Manufactured for the first time in 2010 upon request of a connector between a new gas meter and an old gas receiving installation, with obsolete threads.
With a general dimension of Ø 43 x 24 mm, this accessory allows to connect an old gas installation to a gas meter with new threads incompatible to the receiving installation, without having to dismantle the whole installation.
It consists of two male threads, a G 7/8" (ISO 228-1) and a W 42,7 x 14h” (BS84).
