Elbows - internal thread

This category includes threaded elbow fittings designed for connecting polyethylene (PE) pipes to external threads in plumbing and heating systems. The fittings are constructed from brass CW617N and CW614N, with NBR and stop O-rings for sealing. They operate within a temperature range of -20 °C to +90 °C and are suitable for use in systems requiring corner connections between PE pipes and threaded components.

These elbows are commonly used in residential and commercial installations where PE piping is connected to metal components such as valves, meters, or radiators. They are ideal for applications involving water, heating fluids, and irrigation systems where flexibility and durability are required.

How to choose

• Select the correct PE pipe size and thread size combination (e.g., 20x1/2", 25x3/4") based on the system layout and flow requirements.
• Ensure compatibility with the PE pipe type and external thread specifications of the connected component.
• Verify that the operating temperature of the system does not exceed -20 °C to +90 °C.
• Confirm that the fitting is suitable for the intended pressure rating (PN 16) and fluid type.

Frequently asked questions

What materials are used in the construction of these elbows?
The body is made from brass CW617N, the clamping ring from brass CW614N, and the sealing rings are made from NBR and a stop O-ring.

Can these fittings be used with PE-RT or other types of PE piping?
Yes, provided the PE pipe is compatible with the clamping ring and the system operating conditions match the specified temperature and pressure range.
