Thread adapter (different pitchs)

[Tidy Max]

Alreet chaps.

Does anybody know of a thread adapter that will connect gas/water fittings to electrical ones.

I.e. 15mm compression end to a 20mm lamp holder?

Something here may help M20 brass lamp holder? - DIYnot.com - DIY and Home Improvement


BUT you question is very vague I.e. 15mm compression end to a 20mm lamp holder? (par for the course here) you don't state if the thread is male or female or both..

most 15mm compression ends are 1/2 bsp 14 teeth per inch and are a parallel thread. so this may help.

Aye, if it can't be crimped, Wago'd or tightened with a Torque Screwdriver they're ducked!!

Soldered ends will look crap. Ive built a desk lamp out of copper pipe and used 15mm elbows and tees. I have some brass bc lamp holders with a 20mm female thread. I knew the compression end had a different pitch thread i just thought i would cross that bridge when i got there....

I am now there lol. Neither the wholesalers, plumbers merchants or commercial "we do everything under the sun" merchants can help.

I will be building a fitting soon with soldered joints but as for this one i am abit stuck ill check the links when i am back at my laptop! Cheers for the advice

Seriously, he's a canny hand at the soldering lark.

Not sure about his Brazing skills though - he probably thinks more in terms of Braising - as in cooking missionaries. :laugh:

Try a hydraulics supplier, metric to BSP fittings are quite common on hydraulic systems.
