1/2" CPL

1/2" CPL is a compact 1/2‑inch coupling intended as a Bosch replacement/service part for joining 1/2" pipe or fitting interfaces in heating, hot‑water and HVAC assemblies. Its simple form factor supports fast field service for installers and technicians, enabling a neat, service‑friendly connection that reduces on‑site labour and downtime. I was unable to locate the exact part number 873700134300010982 in Bosch’s spare‑parts catalogues, so this description is based on the part name and category; please confirm fitment against the unit parts list.
