Compression Elbow SiGMA-Li PERTKW1612T for PE-RT pipe 16x1/2" (16 mm x 1/2")

Compression Elbow SiGMA-Li PERTKW1612T for PE-RT pipe 16x1/2" is a 90° compression fitting intended for use with PE-RT pipes of 16 mm outer diameter. The fitting combines a compression connection on the pipe side with a 1/2" threaded outlet to create a durable change of direction in heating and plumbing systems. It is designed for installations where a compact elbow with a reliable sealed joint is required, including underfloor heating manifolds, radiator connections and potable water circuits.

Advantages

The compression elbow provides a secure, leak-resistant connection to PE-RT pipe without requiring soldering or specialized fusion equipment. Its compact 90° profile saves installation space and simplifies routing in confined areas. The use of a mechanical compression joint allows for relatively fast assembly and disassembly for maintenance, while the threaded 1/2" outlet ensures compatibility with common valves and accessories. Materials and construction are chosen to suit potable water and heating applications where corrosion resistance and stable joint performance are important.

Suitable for

• Underfloor heating manifolds and branch lines
• Radiator supply and return connections
• Domestic potable water pipelines using PE-RT 16 mm pipe
• Compact plumbing installations and retrofit projects

Key specifications

• Pipe compatibility: PE-RT with 16 mm outer diameter
• Connection type (pipe side): compression fitting designed for PE-RT
• Connection type (outlet): 1/2" threaded connection
• Angle: 90° elbow
• Application: heating and potable water systems

How to use

Cut the PE-RT pipe squarely and deburr the end, ensuring the outer diameter is clean and free of damage. Slide the compression nut and any included ferrule or sealing component onto the pipe, insert the pipe fully into the fitting body until it reaches the internal stop, then tighten the compression nut to the specified torque or hand-tight plus an appropriate fraction of a turn as recommended by the pipe manufacturer. Thread the 1/2" outlet to the mating fitting or valve using appropriate sealant or tape on the male threads if required. After assembly, perform a pressure test of the system according to local regulations and standards to check for leaks before placing the system into regular service.

Usage recommendations

Use with undamaged PE-RT pipe of the correct outer diameter and follow manufacturer guidance on tightening torque. Avoid excessive bending near the joint and support the piping to prevent stress at the elbow. For potable water systems, flush the line after installation and carry out a pressure test in line with applicable codes.
