BSP waste adaptor?

Question

Hi,I have a chrome bottle trap for my basin. Mr BSP has struck again... BESonly do these in 1.5"/40mm BSP with a 75mm seal depth as suggested by BR.The basin, it turns out, presents a 1.25"/32mm thread.(Here we go again - I hate threaded plumbing in the same way I hate RS232 -both have standards - but both have too many!)So, it's either return the trap and try to source from elsewhere, or find a32mm female to 40mm male short adaptor, parallel thread, end bearing washerseal, ideally in chromed brass.Buggered if I can find one online. Do such things exist?TaTim

This one I guess:

for the hint - don't know why I didn't come across that one before. Doesn't state the seal depth by looks identical to mine (probably same make) so it's probably 75mm.

Cheers

Unfortunately, no banana. Popped into Screwfix and bought one. Returned it immediately. The trap seal depth was nowhere near the 75mm required by Doc H for basins. It was probably 38mm as per the BES one. Not sure why they would bother marketing one with an insufficient depth... I wouldn't mind if I was discharging into my "greywater only" stack, but logistics dictate I couple the basin into the bog stack, so I'm keener to keep a decent seal there (there will be an AAV too, but all the same...).

I's about to start the great internet hunt for a brass/chrome bottle or S-trap with the correct parameters.

In the meantime - any ideas on the 1.5 to 1.25" BSP converter? I feel such a thing *should* exist, but google can be unhelpful when searching for things like 1 1/2" etc.

OK - eventually found what I wanted.

The magic words are "BSP reducing bush". After that, ebay saves the day... Now I can use my nice shinely and BR compliant trap and this component being stainless will hardly be noticeable...
