Sealing large BSP threads
Discussion
I've looked at pretty much every youtube video out there and I'm still stuck.
I'm connecting a 1.5" male BSP PVC union into a valve (pool multiport) and it weeps even though it's tightened up all the way.
I've tried multiple layers of ptfe, thread sealant, whatever I do it drips. I don't want to go too mad on the ptfe as the female fitting is ABS and will certainly crack if I force it. I can see on the inside that it's touching the base of the valve.
Is there some other trick I need to try? Next step might be to try LS-X on the threads and do it up and wait for it to seal. Seems a lot of the advice out there is US-centric and advice for NPT threads is different to BSP...

They were both parallel so I reckon need an o ring to seal properly without a bodge
But I bought a replacement union that out the box turned out to be tapered and - after an hour - it appears to have sealed with a bit of slic-tite thread sealant (no ptfe tape) .. fingers crossed!
Next is the filter connections.. that’ll be fun
