FAQs
Is this fitting suitable for hot water pipes?
No, it is designed for cold water use only with a maximum temperature of 45 degrees Celsius.
Can I use this with copper pipes?
No, this compression coupler is designed exclusively for MDPE plastic piping.
Do I need plumber's tape for this connection?
Generally, no. The compression fitting relies on an internal seal to remain watertight.
Can I bury this fitting underground?
Yes, it is suitable for underground irrigation and water supply lines, provided it is installed correctly.
What is the maximum pressure this can handle?
This connector is rated for pressures up to 10 bar.
Is this reusable?
Yes, you can disassemble the connection and reuse the fitting on other 20mm MDPE pipes if necessary.
Troubleshooting
Water leaking from the connection
Ensure the pipe is pushed fully past the internal seal and tighten the nut further using a wrench.
Pipe slides out of the connector
Verify that the internal split-ring is correctly placed and that the pipe was inserted deep enough into the fitting.
Nut is difficult to tighten
Check the threads for dirt or debris and ensure the pipe is inserted perfectly straight into the fitting.
Pros and Cons
Pros
- No specialized plumbing tools required
- Highly durable and corrosion-resistant construction

Setup, Compatibility & Care
To install, slide the compression nut and the split ring onto the pipe, then push the pipe fully into the body of the connector. Hand-tighten the nut initially, then use a wrench for an additional quarter-turn to lock it. This product is only compatible with standard 20mm MDPE pipe. For long-term care, avoid over-tightening the plastic nuts as this can cause cracking. If the fitting is buried underground, ensure there is no stress on the joint from shifting soil or heavy weight above.
