Threaded Caps

Threaded Caps, also referred to as thread protection caps, threaded plastic caps, or end cap threaded fittings, are commonly used to protect threaded components during transport, storage, and finishing processes. Used primarily by professionals across the manufacturing, engineering, and maintenance sectors, these caps are vital for preserving the integrity of threads and preventing contamination or damage.

Our range includes Metric, BSP, and UNF thread types to suit a wide variety of applications and fittings. These caps are manufactured from high-quality plastic (typically LDPE) and are available in multiple sizes, colours, and designs to fit both standard and custom specifications.
