Product Information

Full details

The Plumbright Compression Tap Adaptor (P1821) is designed for DIY enthusiasts and professional plumbers who require a reliable, heat-free solution for connecting tap tails to copper pipework. Its primary benefit is the ability to create secure, leak-proof joints without the need for soldering, making it ideal for tight spaces or repairs on wet systems; however, users should note that the compression nut must be tightened carefully to avoid damaging the olive while ensuring a proper seal.

FAQs

Can I use this on plastic pipe?

This fitting is designed for use with copper tubing. Always use the manufacturer-recommended inserts if attempting to use with specific types of plastic piping.

Does this adaptor need PTFE tape?

Generally, no. The compression joint creates a seal via the olive. If you have a persistent micro-leak, a small amount of jointing compound may be used as a secondary measure.

Is this safe for drinking water?

Yes, this product is WRAS approved, which confirms it meets the requirements for use with wholesome water supplies.

Can I take the joint apart later?

Yes, one of the benefits of compression fittings is that they can be dismantled and the pipe reused, provided the olive hasn't been crushed beyond utility.

What tools do I need for installation?

You will need two adjustable spanners or pipe wrenches and a pipe cutter or hacksaw to prepare the copper tubing.

Troubleshooting

Slow drip from the joint after installation

Check if the nut is tight enough. Give it an extra quarter-turn, but ensure you do not overtighten it to the point of distorting the olive.

Difficulty inserting pipe into the adaptor

Ensure the pipe end is perfectly round and de-burred. If the pipe is slightly flattened or has a sharp edge, it will not seat properly.

Olive is spinning freely without tightening

The olive may be damaged or the pipe may be undersized. Inspect the olive for cracks; if damaged, replace it with a new one.

Pros and Cons

Pros

  • No soldering or open flames required
  • Suitable for both hot and cold water systems
  • Easy to install on wet pipework
  • Fully compliant with industry water standards
  • Dismountable for future system modifications

Cons

  • Requires proper tightening to prevent leaks
  • Requires specific copper pipe sizing
  • Bulky compared to solder joints in extremely confined spaces

Setup, Compatibility & Care

To ensure a long-lasting, leak-free connection, follow these setup guidelines:

  1. Pipe Preparation: Ensure the copper pipe end is cut square and is free of burrs or scratches. Use a file or de-burring tool to smooth the cut edge.
  2. Assembly: Slide the compression nut onto the copper pipe, followed by the brass olive. Push the pipe firmly into the adaptor body until it hits the internal stop.
  3. Tightening: Hand-tighten the nut initially. Use two adjustable spanners—one to hold the adaptor body and one to turn the nut—to tighten the joint. Typically, one full turn beyond hand-tight is sufficient; avoid overtightening as this may crush the olive.
  4. Care: Periodically check the joints for signs of moisture or corrosion, especially after initial installation. Do not use chemical sealants or PTFE tape unless absolutely necessary, as the mechanical compression should create the primary seal.
