How to bend the radiator plug 4 minutes and 6 minutes 1 inch?

You can measure radiator plugs with a tape measure to distinguish between 4 points, 6 points and 1 inch.

4 o'clock is 15mm, 6 o'clock is 20mm, and 1 inch is 25 mm.

Generally, heating pipes have three calibers: 4 minutes, 6 minutes and 1 inch, of which 6 minutes is the most common, and 4 minutes and 1 inch are special. The inner and outer diameters of the three pipe diameters are shown in the following table. Users can measure their own heating pipes in advance before choosing to avoid the mismatch between the pipes and the radiators.

Precautions for using radiator:

The valve on the heating pipe cannot be opened and closed at will. When the heating system runs for the first time, it usually needs debugging. Every household should adjust the valves of each riser to a proper position in time, open the manual bleeder valve of each radiator to exhaust the air gathered in the radiator, or open the exhaust valve of the gas collecting tank installed at the top of the system to exhaust until the radiator heats up and the debugging is completed.

Try to keep a certain heat dissipation space near the indoor radiator. Don't pile up sundries on or in front of the radiator, otherwise it will affect the heat dissipation effect of the radiator.
