PPR End plug long with o-ring

The PPR threaded plug, long with O-ring, is a white PP-R end plug with a 1/2" BSP parallel (G) male thread that temporarily closes female threaded outlets, such as tap and concealed shower mixer connections, so a hot and cold water installation can be pressure tested before fittings are installed. Its long body reaches outlets set deep behind tiles, and the O-ring seals without thread tape or hemp.

The PPR threaded plug, long with O-ring, closes a 1/2" female threaded outlet in a PP-R water installation. It is made of PP-R (polypropylene random copolymer, type 3) to EN ISO 15874-3, is rated PN25, and has an operating temperature of 70 °C with a maximum of 95 °C. It is part of the THERMALINO Eternal line of PPR fittings and comes in white. On a building site, taps, faucets and mixers are usually fitted only at the end of the work, so that they are not damaged while construction goes on. Until then, their connection points are open. This plug screws into those outlets so that the system becomes a closed circuit and can be pressure tested, and the installation checked for tightness before walls and floors are finished. When the fixtures are fitted, the plug is unscrewed. The long body is intended for threaded outlets that sit deep in the wall under the tiling, for example the connections of a concealed shower or bath mixer. The plug can be reached and removed after the wall is plastered and tiled. The plug has a 1/2" BSP parallel (G) male thread with an O-ring seal. Because the O-ring seals, the thread does not need PTFE tape or plumbing hemp, so the plug is fitted and removed quickly and cleanly, and outlets can be closed and opened again as the work progresses.
