MDPE Tee Reducing 25mm – 20mm is a compression fitting designed for MDPE piping, letting you connect a 25mm mains run to a 20mm branch with a tight, leak-free seal. Built for tradespeople, installers and keen DIYers, it supports water supply, irrigation and light industrial piping with reliable performance. This MDPE PN10 fitting is rated for up to 10 bar (1 MPa / 145 psi), making it suitable for typical domestic and irrigation systems. It uses MDPE material, which offers durability and chemical resistance, helping to safeguard against corrosion and chemical attack in residential and commercial environments. The connection employs threaded compression fittings to deliver a secure seal when installed correctly, and the reducer design provides a smooth transition between pipe sizes without sharp pressure drops. Key features - Pressure rating: PN10 (up to 10 bar / 1 MPa / 145 psi) for standard water and irrigation systems - Material: MDPE with inherent chemical resistance and durability - Connection type: threaded compression to give a tight, leak-free joint when properly fitted - Function: 25mm to 20mm reducing tee for MDPE networks - Longevity: designed to withstand temperature variation and outdoor exposure - Versatility: suitable for potable water, irrigation, and general MDPE piping runs What it does for you - Enables a dry, reliable reduction from 25mm to 20mm within MDPE networks without replacing existing pipes - Provides a practical solution for retrofit projects, garden irrigation loops, and new sections of pipework - Reduces the need for copper or alternative plastics where 25mm supply lines feed 20mm branches Applications and scenarios - Domestic water supply extensions and garden irrigation paths - Retrofit work where a 25mm main feeds a 20mm sub-branch - Short, cost-effective connections in MDPE piping systems for tradespeople and contractors Installation tips - Clean and deburr pipe ends before assembly - Insert pipes fully into the compression fittings and tighten per manufacturer guidance - Check for leaks after pressurising the system and re-tighten if required - Use compatible MDPE pipe and ensure the system remains within PN10 limits This reducer tee offers a practical, code-aligned solution for connecting MDPE pipes with confidence, supporting durable, leak-free water and irrigation networks.
