  • Providing a secure seal on the end of a compression fitting in domestic plumbing installations

  • Capping off radiator tails, unused tap connections, or appliance supply pipes


Installation Guidelines

  1. Prepare the Pipework: Ensure the compression fitting is clean and free of debris or corrosion.

  2. Fit the Nut: Place the compression blanking nut onto the pipe or fitting where sealing is needed.

  3. Tighten Securely: Using a suitable spanner, tighten the nut until secure. Avoid over-tightening, which can damage the fitting.

  4. Check for Leaks: Once installed, turn the water back on and check for any signs of leakage.

Always follow local plumbing regulations and standards. If unsure, consult a qualified plumber.


Care and Maintenance

  • Inspect Periodically: Although designed to be maintenance-free, inspect for leaks during routine system checks.

  • Do Not Overtighten: Excessive tightening can damage the fitting or deform the olive inside the compression fitting.

  • Store in a Dry Environment: Keep spare nuts in a dry place to avoid premature corrosion before installation.


Frequently Asked Questions (FAQ)

Q1: What is a compression blanking nut used for?
A: It’s used to cap or seal the end of a compression fitting in plumbing systems, especially when a branch or connection is no longer required or temporarily disabled.

Q2: Do I need an olive with this blanking nut?
A: In many cases, an olive (compression ring) is used inside the fitting to ensure a secure seal, especially when fitted onto pipe. However, when sealing a compression valve or outlet, an olive may not be required. Always check the application.

Q3: Can it be reused?
A: Yes, as long as it is not damaged or deformed during removal. Always inspect the threads and sealing face before reusing.

Q4: Is it suitable for both hot and cold water systems?
A: Yes, it can be used on hot and cold water pipes, as well as low-pressure heating circuits.

Q5: Will this work on plastic pipe?
A: Yes, but when using with plastic pipe, an appropriate pipe insert is recommended to maintain pipe shape and ensure a proper seal.
