Product Information

Full details

This Wall Flange Kit is designed for plumbing and irrigation professionals needing a secure, durable connection for MDPE (Medium-Density Polyethylene) pipes. Its key benefit is providing a leak-free seal and easy installation with robust brass and MDPE components. A key consideration is that PTFE tape is not included and must be purchased separately. The kit includes a 20mm MDPE Wall Flange and a 1/2" BSP Brass Barb straight joiner, offering a reliable solution for connecting pipes to flat surfaces and other threaded fixtures.

Extended Product Information

FAQs

What is MDPE?

MDPE stands for Medium-Density Polyethylene, a type of plastic commonly used for water and gas pipes due to its flexibility, durability, and resistance to chemicals and corrosion.

What does 1/2" BSP mean?

BSP stands for British Standard Pipe. It's a widely used standardized thread type for pipes and fittings, ensuring compatibility between different components. 1/2" refers to the nominal size of the thread.

Is PTFE tape included in the kit?

No, PTFE tape is not included in this kit. It needs to be purchased separately to ensure a watertight seal on the threaded connection.

What is the maximum pressure this kit can handle?

The MDPE fittings in this kit are rated for PN10, which means they can withstand a maximum operating pressure of 10 bars (approximately 145 psi).

Can I use this kit for drinking water?

While MDPE is commonly used for potable water, the suitability of the entire system depends on local regulations and the specific components used. Ensure all parts comply with potable water standards if intended for such use.

How do I connect the MDPE pipe to the fittings?

The MDPE pipe is typically inserted into compression fittings like the barb connector. For secure connections, especially under pressure, it's recommended to use MDPE clamps.

What is the purpose of the wall flange?

The wall flange provides a secure mounting point for the pipe to a flat surface, such as a wall, preventing strain on the pipe and ensuring a stable installation.

Troubleshooting

Connection leaks at the threaded joint.

Ensure PTFE tape is properly applied to the BSP threads before connecting. Check that the brass barb connector is securely tightened onto the fixture and the MDPE pipe is fully inserted into the barb.

MDPE pipe does not seal tightly in the barb fitting.

Ensure the pipe end is clean and cut squarely. For high-pressure applications, use a suitable MDPE clamp to secure the pipe to the barb.

Wall flange does not mount securely.

Use appropriate screws or anchors for the mounting surface. Ensure the surface is flat and capable of supporting the plumbing system's weight and pressure.

Corrosion or degradation of brass fitting.

While brass is corrosion-resistant, prolonged exposure to highly aggressive chemicals may cause degradation. Ensure the application is within the material's chemical resistance limits.

Pros and Cons

Pros

Provides a secure and leak-free connection for MDPE piping systems.
Durable construction with corrosion-resistant brass and MDPE materials.
Easy to install with threaded compression fittings, requiring no special tools.
Versatile for use in water supply, irrigation, and industrial applications.
PN10 rating ensures suitability for moderate pressure systems.

Cons

PTFE tape is not included in the kit and must be purchased separately.
Primarily designed for 20mm MDPE pipes; may not be compatible with other pipe sizes or materials without adapters.
Brass components, while durable, can be heavier than plastic alternatives.
Installation requires basic plumbing knowledge for proper sealing.

Setup, Compatibility & Care

Setup:

Prepare the Surface: Ensure the flat surface for the wall flange is clean, dry, and structurally sound.
Mount the Wall Flange: Securely attach the 20mm MDPE Wall Flange to the chosen surface using appropriate fixings (not included).
Connect MDPE Pipe: Insert the 20mm MDPE pipe into the flange fitting, ensuring it is fully seated.
Attach Barb Connector: Slide the 1/2" BSP Brass Barb connector onto the other end of the MDPE pipe. Secure it using an appropriate MDPE clamp (not included) if necessary for high-pressure applications.
Thread Connection: Apply PTFE tape (purchased separately) to the 1/2" BSP threads of the desired fixture and screw the brass barb connector into it.
Tighten Fittings: Hand-tighten all connections, then use appropriate tools for a final snug fit, taking care not to overtighten.

Compatibility:

Pipe Type: Designed specifically for 20mm MDPE (Medium-Density Polyethylene) pipes.
Thread Type: Compatible with 1/2" BSP (British Standard Pipe) threaded fittings.

Care:

Clean external surfaces with a damp cloth as needed. Avoid abrasive cleaners.
Periodically check all connections for tightness and signs of wear or leakage, especially after significant pressure fluctuations.
