## Questions & Answers

**Q: Can these fit onto the copper pipes**
A: Hi,These are designed to be fitted onto Speedfit 15mm flexible pipe. Copper pipe does not require any inserts. Copper pipes can be used with speedfit fittings without inserts.Kind Regards,

**Q: Can these be used with Speedfit pipes into chrome isolating tap?**
A: I assume you mean a line valve with compression fittings?  If that is the case, a plain pipe insert rather than the Superseal type is the correct one to use.  From John Guest website:- While both types of pipe insert are suitable for hot and cold-water systems as well as underfloor heating and central heating, when using Speedfit pipe and fittings, a plain insert should always be used when plastic pipe is installed with a compression fitting.

Compression fittings vary in terms of depth and in some cases, using a superseal may stop the pipe from going fully into the fitting to ensure the compression ring is sitting on the pipe, and not on the insert.

Always check that the compression fitting is suitable for use with plastic pipework and follow the instructions.
