The prompt
A straight connecting brass coupling for connecting a pump group to a separation heat exchanger, body made of brass, for heating systems, PN 10, max. short‑term temperature up to 110 °C. Connection 1 (bottom): internal pipe thread G 1½" (ISO 228-1 / BSPP), thread length 11 mm, with a flat sealing surface (flat seat for a gasket) at the open end of the thread. Connection 2 (top): internal pipe thread G 1½" for a free hexagonal union nut (ISO 228-1), length 11 mm, flat sealing socket on the shoulder; nut with a hexagon on the flat faces. Outer diameter of the body 38 mm, wall thickness 4 mm, total length of one adapter 65 mm. Smooth cylindrical outer surface, no logos or knurling.
