The T-piece branch connector for air tightness readings (CPT) is a galvanised steel accessory used to join the vertical collector system and horizontal ducting while enabling accessibility to the vertical riser and horizontal ducting as per the requirements of DTU 68.1 and 68.2. It is specifically designed for risers opening out into attics or flat roofs of commercial and multi-occupancy residential buildings, for which the airtight reading is made after the T-piece is installed. The T-piece branch connector is fitted with a stop ring on the piece body to hold the plug in a stable position and limit the risk of leaks.
