## Questions & Answers

**Q: Is this able to be used on a shower mixer unit. I need to extend the pipe thread coming out of the wall?**
A: hi i cannot see any problem as long has the thread coming out of wall is 1/2" bsp i used mine to extend pipes on my radiators.

**Q: Are theres any good to  extend my bar shower from my tiles 1/2bsp (15mm) pipe thread extension**
A: I suspect they would be ideal for the purpose they were first class for my radiator extensions

**Q: I need something to enable me to connect my new shower hose to the shower mixer valve, the last connector is corroded to old hose. Is this correct?**
A: This is a male to female converter which means it will fit another 1/2 inch fitting.  Note that the 1/2 inch refers to the nominal inside diameter of a steel pipe so that the diameter of the thread is much larger.  My only problem with this fitting is that the male thread is parallel and not tapered.  This means that it does not tighten up hence you need a lot of ptfe tape.  Even then you might find that, with time, you may get a slight leak.

**Q: What's the maximum outer diameter?**
A: 25mm. Note that the photo is confusing, showing three different items. You only get the length you order. Items are well made with internal hex slot to enable fixing/removing without the need to grip the exterior finish.

*by P***N on Reviewed in the United Kingdom on 10 June 2024*

So, I wanted to replace a radiator but the only radiators I could find were 40mm narrower than the existing radiator. I didn't want to have to drain the system to have the pipework modified. Bought 2x 20mm extensions and new 40mm narrower radiator and these extensions were a perfect solution to bridge the gap.

    problem
  

*by T***G on Reviewed in the United Kingdom on 20 December 2014*

I wanted this item to extend below a towel radiator where an electric heating element was to be fitted. The extender has an internal hexagon key head. This reduces the internal size below the size of the heating element. So no good for this application
