ALFA RK Tee Fitting PE, male thread 3/4", 20 mm x 3/4" x 20 mm, model 603521

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.
