How to choose the proper size of hose clamp?
1. How to choose the proper size of hose clamp
First, measure the diameter of the hose. After measuring, the diameter of the hose is about 30mm. Let's take the installation of the British hose clamp as an example, and then look up the specifications of the hose clamp including 30 in the British hose clamp specification table, including 22-32 and 25-38. The standard for selecting the size of the hose clamp is to select the small one instead of the large one, which can save time and effort during installation and make it beautiful after installation.
Note: the size of the hose clamp is in mm. As long as the diameter of the pipe is within the scope of the hose clamp specification, it can be used. There are two or more specifications when choosing the size of hose clamp, so we should choose the smaller one.
Under what circumstances should the size of hose clamp be larger than small?
When the water pipe is not disassembled and the hose clamp needs to be removed, it is necessary to select the large one instead of the small one. When the small one is selected, it is very difficult to insert the disassembled hose band into the throat clamp head, and the large-sized one is much easier.

2. Connection depth of hose
In general, the insertion depth of the hose is 40mm, and the fixed position of the hose clamp is 20-30mm. If the surface of metal water pipe is corroded, sealant can be applied.
During installation, the inner part of the hose should be moistened so that it can be inserted smoothly and will not damage the hose. After the hose is connected with the iron water pipe, the rubber tube must have wrapping force, and there must be no gap between the metal water pipe and the rubber tube, that is to say, supporting products are required.
3、 Installation and tightening method of hose clamp
Select a screw driver or a special hose clamp wrench, turn it clockwise until the position of the clamp is concave about 0.5mm. After tightening, wait for 30 minutes, there is no leaching liquid, and the installation is qualified.
