hp-Technik 22/24 coupling

The hp-Technik 22/24 coupling is listed under catalogue article 543.505.008, with manufacturer codes 0820675 and 84139100, in the category of oil filters, coils, tubes & hoses. This coupling is a component used in the oil supply line of a burner system. In an oil burner, the coupling connects sections of tubing or joins components such as the oil filter, the pump, and the nozzle line. It ensures a leak‑tight join that can withstand the operating pressure of the oil circuit. Parts of this type are selected by connection thread (BSP, metric, or NPT), tube diameter, and material compatibility with heating oil. When replacing such a coupling, confirm that the thread size and seal type (tapered or parallel) match the existing ports. Check that the material is suitable for the fuel and pressure – brass or steel are common, but the exact specification should be verified from the original part. A mismatched coupling can cause leaks or restrict flow, leading to poor burner performance or safety hazards.
