Product Information
Full details
The 15mm Compression End Cap Stop End is an essential component for plumbers and DIY enthusiasts who need to terminate copper or plastic pipe runs quickly and reliably. Designed for use in hot and cold water systems, as well as air and oil supplies, these fittings deliver a robust, leak-proof seal without the need for heat or solder. While they offer exceptional ease of use, it is important to ensure the pipe ends are perfectly deburred and clean before installation to avoid potential weeping under pressure.

FAQs
Can I use these on plastic pipe?
Yes, these are suitable for plastic pipe, but you must use a pipe insert to maintain the pipe's shape under compression.
Do I need to use PTFE tape?
Generally, compression fittings seal using the olive alone. However, some professionals use a small amount of PTFE tape or jointing compound as an extra precaution.
Are these suitable for gas lines?
No, these are rated for water, air, and oil. Never use these compression fittings for gas supplies.
Can these be reused?
The fitting body can be reused, but it is highly recommended to replace the olive if you take the joint apart, as they deform during the initial tightening.
What tools do I need for installation?
You only need two adjustable wrenches (or spanners) to tighten the nut while holding the fitting body steady.
Troubleshooting
Joint is weeping or leaking
Ensure the nut is tightened correctly. If it persists, remove the fitting, check that the pipe end is not scratched, and ensure the olive is seated squarely.
Nut will not tighten fully
Check the threads for debris or damage. Ensure the pipe is inserted fully into the fitting body so the threads can engage properly.
Pros and Cons
Pros
- No heat or soldering required for installation
- Suitable for both copper and plastic piping
- Meets WRAS and BS quality standards
- Easy to remove or reposition if maintenance is needed
Cons
- Requires proper pipe preparation to prevent leaks
- Over-tightening can deform the olive or damage the pipe
- Not suitable for high-vibration environments compared to soldered joints
Setup, Compatibility & Care
To install, ensure the pipe end is cut square and deburred to prevent damage to the internal olive. Slide the compression nut and olive onto the pipe, then insert the pipe fully into the body of the stop end. Tighten the nut by hand until firm, then use a wrench to tighten by an additional half to three-quarters of a turn. Avoid overtightening, as this can crush the olive. For long-term care, occasionally inspect the joint for signs of moisture. If a joint begins to leak, a simple quarter-turn of the nut is often sufficient to reseal it, though the olive should be replaced if it has become excessively deformed or scored during previous installations.
