connecting flexible tap tails
I'm in the process of connecting up a new sink with a monobloc tap. The
tap came supplied with flexible tails, one end being a 12mm connector for the base of the taps. Fair enough so far. The other end of the tail, however, has a connector with a captive nut and rubber washer which looks *like* a 1/2 inch BSP as [1], though I've no way of knowing for sure. I was expecting a 15mm compression fitting. The end of my pipework currently has a service valve with a currently empty compression fitting. If I remove the compression nut from the service valve the captive nut on the tail is a perfect fit. Is this how it's inteneded to work? If I wanted to lengthen the tails could I use a coupler [2] and a pipe 1/2" hose [1]? In general, is a 1/2" BSP (or what I have) always compatible with the thread on a 15mm compression joint. Thanks for the help. [1] 1/2" hose - http://www.screwfix.com/app/sfd/cat/pro.jsp?id=66800 [2] Coupler - http://www.screwfix.com/app/sfd/cat/pro.jsp?id=12561 |

The correct fitting is 1/2" MaleIron to 15mm compression so the flat end of the MI seals against the rubber washer. Compression couplers or service isolators with the back-nut and olive removed also work but you may find the end has a bit of damage which stop the seal.

Almost all compression fittings are to BS 864 or equiv and you'll find the thread is 1/2 BSP. -- Ed Sirett - Property maintainer and registered gas fitter.

Thanks, that makes sense - the correct solution would be to add a section of copper pipe and one of these: http://www.screwfix.com/app/sfd/cat/pro.jsp?id=18515 However, if the end of my service valves are free from dents, dings and burrs such that I'd get a good seal the that should be OK. Thanks. |
