Diaphragme bp 3.95mm De Dietrich S101542

A diaphragm bp 3.95mm is a replacement part for gas valves or pressure regulators in heating systems. This specific thickness is critical for proper sealing and pressure modulation, ensuring your burner or boiler operates efficiently and safely. Over time, diaphragms can degrade, leading to performance issues; swapping in a new one restores correct gas flow control. Ideal for technicians servicing a range of gas-fired heating equipment.
