Plastic Tee Connector SiGMA-Li TZ2012 with 20 mm (1/2") Threaded Branch - PP plumbing fitting

SiGMA-Li TZ2012 is a polypropylene (PP) tee connector engineered for plumbing systems that require a 20 mm (1/2") threaded branch. The fitting connects three pipe lines in a T configuration while providing a reliable threaded outlet for attachments such as taps, valves or small auxiliary lines. Constructed from corrosion-resistant PP, the connector is suitable for potable water distribution and general plumbing applications where a durable, chemical-resistant plastic fitting with a 1/2" threaded branch is needed.

Advantages

The polypropylene construction delivers chemical resistance, low weight and resistance to scaling, making the fitting suitable for long-term water distribution. The integrated 20 mm (1/2") threaded branch offers a standardized connection point for common fixtures and accessories, simplifying installation of taps or branch lines without additional adapters. The tee design ensures stable flow direction and straightforward integration into existing PP piping systems.

Suitable for

• Distribution of potable water in residential and light commercial plumbing
• Creating a threaded tap-off for sinks, appliances or outdoor taps
• Branching auxiliary lines for irrigation or secondary circuits
• Replacement or retrofit in systems using polypropylene piping

Key specifications

• Material: polypropylene (PP)
• Connection type: tee with one threaded branch
• Threaded branch diameter: 20 mm (1/2")
• Configuration: three-way T connector
• Application: potable water and general distribution

How to use

Prepare pipe ends by cutting square and deburring to ensure proper seating. Install the straight PP pipe segments into the tee sockets according to the system's connection method (socket weld, solvent, or push-fit as applicable for the piping system). Thread fixtures or valves onto the 20 mm (1/2") threaded branch, using appropriate sealing tape or sealant on the male threads to prevent leaks. Verify alignment and secure connections according to standard plumbing practice, then pressure-test the assembled section before putting it into regular service.

Usage recommendations

Use compatible PP pipes and follow the piping system manufacturer's instructions for jointing methods and temperature/pressure limits. Avoid exposure to direct flame or high temperatures beyond PP material specifications. When connecting metallic fixtures, ensure threads and seals are compatible to prevent galvanic effects and leaks.
