PP-R BF fittings are mainly used for transitional connections with metal equipment, valves, or flange interfaces. Typical applications include:

Building water supply: The flange connection between pipelines and metal equipment such as water pumps, water meters, boilers, etc. in the cold and hot water supply system.

HVAC: Connection of PP-R pipelines and steel valves in heat exchange stations and air conditioning rooms.

Industrial fluids: Insulation transition between corrosive fluid transport pipelines and metal equipment in the chemical and food industries.

The applicable temperature range is usually -15 ℃ to 95 ℃, covering both domestic hot water and low-temperature heating conditions.
