Buderus H-block, G3/4"xG3/4" AG, Non preset, Straight

The Buderus H-block G3/4"×G3/4" AG (straight, non‑preset) provides a compact, in‑line coupling for connecting Buderus radiators and hydronic piping via G3/4" male threads. Its non‑preset design omits integrated flow balancing so installers can use external balancing or preset valves; the straight orientation simplifies piping runs and maintenance. I searched Bosch North America sites (bosch-homecomfort.com and bosch-climate.com) and did not find an official page or datasheet for part number 7738317846, so this description is based on the product name and category.
