Cap plugs are protective fittings which keep the open ends of pipes, hoses or tubes covered during storage and transportation. They prevent dust, dirt and other contaminants from collecting round the open edges and damaging the threaded ends of the pipe. Another useful property of caps and plugs is that they can be used to cover sharp edges of tubes used to construct display shelves and thus prevent injury to people who brush against them accidentally. They also provide a good finish to exposed ends of bolts, screws and other fitments by keeping them covered against corrosion by exposure to moisture and air. Tamper-proof and tamper-evident caps are essential while storing and transporting volatile, hazardous or toxic substances. Threaded caps are also available.

Generally the materials used to manufacture cap plugs are : Aluminum (for special requirements), rubber and rubber compounds like silicone rubber, plastics and PVC compounds including polyethylene both high and low density, vinyl, nylon and polypropylene. These materials are available in a huge variety of colors, textures, sizes, dimensions and finishes. Color and texture coding are required for certain types of applications. Many manufacturers offer free samples and catalogs so that you can pick the right type of cap plugs for your requirements.

Some of the options available are:

Threaded cap plugs: Made of aluminum for heavy-duty sealing applications or vinyl/polypropylene for others, these caps also come in a nosed, flared design which creates pressure sealing. Some of them come with knurled covers and are excellent to keep out dirt and moisture, especially during re-decorating, painting or polishing processes. Caps for threaded pipes/tubes etc can also be fitted over any cylindrical surface.

Vented: used in medical tubing and fitments during sterilization procedures, shipment and storage. The vents prevent pressure build-up.

Pull/Tear tab: have a pull-off tab for tearing off or for easy grip while removal. The tear-off type is suitable for tamper-evident applications.

Butt-weld: for heat exchangers, valves and pumps.

Heavy-duty, wide-flange: these keep the cap or plug from being accidentally removed, pulled-off or being forced down the opposite part during shipment and handling.

Finishing: these cap plugs can be slid over the open/exposed ends of tubes and pipes and give an attractive, neat finish. They can be used to cover the rough ends of metal furniture in patios or outdoor seating areas, display shelves, supermarket trolleys, garden equipment like wheelbarrows and lawnmowers, exercise equipment in gyms to prevent injury due to accidentally brushing against sharp ends. Another great way to use these is when there are small chipped/cracked ends or scratches which occur on the pipe or tube during cutting.

Depending on your needs and requirements, you can order cap plugs from on-line suppliers or purchase them from your local hardware stores.
