## Long description

SiGMA-Li PERTZW1612T is a compression/welded transition fitting designed for use with PE-RT (polyethylene of raised temperature resistance) piping. The connector provides a female (GW) threaded outlet sized 16 x 1/2" to link PE-RT tubing with standard 1/2" threaded valves, fixtures or components. The fitting is intended for plumbing and heating systems where a secure, leak-resistant connection between plastic pipe and metal-threaded parts is required.
Advantages
The design of this SiGMA-Li fitting combines a compression-style interface for PE-RT pipes with a female threaded connection to simplify installation of mixed-material systems. It offers reliable mechanical grip on PE-RT tubing and a standardized 1/2" threaded port for compatibility with common fixtures. The fitting supports sealed transitions without the need for complex adapters and is suitable for installations where a compact, straightforward connection is preferred.
Suitable for
 Connecting PE-RT pipes to 1/2" threaded valves and fittings
 Residential and commercial plumbing lines using PE-RT tubing
 Underfloor heating manifolds and branch connections
 Retrofit jobs linking plastic piping to existing threaded components
Key specifications
 Pipe compatibility: PE-RT (polyethylene of raised temperature resistance)
 Connection type: compression/welded interface for pipe to female threaded outlet
 Thread size: female 16 x 1/2" (1/2" BSP/G-type compatible threaded outlet)
 Application area: plumbing and heating systems
 Material characteristics: designed for use with flexible plastic piping and metal-threaded components
How to use
Cut the PE-RT pipe squarely and ensure the pipe end is clean and free of burrs or debris. Slide the compression components onto the pipe as specified by the fitting design, insert the pipe fully into the fitting's socket, and secure the compression ring or nut according to the manufacturer's recommended torque. Thread the receiving 1/2" component into the female outlet, using an appropriate sealing method on the threads if required by the installation practice. Verify alignment and tighten to achieve a secure, leak-free connection while avoiding over-tightening that could damage threads or deform the plastic pipe.
Usage recommendations
Use compatible PE-RT pipe diameters and follow local plumbing codes. Inspect connections after initial system pressurization and during commissioning. For installations involving hot-water heating, ensure the fitting and pipe are rated for the system temperature and pressure. If uncertain, consult technical documentation or a qualified installer to confirm correct assembly and torque values.
