Invena reduction tee PE pipe fitting PE-25/20 for plumbing (MPN PE-63-025)

Invena reduction tee PE-25/20 is a polyethylene (PE) plumbing fitting designed to connect three sections of PE pipe while reducing the diameter from 25 mm to 20 mm on the branch. Intended for water distribution and general plumbing systems, this fitting provides a durable, corrosion-resistant connection suitable for potable water and non-aggressive fluid transport. The tee's molded design ensures consistent wall thickness and alignment for straightforward installation in residential and light commercial piping networks.

Advantages

The PE material offers good chemical resistance, flexibility and resistance to corrosion compared with metal alternatives, reducing long-term maintenance. The integrated reduction allows a clean transition between pipe sizes without additional adapters, minimizing potential leak points. Lightweight construction facilitates handling and positioning during installation, while the smooth internal surface helps maintain flow and reduces the risk of clogging.

Suitable for

• Potable water distribution lines
• Household plumbing networks
• Irrigation and garden water supply
• Branching supply lines where diameter reduction is required

Key specifications

• Material: polyethylene (PE)
• Connection type: three-way tee with reduced branch
• Main pipe diameter: 25 mm
• Branch pipe diameter: 20 mm
• Intended fluid: potable water and non-aggressive liquids
• Typical application: plumbing and water distribution systems

How to use

Select compatible PE pipes of the specified diameters and prepare pipe ends by cutting square and removing burrs. Use the appropriate joining method for the chosen PE system (e.g., electrofusion, butt fusion, or mechanical compression couplings) following manufacturer and applicable local codes. Ensure proper alignment and heating/cooling cycles if fusion methods are used. After joining, verify connections are secure and perform pressure testing in accordance with local regulations before placing the system into regular service.

Usage recommendations

Store the fitting away from direct sunlight and extreme temperatures prior to installation. When installing in potable water systems, use approved joining procedures and materials compatible with drinking water. Follow local standards for pressure testing and disinfection where required.
