This guide is for plumbers, DIY enthusiasts, and anyone working with 20mm MDPE pipes who needs to reliably stop water flow. The key benefit is a secure, pressure-resistant seal for underground cold water systems. A potential consideration is that it is specifically designed for 20mm MDPE pipes, requiring accurate sizing. This 2-pack of AB Tools MDPE End Caps features a durable polypropylene construction with an impact-resistant nut and body, designed to perform well under pressure and withstand significant thermal and mechanical stress. It's ideal for closing off pipe lines in various cold water applications.

This end cap is designed specifically for 20mm diameter Medium Density Polyethylene (MDPE) pipes.
No, these fittings are designed for cold water systems and are rated for specific temperatures and pressures within that context. They are not suitable for hot water.
The fitting has a pressure rating of 16 bar at 20°C. Pressure ratings decrease at higher operating temperatures.
Ensure the MDPE pipe end is clean, smooth, and cut squarely. Insert the pipe fully into the fitting and tighten the compression nut securely with a wrench (approximately 1/2 to 3/4 turn past hand-tight).
MDPE stands for Medium Density Polyethylene, a common type of plastic pipe used for water distribution.
This product meets standards including UNI 9561-9562, UNI EN 712-713-715, UNI ISO 7/1, ISO 14236, and UNI 2233.
While removal is possible, the compression seal may be compromised. For critical applications, it is recommended to use new fittings after removal to ensure a reliable seal.
Ensure the pipe is fully inserted and the compression nut is tightened sufficiently (typically 1/2 to 3/4 turn past hand-tight). Check for any debris or damage on the pipe end or fitting.
Verify that you are using a 20mm MDPE pipe and that the pipe end is clean, round, and free of damage. Slight warming of the pipe end might help in colder conditions, but avoid deforming the pipe.
The pipe may not be fully seated. Remove the nut and re-insert the pipe, ensuring it goes all the way in. Re-tighten the nut securely.
Setup: To install the AB Tools 20mm MDPE End Cap, ensure the end of the 20mm MDPE pipe is clean, free from burrs, and cut squarely. Slide the impact-resistant nut onto the pipe, then insert the pipe fully into the fitting body. Hand-tighten the nut, then use a wrench to tighten it a further 1/2 to 3/4 turn to secure the compression seal. Do not overtighten.
Compatibility: This fitting is specifically designed for use with 20mm diameter Medium Density Polyethylene (MDPE) pipes.
Care: As this is a permanent or semi-permanent fitting, minimal care is required after installation. Ensure the surrounding area is clear of obstructions. If the fitting is installed underground, it should be protected from direct impact and extreme localized stress.
