## Long description

ALFA RK Tee Fitting PE, male thread 3/4" (20 mm x 3/4" x 20 mm) is a polyethylene tee designed to connect a 3/4" male-threaded component to a 20 mm PE pipeline. The fitting provides a secure transition between a PE distribution or irrigation pipe and a threaded branch for valves, taps or other threaded accessories. It is intended for water distribution and irrigation installations where a reliable threaded connection from 20 mm PE pipe is required.
Advantages
The tee fitting combines corrosion-resistant polyethylene ends with a durable male-threaded branch, ensuring long-term performance in standard plumbing and outdoor environments. Its simple geometry facilitates quick insertion and secure connection to 20 mm PE pipe, while the threaded branch allows direct attachment of threaded valves or fittings without additional adapters. The construction reduces potential leak points and offers compatibility with common irrigation and water distribution components.
Suitable for
 Connecting 20 mm PE distribution pipe to a 3/4" threaded valve or tap
 Irrigation systems and garden watering networks
 Secondary branches from main PE supply lines
 Outdoor plumbing where a threaded accessory must be fitted to PE pipe
Key specifications
 Material: polyethylene (PE) body with molded male metal-threaded branch
 Pipe connection size: 20 mm (two ends compatible with 20 mm PE pipe)
 Thread size: male 3/4" for direct threaded connections
 Configuration: tee (in-line PE to threaded branch)
 Intended medium: potable and non-potable water distribution and irrigation
How to use
Prepare the 20 mm PE pipe ends by cutting square and deburring to ensure a clean fit. Insert the PE pipe ends into the fitting according to the manufacturer's recommended insertion depth and secure them using appropriate joining methods for polyethylene (such as electrofusion, butt fusion, or approved mechanical compression/sleeve fittings) compatible with the fitting design. Screw the 3/4" male-threaded branch into the mating female threaded component, using an appropriate sealing method (such as PTFE tape or thread sealant) if required by the installation. Ensure all connections are tightened to the torque recommended for the threaded accessory to avoid damage.
Usage recommendations
Verify compatibility of the threaded accessory with a 3/4" male thread and follow local regulations for water systems. For outdoor or buried installations, protect the fitting from mechanical stress and prolonged UV exposure where applicable. Perform pressure testing of the assembled system according to industry standards before putting the line into regular service.
