Pipe Tee Unidelta 50 mm PE — 603050, polyethylene plumbing fitting

Unidelta PE pipe tee 50 mm (model 603050) is a polyethylene plumbing fitting designed to join three PE pipes with a nominal diameter of 50 mm. It provides a corrosion-resistant, lightweight connection point for potable water supply, irrigation and drainage systems where a branch is required. The tee is compatible with standard 50 mm PE pipes and is intended for use in buried or above-ground installations within its material and pressure ratings.

Advantages

The polyethylene construction offers chemical and corrosion resistance and reduces the risk of galvanic reaction compared with metal fittings. The fitting is lightweight, which simplifies handling and installation on-site. Its smooth internal surface helps maintain flow rates and minimise sediment buildup. Designed for reliable, leak-resistant joints with compatible PE piping, the tee supports common plumbing and irrigation layouts while requiring minimal maintenance.

Suitable for

• Branching potable water supply lines made from PE piping
• Irrigation networks for gardens, parks and agricultural plots
• Non-pressurised and gravity drainage connections where PE pipes are used
• Above-ground and buried PE pipeline installations within the material’s service conditions

Key specifications

• Material: polyethylene (PE)
• Connection size: nominal 50 mm for three ports
• Application: water supply, irrigation, drainage
• Properties: corrosion-resistant, lightweight, smooth internal bore
• Installation environment: suitable for buried and above-ground use within PE temperature and pressure limits

How to use

Prepare compatible 50 mm PE pipes by cutting square and cleaning pipe ends. Join the pipes to the tee according to the chosen PE joining method (for example, electrofusion welding, butt fusion or compatible mechanical couplers) following manufacturer instructions and applicable standards. Ensure proper alignment, allow welds or couplers to cool or set per recommended times, and test the assembled pipeline for leaks at the designed test pressure before placing into service.

Usage recommendations

Follow applicable local codes and the PE joining equipment manufacturer’s guidelines for fusion or coupling procedures. Store the fitting away from direct sunlight for extended periods and avoid exposure to temperatures outside the polyethylene material limits. Perform pressure testing after installation and maintain access points for inspection where required.
