imperial/metric
are 1/2" to 15m/m and 3/4" to 22m/m copper pipe adapters available, I have
tried B&Q warehouse and Wickes without any luck. Gordon |

Gordon 1/2" and 15mm pipes are so similar that you can use 15mm compression or solder fittings on 1/2" pipe without any problems. 22mm pipe is *slightly* bigger than 3/4". You can use 22mm compression fittings on 3/4" pipe with special olives - with a slightly smaller ID. You can get these at a decent PM but maybe not at the sheds. If you want to use solder fittings to join 22mm and 3/4" pipe, you need special fittings whose two ends are a slightly different size. Again, you can get them from a PM - or probably on-line from the likes of BES. -- Cheers, Set Square ______ Please reply to newsgroup. Reply address is invalid. |

Or if needs must, run a pipe cutter round a 22mm fitting once or twice... not enough to cut into it, but enough to put a dent into the circumferance and reduce the diameter enough to solder it!

Compression yes, but I have experienced the odd failure when using 13mm fittings on 12.7mm (1/2") pipe. Indeed - if SSq had left off "without any problems" then OK. I have found it necessary on many occasions to abrade (with steel wool) 1/2" pipe down quite a lot to get 15mm solder fittings on. They will go eventually though. If they are too tight a fit then the solder won't flow properly and the joint will be suspect for ever more so it's worth working them to an easy fit. Bob Mannix |

Compression yes, but I have experienced the odd failure when using 13mm fittings on 12.7mm (1/2") pipe. I'm not sure which pipes you are talking about. Half inch pipe isn't 12.7mm. The 'half-inch' refers to the nominal bore, so that the OD is larger than this - and very close to that of 15mm (not 13mm) pipe. -- Cheers, Set Square ______ Please reply to newsgroup.

Yorkshire and other soldered fittings *no*. Too harsh, they (15mm fitting onto 1/2" pipe that is) will go with a bit of effort and quite successfully. Most of my radiators are fitted like this (1/2" installarion converted to 15mm then onto rad). There used it be special soldered fittings but I doubt they sell them any more. Yes I bought some not long ago, you can still get them I believe. The 22mm to 3/4" ones are easier to find (as you can't do without) but you can still get the small ones, I believe. Always use compression fittings to join imperial to metric. Easier but not better (but that's not an imperial metric thing!) Bob Mannix |

Last time I tried, I found end feed 1/2 - 15mm and 3/4 - 22mm adaptors at my local PM. -- *The colder the X-ray table, the more of your body is required on it * Dave Plowman London SW To e-mail, change noise into sound. |

I have had failures when using 15mm couplings on older 1/2" pipe. I now only use new pipe for everything and have had no failures at all. SWMBO bought a mixer tap from Ebay. Nice bit of kit. Then you notice French markings for Froid et Chaud. Ne problem, mais. . . Apparently the French go in for 12mm couplings and flexible hoses the size of a pencil. I managed to get some adapters from Plumb Centre and it is all OK apart from the hot flow, which is slower than I would like. -- AJL |

Gordon www.bes.co.uk sell end feed 15mm to 1/2" for 21p or solder ring for £1.50 odd. Also 3/4" to 22mm as well. Last one I got from Jayhard (when they existed) a couple of years ago and when I found I was one short on a Sunday, from Homebase of all places for a rip of cost. |
