The first new function: the connection is the old function, so I won't repeat it here, but if the grooved pipe is lined with plastic, in addition to the connection, it has the anti-corrosion function, is it brand new?
The second new feature, which you have never heard of before, can control the speed of water flow, and the level of water pressure threshold can be directly controlled. You know a product called a grooved pipe valve Yes, that's him, he is an upgraded version of the grooved pipe fittings, with functions that can be controlled freely.
The third new feature: The pipe fittings can be directly connected to the pipe fittings. There is no such model originally. Many times, we will encounter the problem of insufficient pipe length, so we can directly use the two to connect.
