StockCap offers an extensive selection of vinyl 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. View our Material Selection Guide for details. Some tube caps also feature tabs for easy removal. Other styles of caps for tubes include square shapes that 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 the popular mailing tubes. VisiPak, another division of Sinclair & Rush, manufactures and stocks a complete line of plastic mailing tubes or Tube-velopes. Each size of tube diameter is sold in varying lengths, but for each diameter our vinyl end caps are available in our standard colors. Tube-velopes are sold online with black or red vinyl tube caps.
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 such as sealing and heat and chemical resistance. (View our High Temperature Vinyl Guide.) We also have over 20 rubber tube plugs in sizes to fit up to 1-1/4 inch diameter tubing.
