Reducing T-piece Unidelta PE fitting 32 mm x 5/4" x 32 mm, model 603633

Unidelta reducing T-piece model 603633 is a polyethylene (PE) pipe fitting designed for creating a branch with a reduced connection in PE piping systems. The fitting has two 32 mm ends and a central reduced 5/4" (1¼") connection intended for threaded or socket use, allowing a compact transition where a main line continues and a smaller or threaded branch is required. It is suitable for use in water distribution, irrigation and utility networks where a reliable PE-to-threaded or reduced branch is needed.

Advantages

The reducing T-piece combines corrosion-resistant PE construction with a compact geometry that reduces installation space and simplifies branching. Its design enables a clean reduction from 32 mm to a 5/4" central connection, providing compatibility with threaded components or socket fittings. The fitting offers mechanical stability under normal operating conditions of non-pressurized and low-pressure potable water and irrigation systems and requires minimal maintenance due to the inherent durability of polyethylene.

Suitable for

• Water distribution mains and branches
• Irrigation systems and garden watering networks
• Utility networks requiring a reduced or threaded branch
• Repairs and modifications of existing PE pipelines

Key specifications

• Material: polyethylene (PE)
• Connection configuration: reducing T-piece with two 32 mm outlets and one central 5/4" (1¼") connection
• Central connection type: suitable for threaded or socket attachment
• Application: water distribution, irrigation, utility pipelines
• Design characteristic: compact branch and reduction geometry for space-saving installations

How to use

Prepare the PE pipe ends by cutting squarely and removing burrs, then ensure the pipe surfaces are clean and free of debris. Insert the 32 mm PE pipes into the respective outlets according to the chosen joining method (electrofusion, butt fusion or mechanical compression compatible with PE). Connect the central 5/4" branch using a matching threaded fitting or socket adapter as appropriate for the system. Follow the joining method manufacturer’s instructions and applicable local standards for pressure testing and system commissioning.

Usage recommendations

Verify material compatibility and pressure ratings of mating components before installation. Use proper fusion or mechanical connection techniques suitable for PE fittings and consult local regulations for potable water installations. Store the fitting away from direct UV exposure when possible and avoid prolonged contact with sources of high temperature or aggressive chemicals.
