End caps offer protection for your product during finishing, shipping, storage or transportation to the job site. These caps can also serve a critical function as masking caps, helping to protect exposed ends or openings from unwanted contamination or material accumulation during finishing work, such as painting, powder coating, anodizing, plating or e-coating.
Connection of end cap pipe fitting totally depends on service fluid and the nature of its hazards. Threaded type end cap may be with a male or female thread connection between pipe/tube and in other case end cap may be welded on to the end of the pipe/tube. The general purpose of end caps is to protect the end of pipe, equipment and other fittings, so the standard of end caps is the same as the pipeline.
