The couplings are supplied assembled and packed in individual plastic bags with the size of the product.
For the convenience of transportation products are packaged in a common transport packaging according to the table.

The use of clamping couplings

Steel galvanized clamping couplings are used as the connecting element of water and heating supply.

The design of the clamping coupling

Body and nut
Due to the faceted body and the nut, screwing of the coupling has become more safer: the likelihood of slippage of the tool is decreased. Are made of malleable iron.
Clamping ring
It securely holds the pipe. Coupling clamp design fits different diameter within nominal pipe. It made of high strength spring steel.
Sealing sleeve
Securely seals the connection. It made of EPDM-rubber.
Washer
It protects the sealing sleeve from the mechanical action of the clamp ring and limit the indentation depth of the sealing sleeve into the body of the coupling. It is made of steel.
