De Dietrich 85565627 gas supply pipe, 7-8-9 sections

De Dietrich 85565627 gas supply pipe, listed for 7-8-9 sections, is a manufacturer-specific connection piece. The catalogue article is 336.835.003, with manufacturer codes 85565627 and 336.835.003. It falls under boiler pipes, flanges and connections. In a boiler or burner system, the gas supply pipe delivers fuel from the main gas line to the gas valve. It is a rigid or flexible metal section that must maintain a gas‑tight seal under operating pressure. Because the geometry of the pipe is determined by the appliance frame and the position of the gas valve, a part of this type is designed for a particular combination of boiler sections – here, units with 7, 8 or 9 sections. The pipe works directly with the gas valve, the burner control, and the upstream gas filter or shut‑off valve. When replacing a gas supply pipe, confirm the thread type and size on both ends, the overall length and the routing clearances. Sealing method (taper thread with sealant, flat gasket, or O‑ring) must match the original. Manufacturer‑specific gas pipes such as this one rarely have direct generic equivalents, because the bend angles, union positions and support brackets are fixed by the boiler model. Always verify the section count and the appliance series before ordering.
