管道配件中橡膠接頭，橡膠軟連接是需要帶配對的，是否帶配對是由管件的連接方式決定的。

比如橡膠軟連接將兩個管口連接起來，在左邊的管口上焊接一片，參數要和橡膠軟連接的參數相同，以方便對接，在管子上焊接的就是配對。不用配對的就需要焊接。

焊接有一個弊端那就是不易拆卸，因為與管子焊接在一起一旦需要拆卸就要把焊管的部分割開，才能取掉打開。

安裝這種油管接頭，比較關鍵的是要控制好是管子端部的擴口。

否則如果擴口過大，就會影響到密封效果，甚至有可能產生裂紋。

具體來說這種接頭的安裝，是需要大家注意在擰緊管接頭螺母時，緊固力矩要適度，擰緊時必須用力矩扳手。

其次是注意盡量一次操作好，如果是紫銅管拆卸一次再重新裝配，一定要更換新銅管，重新進行擴口再去裝入。

Rubber joints and rubber soft connections in pipe fittings need to be paired. Whether to pair or not is determined by the connection mode of pipe fittings.

For example, the rubber soft connection connects two nozzles, and one piece is welded on the left nozzle. The parameters should be the same as those of the rubber soft connection to facilitate docking. What is welded on the pipe is pairing. Those that do not need to be paired need to be welded.

One disadvantage of welding is that it is not easy to disassemble, because once it is welded with the pipe, the part of the welded pipe must be cut off before it can be removed and opened.

The key to installing this kind of tubing joint is to control the flaring at the end of the pipe.

Otherwise, if the flare is too large, it will affect the sealing effect and even crack.

Specifically, for the installation of this kind of joint, we should first pay attention to the appropriate tightening torque when tightening the pipe joint nut, and the torque wrench must be used when tightening.

The second is to try to operate well at one time. If the copper pipe is disassembled and reassembled, it must be replaced with a new copper pipe, flared again and then installed.
