Product Information
Full details
The Plumbright Compression Blanking Disc (15mm) is designed for professional plumbers and serious DIY enthusiasts who need a reliable, permanent, or temporary method to seal off 15mm pipework. Its primary benefit is the ease of installation via a compression fitting, which eliminates the need for soldering or specialized tools; however, users should ensure the pipe ends are perfectly clean and deburred to guarantee a leak-free seal.

FAQs
Can this be used on plastic pipe?
Yes, provided you use a suitable pipe insert to support the inner wall of the plastic pipe.
Is this a permanent solution?
Yes, it is designed for long-term use, though it remains removable if the plumbing system needs to be extended later.
Do I need plumbers tape (PTFE) with this?
Compression fittings generally do not require PTFE tape as the seal is created by the compression of the olive/disc; however, a small amount on the threads can sometimes assist in tight spaces.
Can I reuse the blanking disc?
It is generally recommended to use a new olive and disc if you have disassembled a connection, as these components deform slightly to create the initial seal.
What tools do I need?
You will need two adjustable wrenches (spanners) to secure the fitting without twisting the pipe.
Troubleshooting
Visible leaking after installation
Ensure the pipe end is square and free of burrs. Tighten the nut an additional quarter turn, but do not overtighten.
Nut will not thread onto the fitting
Check that the nut is not cross-threaded and that there is no debris in the threads. Clean threads with a wire brush.
Fitting slips on plastic pipe
Ensure a pipe stiffener (insert) is used inside the plastic pipe to prevent it from collapsing under compression.
Pros and Cons
Pros
- No soldering or open flames required
- Easy to install with basic hand tools
- Reliable, leak-resistant compression seal
- Suitable for both copper and plastic 15mm pipework
- Compact design ideal for tight plumbing spaces
Cons
- Requires proper pipe preparation to prevent leaks
- Not suitable for extremely high-pressure industrial systems
- Must be tightened correctly to avoid crushing the pipe or disc
Setup, Compatibility & Care
To set up the blanking disc, slide the compression nut and the existing olive (or a new one if necessary) onto the 15mm pipe. Place the blanking disc over the end of the pipe, then screw the nut onto the fitting. Tighten with two wrenches: one to hold the body and one to tighten the nut. Compatible with all standard 15mm plumbing systems. For care, inspect the joint for any moisture periodically during the first 24 hours after installation. Avoid applying excessive force during maintenance to preserve the threads of the compression fitting.
