty formulas for high temp paint masking applications. Some tube caps also feature tabs for easy removal or square ends that can keep packaging tubes from rolling when stacked on a store shelf.

One of our more common applications for tube caps and plugs is for use on mailing tubes. Our VisiPak division manufactures and stocks a complete line of plastic mailing tubes with a number of end cap and plug options.

StockCap tube plugs also come in a wide variety of styles and materials. Our economical T-Plug line is excellent for use as shipping protectors and dust covers while our vinyl plus plugs serve the same applications with added protection, sealing, and heat and chemical resistance. We also have over 20 rubber tube plugs in sizes to fit up to 1-1/4 inch diameter tubing.
