Rough, but common mistakes when installing threaded connections with your own hands.

Pipeline installation is rarely done without threaded connections. Usually this docking option is the main, but at the same time vulnerable element of the system.

As practice shows, when installing such a simple at first glance connection, allowed sometimes elementary mistakes.

As a result, this leads to a lot of problemsstarting from simple "digging" at the junction and ending a serious communal accident with all the ensuing consequences.

To prevent this from happening, it is better to find out before editing what mistakes should not be made. They will be discussed below.

Mistake # 1: Additional sealing of the thread for the connection with the union nut.

Flexible eyeliner and American already have a sealing rubber in the kit, which ensures the tightness of the connection.

therefore additionally compact carving flax, FUM-tape and other sealsnot worth it.

This can interfere with, when tightening the union nut until it stops, tightly fix the sealing rubber.

Mistake # 2: Winding flax counterclockwise.

If you wind it counterclockwise, then when tightening the thread flax will start to puff up and it will be more difficult to ensure the tightness of such a connection.

Flax needs to be wound in the direction of thread twisting, i.e. clockwise.

Mistake # 3: Using flax for thread sealing without protection (investment paste, red lead).

Linen is a natural material that is unprotected in a threaded connection over time starts to rot and the tightness is broken.

Therefore, when using flax as a sealant, it must always be protected with investment paste or red lead.

Mistake # 4: Using FUM tape instead of packing paste to protect flax.

FUM tape is not suitable for protecting flax when mounting threaded connections. She happens to be with a separate independent seal.

Although, in my opinion, it is still better to use good old linen with investment paste.
