Product Information
Full details
The Securplumb Straight Compression Coupler is designed for DIY enthusiasts and professional plumbers who need a reliable, leak-free method to join 40mm waste pipes. Its primary benefit is the tool-free installation process that ensures a secure fit without the need for chemical solvents or specialized welding equipment, though users must ensure the pipe ends are cut perfectly square to guarantee a proper seal.

FAQs
Does this require any plumber's tape?
No, the compression mechanism relies on an internal rubber seal to achieve a watertight fit, so pipe tape is typically not needed.
Can this be used on pressurized water lines?
No, this fitting is strictly for waste and drainage systems, not for high-pressure supply pipes.
Is it compatible with PVC and ABS pipes?
It is generally designed for standard 40mm plastic waste pipes, but ensure the outer diameter matches the coupling specifications.
Can I reuse the fitting?
Yes, unlike glued fittings, this can be unscrewed and reused on different sections of pipe.
Do I need special tools?
Most installations can be completed by hand-tightening, though a pair of plastic pipe pliers may be used gently if needed.
Troubleshooting
Joint is leaking
Check that the pipe is inserted fully past the O-ring and ensure the rubber seal is seated correctly inside the coupler.
Nut will not tighten fully
Check the threading for debris and ensure the pipe is not wedged at an angle; the pipe must be perfectly square to the coupler.
Pipe slides out of coupler
Ensure you are using standard 40mm outside diameter waste pipe and that the compression ring is properly engaged.
Pros and Cons
Pros
- Simple installation without chemicals
- High compatibility with standard 40mm pipe
- Easy to remove and reuse
- Reliable watertight seal
Cons
- Requires clean, burr-free pipe ends
- Bulkier than solvent-weld fittings
- May require occasional tightening if exposed to heavy vibration
Setup, Compatibility & Care
Ensure that the 40mm waste pipe is cut cleanly using a pipe cutter or fine-toothed saw to prevent gaps in the compression ring. Remove any burrs from the cut edge with sandpaper to prevent damage to the internal O-ring. Keep the threading free of grit or debris to ensure smooth rotation. During long-term use, verify the connection annually if it is located in an accessible cabinet or crawl space to ensure the compression nut has not loosened due to thermal expansion and contraction.
