Plastic compression tee Unidelta 25 mm (model 603025) for polyethylene piping connections

Unidelta plastic compression tee 25 mm (model 603025) is a three-way connector designed for polyethylene (PE) piping systems. It allows creating a branch in a 25 mm PE pipeline using a compression fitting principle, providing a mechanical seal between pipe and fitting without the need for adhesives or thermal fusion. The product is intended for water distribution, irrigation, garden systems and general plumbing applications where a reliable branch connection is required.

Advantages

The compression tee is made from durable plastic materials compatible with PE pipes and engineered to resist standard wear and exposure associated with water systems. Its compression fitting design simplifies installation and replacement, reducing the need for specialized tools or heat-based joining methods. The fitting provides a secure mechanical grip on the pipe and a watertight seal when installed according to manufacturer guidelines.

Suitable for

• Branching 25 mm polyethylene (PE) pipes in irrigation systems
• Garden watering and dripline networks
• Cold water distribution in residential or light commercial plumbing
• Temporary or permanent potable water installations where compression fittings are acceptable

Key specifications

• Connection type: compression fitting for polyethylene pipe
• Pipe size compatibility: 25 mm outer diameter PE pipe
• Material: engineered plastic suitable for water service
• Configuration: three-way tee for creating a branch
• Seal type: mechanical compression seal (no solvent or heat welding required)

How to use

Ensure pipe ends are cut square and free from burrs or debris. Slide the compression nut and any gasket components onto the PE pipe according to the fitting's assembly order, then insert the pipe fully into the tee body until it reaches the stop. Tighten the compression nut by hand and finish with a wrench if required, following recommended torque values from installation instructions. Check the connection visually and pressurize the system to verify there are no leaks. For secure results, confirm compatibility with the pipe wall thickness and material before installation.

Usage recommendations

Use the compression tee with polyethylene pipes that match the 25 mm nominal size and meet applicable standards for pressure rating and wall thickness. Avoid exposing the fitting to prolonged sunlight without UV protection and do not use with hot water systems beyond the fitting's intended temperature range. Periodically inspect connections for signs of looseness or wear and re-tighten according to the manufacturer’s guidance if required.
