What are MDPE fittings?
MDPE fittings are connectors designed for use with medium-density polyethylene (MDPE) pipework, commonly used for underground water supply and mains water installations.
They provide secure connections between sections of MDPE pipe and allow pipework to be joined to other components, such as copper pipe, valves and taps.
MDPE fittings are available in a range of sizes and configurations to suit different pipework requirements.
What are Plasson MDPE fittings?
Plasson is a well-established manufacturer of MDPE compression fittings for water supply applications. Its range includes couplings, tees, elbows, adaptors, stop taps and other fittings designed to connect and control MDPE pipework.
Many Plasson fittings are WRAS approved for use in potable water applications. Always check the individual product specification before installation to confirm its certification and suitability.
What are MDPE fittings used for?
MDPE fittings can be used to:
- Join two lengths of MDPE pipe
- Change the direction of pipework
- Create a branch connection
- Connect MDPE pipe to other pipe materials
- Connect MDPE pipe to taps and valves
- Shut off or control water flow
- Repair or modify existing water supply pipework
What size MDPE fittings do I need?
The fitting needs to match the size of the MDPE pipe being connected. Common sizes include 20mm, 25mm, 32mm, 40mm and 63mm, although other sizes are available.
It's important to check the actual pipe diameter before ordering rather than relying on the size of an existing fitting.
For example, a 25mm MDPE pipe requires a compatible 25mm fitting. If you're connecting MDPE to another type of pipe, such as copper, you'll need an adaptor with the appropriate connection sizes.
What is blue MDPE pipe used for?
Blue MDPE pipe is commonly used for potable water supply installations and underground water mains. The blue colour makes water pipework easy to identify.
The fittings used with the pipe must be compatible with the pipe size and intended application. For drinking water installations, check that the individual fittings are approved for potable water use where required.
What types of Plasson fittings are available?
Plasson MDPE fittings are available in a range of configurations, including:
- Couplings: Join two lengths of MDPE pipe together.
- Tees: Create a branch from the main pipe run.
- Elbows: Change the direction of the pipework.
- Adaptors: Connect MDPE pipe to other pipe types or threaded components.
- Stop taps: Provide a means of shutting off the water supply.
- Valves: Control or isolate water flow within the system.
How do I choose the right MDPE fitting?
Before ordering an MDPE fitting, check:
- The diameter of the MDPE pipe
- The type of connection required
- Whether you need a straight connection, elbow, tee, adaptor or valve
- Whether the fitting needs to connect to another pipe material
- The intended application
- Any required WRAS or other certification
If you're unsure which fitting you need, checking the pipe size and taking a photo of the existing installation can help identify the correct replacement.
