Alkotest TR3225 plastic tee connector 32/25/32 mm for piping systems

Alkotest TR3225 plastic tee connector 32/25/32 mm is a three-way fitting designed for creating a stepped junction between pipes with outer diameters of 32 mm and 25 mm. Intended for use in plumbing and drainage installations, this reducer tee allows a main 32 mm run to branch into a 25 mm line and continue as 32 mm on the opposite side. The connector is manufactured from durable plastic suitable for non-pressurized or low-pressure drainage and waste systems commonly found in residential and light commercial settings.

Advantages

The Alkotest TR3225 offers a compact and lightweight solution for reducing and branching pipe runs without the need for complex adapters. Its molded design ensures consistent internal geometry for reliable flow transition between diameters. The plastic construction resists corrosion and is dimensionally stable under normal indoor conditions, simplifying installation and reducing long-term maintenance compared with metal alternatives.

Suitable for

• Domestic wastewater and drainage lines
• Branching sink, basin or appliance outlet lines to a main drain
• Light commercial plumbing where stepped tee connections are required
• Retrofit or repair projects requiring a 32 mm to 25 mm reduction in a three-way junction

Key specifications

• Configuration: three-way (tee) reducer
• Pipe diameters: 32 mm / 25 mm / 32 mm (outer diameters)
• Material: plastic (polymeric plumbing-grade material)
• Application: drainage, wastewater, and non-pressurized piping systems
• Compatibility: designed for use with compatible 32 mm and 25 mm plastic pipes and fittings

How to use

Select the Alkotest TR3225 when a stepped tee connection is required between 32 mm and 25 mm pipes. Ensure pipe ends are clean, free of burrs and cut square for proper fit. Push-fit, solvent-weld, or socket connection methods may be applied according to the pipe system and local practice; follow the joining method appropriate to the pipes in use. After installation, verify alignment and slope for drainage, and check for secure seating to prevent leaks in the assembled system.

Usage recommendations

Use the connector only within its intended application range: non-pressurized or low-pressure drainage and wastewater systems. Confirm compatibility with the specific pipe material and joining method (push-fit, adhesive, or socket) before installation. Avoid exposure to direct sunlight for prolonged periods if installed externally, and observe local plumbing codes for proper venting and slope requirements.
