Harman Corporation produces multiple types of plastic plugs and plastic caps that make your item arrive in pristine condition. We offer an extensive selection of tube caps and tube plugs with sizes available for round, square, and rectangular tubing. Choose from materials like soft PVC vinyl. We also create plastic caps with tabs for easy removal. We even create plastic caps with square ends to prevent tubes from rolling while on a store shelf. Harman corporation makes a variety of caps and plugs including:

Silicone Caps and Plugs: Silicone caps, with their soft flexibility and high heat tolerance (up to 600 degrees Farenheit), are some of our most versatile caps and plugs.

Vinyl Caps: Less expensive than other materials, vinyl plugs and caps are great for those looking for a cost-effective pakaging solution. Vinyl caps provide an airtight seal. Vinyl caps also insulate and cushion.
