Components of fittings and valves of Arm Pipe

Press Fittings

Pipe fittings are composed of four components. The first part of this type of fittings is made of brass, which is plated with nickel alloy for strength and beauty. O-rings are the next part of this type of connection. In order to prevent water leakage, in addition to the compression of the teeth of the connecting body in the inner flesh of the pipe, two silicone O-rings are used in each branch.

The stainless steel ring is the next part of this type of connection. When the connecting body is placed inside the pipe, this ring is fixed on the pipe and the pipe is actually restrained between the steel ring and the brass body. The holes are visible on this ring and it is ready for the ring to be pressed on it.

The last part of these press-arm pipe fittings are plastic restraints that are located at the end of the tooth of each branch and are used to maintain and restrain the steel ring on the body of the connection. By keeping the steel ring in place on the body of the connection, this restraint has increased the execution speed.

Coupling fittings

Coupling joints consist of three components. The body of the connection is made of brass with nickel alloy plating, and at the branching outlet of each connection, there are reverse teeth to keep the pipe in place. At the end of the tusks, the connection body has a thread for screwing the nut to it.

The second part of these O-ring connections, and the last part is the brass ring that holds the pipe. When the body of the connection is placed inside the pipe, this ring is placed on the pipe and the pipe is actually restrained between the ring and the body.
