GO Black Steel Cap Range Scr BSP BS EN 10241

Caps, usually liquid- or gas-tight, cover the otherwise open end of a pipe. A cap attaches to the exterior of a pipe, and may have a solvent-weld socket end or a female-threaded interior. The exterior of an industrial cap may be round, square, rectangular, U- or I-shaped, or may have a handgrip. If a solvent-weld cap is used to provide for a future connection point, several inches of pipe must be left before the cap; when the cap is cut off for the future connection, enough pipe must remain to allow a new fitting to be glued onto it.
